Initial effects of wood ash application to soil and soil solution chemistry in a small, boreal catchment: Geoderma, 187-188, p. 85-93, illus. incl. 5 tables, sketch map, 34 ref., October 2012.
With the conception that whole tree harvesting leads to an impoverishment of forest soils wood ash application is recommended, with the foremost benefits being increased pH in soil and subsequent surface waters, and recycling of nutrients from the wood ash. In this investigation a small boreal catchment in central Sweden was studied for 2 years before and 2 years after treatment with the maximum recommended dose, 3 tonnes/ha, of crushed, self-hardened wood ash. The sampling area was situated in a slope towards a stream, to include the effect on both recharge- and discharge areas with different soil constitutions. The soil solution chemistry, exchangeable pool of cations and potential heavy metal accumulation in berries were studied. Temporary increases in soil solution concentration were found for K in the recharge area and Ca and SO4 in the discharge area when comparing ashed and control areas. No change in exchangeable cations was observed during the study period, and no increase of heavy metals in bilberries did occur. These small changes in the constitution of the soil solution do not suggest wood ash application as a method to improve soil quality in an initial phase.

A drive point application of the Guelph permeameter method for coarse-textured soils: Geoderma, 187-188, p. 59-66, illus. incl. 4 tables, 33 ref., October 2012.
The Guelph Permeameter (GP) is a widely used well/auger-hole method for in-situ determination of field-saturated hydraulic conductivity (Kfs) and sorptive number (a*) in the vadose or unsaturated zone. Its application can be difficult, however, in gravelly materials which are problematic to auger, and in un-cohesive sandy materials which collapse during the augering process or upon wetting of the unlined well. We circumvented these issues, by replacing the GP well with a conically tipped well screen or "drive point" which is pushed, driven, rotated or vibrated to the desired depth. We also developed a steady flow analysis to account for the fact that water discharge through the drive point screen is solely radial, rather than both radial and vertical as in the original GP method. The HYDRUS-2D numerical simulation model was used to determine appropriate shape values (CDP) for the drive point analysis; and an empirical regression equation was developed to convert the discrete CDP values into continuous shape functions for porous materials with negligible-moderate, strong and very strong capillarity. In a well-sorted medium-coarse sand, the drive point method produced Kfs and a* values which were plausible and consistent with other data from the field site. The original GP method, on the other hand, under-estimated the drive point results by factors of 2.1-3.1, which may have been caused by progressive collapse of the unlined GP well, and/or gradual sinking of the GP outflow tip into the unprotected well base. It was concluded that the drive point GP method can provide convenient and accurate estimates of Kfs and a* in materials where hydraulic properties are not substantially altered by the disturbance of drive point installation.

Analysis of a deep-seated landslide in permafrost, Richardson Highway, south-central Alaska: Environmental & Engineering Geoscience, 18(3), p. 261-280, illus. incl. 4 tables, sketch map, 26 ref., August 2012.
A portion of the Richardson Highway near Glennallen, Alaska, is threatened by slope movement in an area where the highway travels along a bluff overlooking the Copper River. Analysis of aerial photographs indicates that portions of the bluff have experienced an average of 1.5 m of retreat per year since 1979, and gully erosion has completely obliterated portions of the pre-1965 highway alignment. The subsurface consists of a 1.5-m-thick surficial silt layer underlain by frozen, ice-rich clayey soils with an average annual temperature of -0.56°C. At 16 m below the ground surface, the soils become ice-poor and coarser grained. In situ measurements, soil creep tests, and slope stability analysis indicate that the ice-rich clayey soils are experiencing movement, with creep velocities of up to 2.5 cm per year. This deep-seated creep results in fracturing of the near-surface soil layer that is manifested at the surface by cracks, scarps, and back-tilted blocks. Groundwater perched above the permafrost table and seeping toward the bluff face facilitates the rapid retreat of the bluff edge through the formation of gullies.

12081480 Palviainen, Marjo (University of Helsinki, Department of Forest Sciences, Helsinki, Finland); Starr, Mike and Westman, Carl Johan. The effect of site fertility and climate on current weathering in Finnish forest soils; results of a 10-16 year study using buried crushed test-rock material: Geoderma, 183-184, p. 58-66, illus. incl. 5 tables, 40 ref., August 2012.
Knowledge of the weathering rates in forest soils is needed when nutrient balances and the sustainability of silvicultural practices are estimated. The effects of site fertility and climate on weathering rates were studied in boreal coniferous forest soils in Finland by following transformations in crushed rock (Spectrolite, a dark, anorthosite feldspar dominated gabbro) confined in porous bags inserted into E-, B- and C-horizons along fertility and climate gradients, and left to weather for 10, 11 or 16 years. Organic carbon (OC) was accumulated in E-horizon incubated crushed test-rock material and it was more acidified and weathered than that deeper in the soil. There was a tendency for faster weathering of the C-horizon bags in the fertile sites than in the poor sites. Multivariate analyses indicated that more OC was accumulated in the bags in fertile sites than in poor sites, and that the crushed rock was more weathered in north than in south Finland although temperature sum and precipitation decreased northwards. The results suggest that humidity is an important climatic factor determining weathering rates and that fertile sites have greater potential to release base cations through weathering and sequester C to mineral surfaces than do poor sites.

Estimating ground water recharge through unsaturated flow modelling; sensitivity to boundary conditions and vertical discretization: Journal of Hydrology, 452-453, p. 90-101, illus. incl. 2 tables, sketch map, 40 ref., July 25, 2012.
Unsaturated flow modelling is increasingly being used to estimate potential groundwater recharge. A review of previous studies found that unit-gradient and fixed water table lower boundary conditions have been applied to models of both constant and variable vertical grid spacing (discretization). In order to provide a general guidance, this work studies the effect of both discretization and boundary conditions on simulation times and estimated fluxes at the water table, using one-dimensional models of 2, 4, 6, and 12 m comprised of sand, sandy loam, loamy sand, and loam. The study uses climatological data from the Boreal Plain of northern Alberta, Canada. Because of the long-term average water deficit and the thick unconsolidated glacial deposits, unsaturated flow is expected to be vertical, both downward and upward, and inter-annual changes in water storage will be important. Long-term simulations (1919-2007) that comprised both wet and dry cycles, reveal that when a variable vertical discretization at both the top and bottom of the columns (varying from 0.1 to 10 cm) is utilized, a balance between simulation accuracy and running time can be achieved. It is also found that whenever the unsaturated flow modelling approach is used to estimate potential groundwater recharge, a fixed-head lower boundary condition should be selected because it also allows upward flux from the water table during dry periods, a situation that prevails on both sub-humid and semi-arid areas, where accurate groundwater recharge estimates are needed the most. However, it should be kept in mind that the use of a fixed water table is a simple representation of the regional water table, which in reality interacts with the regional groundwater flow and surface water bodies (e.g., lakes and wetlands).

S. and Jensen, M. B. Modelling the impact of soakaway retrofits on combined sewage overflows in a 3 km2 urban catchment in Copenhagen, Denmark: Journal of Hydrology, 452-453, p. 64-75, illus. incl. sketch maps, 47 ref., July 25, 2012.
Stormwater infiltration measures such as soakaways are expected to be part of future urban drainage systems. However, few studies exist on the effect of extensive stormwater infiltration through soakaways on the overall urban water system, including sewers and groundwater, at city catchment scale. In particular such estimates have not been made in real urban settings with multiple physical and structural constraints. This paper presents a methodology for conducting such an analysis, and provides quantitative estimates of the effects on the urban water flows. Using an interdisciplinary, three-step approach that employed GIS analyses and physically distributed, dynamic pipe flow modelling in an iterative manner, this study estimates the impact of infiltration on combined sewage overflows (CSOs) in a 3 km2 urban catchment in Copenhagen. The first step was the creation of a baseline scenario. The second step led to a potential infiltration scenario where 65% of the total impervious area was connected to soakaways, and resulted in an estimated reduction in annual sewage overflow volume of 68%. This scenario was then further developed in the third step by adding groundwater constraints, which formed a more realistic scenario where only 8% of the impervious area was connected to soakaways and the reduction in CSO volume was 24%. The potential and realistic scenarios were modelled both with hydraulic coupling between soakaway and sewer, and as fully disconnected. Results show that infiltration is constrained mainly by the quality of the stormwater runoff from roads and limited land availability in the potential infiltration scenario, and by low-permeable soils and a problematically high groundwater level in the realistic infiltration scenario. The hydraulically coupled model gives higher CSO volume than the fully disconnected model for the potential infiltration scenario, whereas no difference is seen between these two models in the realistic infiltration scenario. The effect of infiltration on combined sewer overflows is thus expected to be limited in the case study area. General conclusions are that groundwater constraints are important to consider when evaluating the potential of infiltration-based stormwater management, and that it is important to include the hydraulic coupling between soakaways and sewers in models if soakaways are expected to give overflow to the sewers.

12076915 Tye, Andrew M. (British Geological Survey, Kingsley Dunham Centre, Nottinghamshire, United Kingdom); Kemp, Simon J.; Lark, R. Murray and Milodowski, Antoni E. The role of peri-glacial active layer development in determining soil-regolith thickness across a Triassic sandstone outcrop in the UK: Earth Surface Processes and Landforms, 37(9), p. 971-983, illus. incl. 6 tables, 57 ref., July 2012.
This paper examines the weathering processes that have combined to produce the distribution of soil-regolith (SR) thickness across the Triassic Sherwood Sandstone Group outcrop (750 km2) in Nottinghamshire, UK. Archive borehole logs (n = 282) taken across the outcrop showed that SR thickness had mean and median depths of »1·8 and 1·5 m, respectively. Cores were taken from a forested site to depths »3 m for geochemical analysis. At this site the SR thickness was »1·7 m. Analysis of the loss of elements, compared to bedrock using mass balance calculations (t) showed that all the calcite and gypsum cement had been removed to depths of >3 m. Thus the major difference between the SR and the underlying saprolite was that the former exists as loose sand as opposed to a semi-durable rock. Scanning electron microscopy (SEM) analysis of core samples suggested that the non-durable rock or saprolite had greater cementation of clay particles. We propose that the mechanism through which the clay cement (and other interlocking grain bonds) was eased apart was through freeze-thaw processes associated with the summer 'active layer development (ALD)' during the last glacial activity in the UK. We tested this theory by developing a Monte Carlo simulation based on a simplified version of the Stefan equation. Current Arctic datasets of air and ground temperatures were obtained to provide reasonable starting conditions for input variables. These were combined with known data for thermal conductivity, bulk density and moisture content of the Sherwood Sandstone regolith. Model predictions (n = 1000) of the distribution of SR thickness accurately reflect the observed distribution thickness from the borehole logs. This is strong evidence that freeze-thaw and 'ALD' processes are major factors in determining the thickness of SR across this outcrop. Abstract Copyright NERC 2012.

Thermal conductivity and thermal diffusivity of cores from a 26 meter deep borehole drilled in Livingston Island, maritime Antarctic: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 7-11, illus. incl. 3 tables, sketch map, 27 ref., June 15, 2012.
During the month of January of 2008 a borehole (Permamodel-Gulbenkian 1 - PG1) 26 m deep was drilled on the top of Mount Reina Sofia (275 m a.s.l.) near the Spanish Antarctic Station of Livingston Island, South Shetland Islands. Cores from 1.5 m to about 26 m deep were collected for measuring several physical properties. The objective of the present work is to report the values of the thermal conductivity and the thermal diffusivity that were measured in the cores from the borehole and the heat production that was estimated for the geological formations intercepted by it. Seven cores were selected to measure the thermal conductivity and the thermal diffusivity. The measured values for the thermal conductivity vary from 2.6 W/mK to 3.3 W/mK while the measured values for the thermal diffusivity vary from 1.1´10-6m2/s to 1.6´10-6m2/s. Both thermal conductivity and thermal diffusivity, on average, show a slight increase with depth. Average heat production was also estimated for two portions of the borehole: one from 2 to 12 m and the other from 12 to 25 m. A gamma-ray spectrometer was used to estimate the concentrations of uranium, thorium, and potassium of the cores, from which the heat production per unit volume was calculated. The estimated heat production for the first half of the borehole is 2.218 mW/m3 while for the second half it is 2.173 mW/m3; these heat production values are compatible with acidic rock types. Porosity and density were also estimated for the same cores.

Hydrogeochemistry of sulfate-affected landscapes in Keller Peninsula, maritime Antarctica: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 55-61, illus. incl. 5 tables, sketch map, 28 ref., June 15, 2012.
Keller Peninsula, located in King George Island, has a typical Maritime Antarctica climatic regime, with higher temperatures and rainfall than other areas in Continental Antarctica. The main outcropping rocks are pyritized andesites, volcaniclastics and basalts. Recent pedological investigation indicated that the presence of sulfides in Keller Peninsula accelerates the weathering process. The aim of this work was the determination of the geochemical background in water channels following geomorphological gradients in Keller Peninsula, Maritime Antarctica. We delimited and mapped all catchments in Keller Peninsula using GIS techniques and field observations. Water samples were analyzed for twenty-nine elements by ICP-OES and IEC, after the proper treatments. Eight catchments were identified as sulfide-affected, although water pH was nearly neutral. The ionic concentration in solution was high, both in non-affected and sulfide-affected catchments, with a trend of greater values in the latter, and changing downslope. Concentration values are above the range of other hydrogeochemical studies from elsewhere in Antarctica. The values of molar ratio HCO3-:(Ca+Mg)2+ and Na+:Cl- indicated the absence of carbonate-bearing rocks. Local precipitation of evaporites, as gypsum and epsomite was confirmed by the Ca2+:SO42- and Mg2+:SO42- molar ratios. The high ionic concentration in sulfide-affected areas illustrates the role of sulfate soil formation in this part of Antarctica.

12076820 Guglielmin, Mauro (Insubria University, Sciences, Information and Communication, Varese, Italy); Worland, Michael Roger and Cannone, Nicoletta. Spatial and temporal variability of ground-surface temperature and active layer thickness at the margin of maritime Antarctica, Signy Island: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 20-33, illus. incl. 2 tables, sketch map, 56 ref., June 15, 2012.
A CALM grid with a data logger system to monitor the active layer thermal regime was established on Signy Island (60°43'S, 45°38'W at 80 m a.s.l.) in December 2005. The active layer at each of the 36 nodes of the grid was monitored measuring the ground temperature at least at 4 different depths between 0.02 and 0.4 m at the end of the summer season. In addition, within the grid, we selected four sites closely spaced (in a ray of 25 m) three of which with the same topographical characteristics (north facing aspect) but different vegetation coverage (one bare ground, BG1 and two sites with different vegetation: Andreaea sp. and Sanionia uncinata) and the fourth (BG2) it is as BG1 a bare ground but with south facing aspect. In particular, 4 thermistors were located at depths of 0.02, 0.3, 0.6, and 0.9 m at BG2 and at the Andreaea sp site, 9 thermistors at 0.02, 0.3, 0.6, 1, 1.2, 1.4, 1.6, 2, and 2.5 m at BG1 and at 0.02 and 0.6 m of depth at Sanionia site. Generally, with the same aspect, a thick vegetation cover (as in Sanionia site) provides a greater insulative effect than a thinner vegetation cover (as in Andreaea site) or bare ground (BG1) because vegetation both shades and insulates the ground resulting in a reduction in summer heat flux. Ground Surface Temperature (GST) was colder and more buffered in spring and summer under the vegetated ground than in BG1, although the coldest GST and lowest Thawing Degree Days (TDD) were recorded at BG2 and related to its southern aspect. Our data confirm that air temperature is the main driver of GST, as already reported both in the Arctic and Antarctic. We also found that the effect of air temperature changes seasonally, being drastically reduced in winter and, to a lesser extent, in fall and spring, when there is generally thin snow cover (<30 cm). During the summer, when snow cover is usually absent, the air temperature is the dominant driver, although incoming radiation also had an effect on the northern exposed bare ground and to a lesser extent on the vegetated and southerly exposed bare ground. The active layer ranges between 81 and 185 cm on the 4 continuously monitored sites and, considering the sites with the same aspect, it is thicker under bare ground (between 10% up to more than 100%) than under vegetated ground, confirming previous observations in the Arctic and Antarctic. However at our sites, climate forcing has no effect on the active layer thickness, enhancing the role of soil properties including the periods of high moisture content and lateral flow of water. The lack of a statistically significant regressions between GST and active layer thickness could be due to the limited study period (four years) and/or to the variation with time of changes in soil characteristics such as soil moisture, and the possible occurrence of non-conductive heat transfer processes including the lateral flow of water. Further data are required to understand the role of moisture and possible ground water circulation within the active layer to explain the unexpected strong dichotomy between the GST regime and active layer thickness.

Schmidt Hammer studies in the maritime Antarctic; application to dating Holocene deglaciation and estimating the effects of macro-lichens on rock weathering: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 34-44, illus. incl. 3 tables, sketch maps, 68 ref., June 15, 2012.
In order to contribute to the reconstruction of the deglaciation history of the Marguerite Bay area (~68°S, Maritime Antarctic) and to estimate the rock weathering rate in this Antarctic sector, 28 sites (7 on Rothera Point and 21 on Anchorage Island) were characterised using Schmidt Hammer values. The weathering effect of two of the most widespread species of macrolichens in this area (Usnea sphacelata and Umbilicaria decussata) was tested at 5 different sites on Rothera Point. Schmidt Hammer data, in conjunction with recent 14C age, suggest a deglaciation age for the Marguerite Bay area of around 12 ka, and an average uplift rate of 5.4 mm year-1 on Anchorage Island for the period between 3.3 and 5.2 ka. The weathering rates are extremely slow (e.g. three times slower than reported in Norway). Our data confirm that lichens exert a strong impact on weathering, decreasing the Schmidt Hammer R-values on lichenised surfaces by a factor of 3-4 compared to bare rock surfaces. The effect of lichens on weathering is mainly due to edaphic conditions and the type of the lichen involved rather the period of exposure.

Recently the research on permafrost, periglacial morphology and processes had a great stimulus especially from the International Polar Year. Permafrost areas of continental Antarctica with its extreme dry and cold environment can be considered an analog of extraterrestrial landscapes like those on Mars, but also preserve much paleoclimatic information of this crucial part of the global climatic system. On the other hand, maritime Antarctica is one of the areas of the world currently affected by the greatest air warming and provides a unique opportunity to understand the impacts of climate change on permafrost and its related ecosystems. Despite the significant recent progress, some gaps on permafrost distribution still remain as the network for permafrost and active layer monitoring needs further enlargement and better standardization. Ground ice, its age and stability over time need further investigation, as well as the role of living organisms on the weathering processes within the cryotic rocks, the landscape evolution of continental Antarctica could be improved providing potential implications also for a better understanding and modeling of life and landscape evolution of other planets.

The geothermal field at Hofsstadir northern Snaefellsnes peninsula, Iceland produces low-temperature geothermal water with about 5.4 ppm salinity. The fluid temperature is 87°C, near the reservoir temperature of 90°C as assessed from mineral solution/equilibrium conditions. The stable isotopic ratios d2H and d18O show that the water is significantly lighter than present day precipitation anywhere on the Snaefellsnes peninsula. It is offset from the meteoric water line towards isotopically depleted 18O values, most likely due to CO2(g) - H2O exchange at earlier times during evolution of the system. Such a concentration of stable isotopes is unique for Icelandic groundwaters and has not been encountered anywhere else in Iceland. The water may either have its origin far north of the Bay of Breidafjorthur in the highland of the western fjordlands or dating back to a Pre-Holocene age when local precipitation was considerably lighter due to the cold climate at that time. The water is highly concentrated in Ca in comparison with seawater and also compared to that of geothermal saline water elsewhere, which indicates intensive and prolonged water-rock interaction. The 14C concentration is low, about 7.4 pMC (percent modern C), compared to the cold local groundwater of about 74.6 pMC. d13C for the thermal and cold waters is -4.9 ppm and -2.3 ppm, respectively. The geothermal water is used for heating the small town of Stykkisholmur through a central heat exchanger plant due to the high salinity of the water. The outbuilding of a health resort has been planned and the water has been used successfully for the treatment of psoriasis and is claimed to have beneficial effects in bathing therapy for rheumatism as well as for drinking cures.

Periglacial processes and landforms in the South Shetland Islands (northern Antarctic Peninsula region): in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 62-79, illus. incl. 4 tables, geol. sketch maps, 87 ref., June 15, 2012.
Periglacial processes and landforms together with the presence of permafrost are among the most relevant geomorphological elements in the northern Antarctic Peninsula region. Their distribution affects the hydrology and has consequences for the ecosystems of the ice-free areas. In this paper a compilation of the different types of periglacial landforms and processes occurring in the South Shetland Islands is carried out and their spatial distribution is analysed. Furthermore, the relationships of the periglacial landforms with local conditions and permafrost distribution have been taken into account. A total of thirty three types of periglacial landforms were identified and considered in this work. Patterned ground and stone fields are the most common periglacial landforms, which are located within a wide altitudinal range and mainly on platforms. Field studies, aerial photograph and satellite imagery interpretation were implemented to produce detailed maps from ten areas with different geological, geomorphological and relief characteristics, including the largest and most relevant ice-free areas within the archipelago, showing the presence and spatial distribution of periglacial landforms. This work shows that the periglacial environment, primarily conditioned by the regional climatic conditions, has a great diversity in the studied region and that the distribution of the periglacial landforms is also related to local relief and geomorphological characteristics, lithology, hydrogeology, and presence of permafrost where altitude plays an important role. Periglacial phenomena are widespread above 10 m a.s.l. and are especially active on slopes and platforms between 30 and 100 m a.s.l. The spatial distribution of periglacial landforms helps to identify the presence of permafrost that is dominant above 25-30 m a.s.l. and more than 70% of the surface is occupied by active layer-related landforms.

Susceptibility modelling of hummocky terrain distribution using the information value method (Deception Island, Antarctic Peninsula): in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 88-95, illus. incl. 4 tables, sketch maps, 32 ref., June 15, 2012.
The hummocky terrains of Deception Island (Antarctic Peninsula) are continuous surfaces with decimetre to metre wide and decimetre depth bumps located mainly in the lower section of sloping lapilli and scoria terrains. A detailed study site between Cerro Caliente and Crater Lake was selected for the detailed mapping of hummocky terrains and for modelling their spatial distribution according to controlling geographical factors. A model of the susceptibility of occurrence of the hummocky terrains was created using the information value method, together with five independent variables: elevation, slope, global summer radiation, total curvature and lithology. Success and prediction rate curves were used for model validation and the Area Under the Curve index was used to quantify the levels of performance and prediction. The results were of high quality with a success rate of 88% and a prediction rate of 78%. The classes of the independent variables with more relevance in the occurrence of hummocky terrains were: elevation between 20-30 m and 60-70 m; concave or rectilinear/flat areas; slopes between 8 and 12°; tuff cones and maar deposits and global summer radiation between 1.8 and 2.0 TJm-2. The good quality of the modelling results supports its use for assessing the future potential for formation of new hummocky terrain areas, or even to estimate the spatial distribution of buried ice within the permafrost environment of Deception Island.

Active layer temperature in two Cryosols from King George Island, maritime Antarctica: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 12-19, illus. incl. 7 tables, sketch map, 33 ref., June 15, 2012.
This study presents soil temperature and moisture regimes from March 2008 to January 2009 for two active layer monitoring (CALM-S) sites at King George Island, Maritime Antarctica. The monitoring sites were installed during the summer of 2008 and consist of thermistors (accuracy of ±0.2°C), arranged vertically with probes at different depths and one soil moisture probe placed at the bottommost layer at each site (accuracy of ±2.5%), recording data at hourly intervals in a high capacity datalogger. The active layer thermal regime in the studied period for both soils was typical of periglacial environments, with extreme variation in surface temperature during summer resulting in frequent freeze and thaw cycles. The great majority of the soil temperature readings during the eleven month period was close to 0°C, resulting in low values of freezing and thawing degree days. Both soils have poor thermal apparent diffusivity but values were higher for the soil from Fildes Peninsula. The different moisture regimes for the studied soils were attributed to soil texture, with the coarser soil presenting much lower water content during all seasons. Differences in water and ice contents may explain the contrasting patterns of freezing of the studied soils, being two-sided for the coarser soil and one-sided for the loamy soil. The temperature profile of the studied soils during the eleven month period indicates that the active layer reached a maximum depth of approximately 92 cm at Potter and 89 cm at Fildes. Longer data sets are needed for more conclusive analysis on active layer behaviour in this part of Antarctica.

12076822 Moura, Pedro Adnet (Universidade Federal Rural do Rio de Janeiro, Instituto de Florestas, Seropedica, Brazil); Francelino, Marcio R.; Schaefer, Carlos Ernesto G. R.; Simas, Felipe N. B. and de Mendonca, Bruno A. F. Distribution and characterization of soils and landform relationships in Byers Peninsula, Livingston Island, maritime Antarctica: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 45-54, illus. incl. 3 tables, geol. sketch map, 41 ref., June 15, 2012.
This paper presents the spatial distribution of soils from the northern part of Byers Peninsula, Livingston Island, which is the largest ice-free area of the South Shetlands archipelago, Maritime Antarctica. Physical and chemical characteristics are presented for 23 soil profiles. Soil parent materials vary from marine sedimentary to volcanic and volcanoclastic rocks, intruded by igneous bodies. To assess soil-landscape relationships, twenty-three soil profiles were described and sampled. Soil samples of selected horizons were submitted to chemical, physical and mineralogical analyses. Soil mapping was based on the soil profiles, integrated with the existent topographic map (1:25.000 scale), a digital elevation model, the geological map and a satellite image. Twenty different soil units were identified and mapped. According to the World Reference Base for Soil Resources (WRB) system, soils were classified as Fluvisols, Regosols, Leptosols or Cryosols, which correspond mostly to Fluvents, Orthents/Psamments, Inceptsols and Gelisols, respectively, according to the Soil Taxonomy. Soils from northern Byers Peninsula are generally shallow and coarse textured, with low organic matter content. Three soils from the rocky platforms of the northern coastal region possess ornithogenic character, with lower pH, higher P, Al3+ and organic C values when compared to soils not influenced by sea birds. In non-ornithogenic soils, the presence of easily weatherable minerals in the clay fraction indicates that physical weathering occurs with limited chemical alteration of primary minerals. The influence of penguin and other birds on coastal soils alters clay mineralogy, with formation of poorly crystalline P-rich phases. A better understanding of the depth of the permafrost table and the spatial distribution of permafrost is necessary for a more conclusive classification of Cryosols or Gelisols.

12076825 Putkonen, Jaakko (University of North Dakota, Department Geology and Geological Engineering, Grand Forks, ND); Morgan, Daniel J. and Balco, Greg. Regolith transport quantified by braking block, McMurdo dry valleys, Antarctica: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 80-87, illus. incl. 1 table, sketch map, 41 ref., June 15, 2012.
The McMurdo Dry Valleys of Antarctica are today a hyper-arid, polar desert. Prior work has identified several in situ volcanic ashes (6-11 Myr old) resting on the surface regolith that suggests the persistent stability of the regolith surfaces and climate. However, our field observations of characteristic regolith bulges above and cavities below boulders that are lodged in the hillslope (braking blocks) contradict the apparent preservation of the regolith surfaces. To quantify the regolith mobility we modeled the downslope regolith transport around large boulders in the Dry Valleys using a finite difference regolith-transport model. To guide our modeling effort, we surveyed the detailed topography around one large boulder in the field. Model results fit the observed topography well and allow for the calculation of the minimum volume of regolith per unit width of slope that was mobilized (>4 m3/1 m width). To assess the general applicability of the braking block analysis on random boulders on hillslope we surveyed the topographic characteristics adjacent to 997 boulders on 10 separate hillslopes. The bulge-cavity development appears to be sensitive to: 1) the adjacent obstructions that restrict the free movement of the regolith around the given boulder, and 2) the inherent surface roughness. Even though, theoretically boulders of all sizes should have a cavity-bulge pair surrounding them, the signal to noise ratio prevented us from extracting such measurements reliably on boulders whose diameter was smaller than about 1 m, on boulders that sat on bedrock covered by a thin veneer of regolith, and on boulders that were part of an actively aggrading talus. The limiting minimum topographic diffusivity was found to be 10-6m2/yr. Over time periods of millions of years this is enough to rework the surfaces and highlights the intriguing contradiction between the preserved ashes and the observed regolith transport.

Aeolian flux of biotic and abiotic material in Taylor Valley, Antarctica: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 102-111, illus. incl. 5 tables, sketch map, 37 ref., June 15, 2012.
We studied patterns and mechanisms controlling wind-driven flux of soils and associated organic matter in Taylor Valley, Antarctica over a 10-year period using passive aeolian traps and dynamic mass erosion particle counters. Deployment of the particle counters near meteorological stations allowed us to compare the magnitude of soil flux with data on prevailing wind. Particulate organic C, N and P measurements on transported sediment allowed us to examine connectivity of wind dispersed organic matter among landscape units. Most sediment entrainment occurred within 20 cm of the soil surface during "saltation bursts" that occupied <3% of the total time within a year. These bursts corresponded to periods of strong fohn winds where wind velocities were>&eq;20 m s-1. Sediment movement was highest in the up-valley reaches of Taylor Valley and transport was down-valley towards McMurdo Sound. The general paucity of biological organic matter production throughout the McMurdo Dry Valleys, in concert with low fluvial transport, makes aeolian distribution or organic C, N and P an important factor in the distribution of organic matter throughout this polar desert ecosystem and increases connectivity among the ecosystem components.

Periglacial features in Patriot Hills, Ellsworth Mountains, Antarctica: in Advances in permafrost and periglacial research in Antarctica (Guglielmin, Mauro, editor; et al.), Geomorphology, 155-156, p. 96-101, illus. incl. sketch maps, 30 ref., June 15, 2012.
This work describes periglacial features identified at Patriot Hills, at the southernmost part of Ellsworth Mountains, Antarctica, during the 2008/2009 Brazilian Antarctic Expedition, and discusses their morphogenetic environment. Identified periglacial features were classified into: (a) rock glacier-like landform; (b) slightly creeping debris-mantled slopes; (c) steep debris-mantled slopes; and (d) rock falls. Results obtained from sediment sample analysis suggest activity and passive movement of a rock glacier-like landform, albeit minimal. Wind seems to play an important role in Patriot Hills local geomorphology. Periglacial features such as slightly creeping debris-mantled slope appear to have preferred slope orientation. They are commonly found onto slopes where the katabatic wind flows down. Slopewash and groundwater movement processes may be limited or non-existent since most snow disappears through sublimation

12076705 Garrido, Estrella (Universidad Austral de Chile, Escuela de Graduados, Chile) and Matus, Francisco. Are organo-mineral complexes and allophane content determinant factors for the carbon level in Chilean volcanic soils?: Catena (Giessen), 92, p. 106-112, illus. incl. 2 tables, 29 ref., May 2012.
The existing information on soil carbon (C) stabilization in allophanic soils is conflicting because active Al3+ and sesquioxides (i.e., the oxides/hydroxides of Al and Fe) as a stabilizing agent of soil C are emphasized in opposition to allophane and imogolite type materials. Two hypotheses were tested in this study: 1) Al (and Fe) complexed with soil C and allophane content are the key variables to explain the soil C level in Chilean allophanic soils, and 2) the existing metal-SOM complex and short-range ordered aluminosilicate minerals in allophanic soils mainly result from soil pH variation and competition between Al (and Fe) for SOM and allophane formation. This study established the relationship among different soil properties such Al-, Fe-complexes and allophane content on soil C levels in Chilean volcanic soils as well as the effect of soil pH on metal-OM complexes. A total of 45 soil samples from 15 soil pedons were sampled at 0-0.1, 0.1-0.2 and 0-2-0.4m. The soil samples were analyzed for the content of soil organic C, allophane, clay, silt and Na-pyrophosphate extraction (Alp, Fep, Cp) and soil pH (water). We examined the relationship between the soil C content and soil properties using simple and multiple linear regressions. The silt and clay contents explained little, while the allophane, soil pH and Alp explained most of the soil C variation. We found an inverse relationship between soil pH and Alp (and Fep), indicating that the soil pH was significantly correlated with Alp and Fep, while the allophane content was positively related with soil pH. The results also showed a higher atomic ratio (Al+Fe)p:Cp in deep (0.2-0.4m) horizons; the opposite was true in the top soil horizon (0-0.1m), supporting the idea that SOM in deep soils is saturated with Al and Fe, leaving extra metal to react with silica for allophane formation.

12076995 Tsuji, Takeshi (Kyoto University, Graduate School of Engineering, Kyoto, Japan); Johansen, Tor Arne; Ruud, Bent Ole; Ikeda, Tatsunori and Matsuoka, Toshifumi. Surface-wave analysis for identifying unfrozen zones in subglacial sediments: Geophysics, 77(3), p. EN17-EN27, illus. incl. 1 table, 34 ref., May 1, 2012. Includes appendices.
To reveal the extent of freezing in subglacial sediments, we estimated S-wave velocity along a glacier using surface-wave analysis. Because the S-wave velocity varies significantly with the degree of freezing of the pore fluid in the sediments, this information is useful for identifying unfrozen zones within subglacial sediments, which again is important for glacier dynamics. We used active-source multichannel seismic data originally acquired for reflection analysis along a glacier at Spitsbergen in the Norwegian Arctic and proposed an effective approach of multichannel analysis of surface waves (MASW) in a glacier environment. Common-midpoint crosscorrelation gathers were used for the MASW to improve lateral resolution because the glacier bed has a rough topology. We used multimode analysis with a genetic algorithm inversion to estimate the S-wave velocity due to the potential existence of a low-velocity layer beneath the glacier ice and the observation of higher modes in the dispersion curves. In the inversion, we included information of ice thickness derived from high-resolution ground-penetrating radar data because a simulation study demonstrated that the ice thickness was necessary to estimate accurate S-wave velocity distribution of deep subglacial sediment. The estimated S-wave velocity distribution along the seismic line indicated that low velocities occurred below the glacier, especially beneath thick ice (~1300 m for ice thicknesses larger than 50 m). Because this velocity was much lower than the velocity in pure ice (~1800 m/s), the pore fluid was partially melted at the ice-sediment interface. At the shallower subglacial sediments (ice thickness less than 50 m), the S-wave velocity was similar to that of the pure ice, suggesting that shallow subglacial sediments are more frozen than sediments beneath thick ice.

12081490 Wang Chengjie (Inner Mongolia Agricultural University, College of Ecology and Environmental Science, Huhhot, China); Tang Shiming; Wilkes, Andreas; Jiang Yuanyuan; Han Guodong and Huang Ding. Effect of stocking rate on soil-atmosphere CH4 flux during spring freeze-thaw cycles in a northern desert steppe, China: PloS One, 2012(E36794), illus. incl. 4 tables, 26 ref., May 8, 2012.
Methane (CH4) uptake by steppe soils is affected by a range of specific factors and is a complex process. Increased stocking rate promotes steppe degradation, with unclear consequences for gas exchanges. To assess the effects of grazing management on CH4 uptake in desert steppes, we investigated soil-atmosphere CH4 exchange during the winter-spring transition period. The experiment was conducted at twelve grazing plots denoting four treatments defined along a grazing gradient with three replications: non-grazing (0 sheep/ha, NG), light grazing (0.75 sheep/ha, LG), moderate grazing (1.50 sheep/ha, MG) and heavy grazing (2.25 sheep/ha, HG). Using an automatic cavity ring-down spectrophotometer, we measured CH4 fluxes from March 1 to April 29 in 2010 and March 2 to April 27 in 2011. According to the status of soil freeze-thaw cycles (positive and negative soil temperatures occurred in alternation), the experiment was divided into periods I and II. Results indicate that mean CH4 uptake in period I (7.51 mg CH4-C m-2 h-1) was significantly lower than uptake in period II (83.07 mg CH4-C m-2 h-1). Averaged over 2 years, CH4 fluxes during the freeze-thaw period were -84.76 mg CH4-C m-2 h-1 (NG), -88.76 mg CH4-C m-2 h-1 (LG), -64.77 mg CH4-C m-2 h-1 (MG) and -28.80 mg CH4-C m-2 h-1 (HG). CH4 uptake activity is affected by freeze-thaw cycles and stocking rates. CH4 uptake is correlated with the moisture content and temperature of soil. MG and HG decreases CH4 uptake while LG exerts a considerable positive impact on CH4 uptake during spring freeze-thaw cycles in the northern desert steppe in China.

For the first time the author compiles two geocryological annals: a simplified version for the late Cenozoic (last 3.5 mln years) and a more detailed one for the Neopleistocene (Brunes epoch, last 800 thousand years).

For segregation and injection processes of water transfer a unique equation system is suggested, allowing calculation of characteristics of ice accumulation and freezing layer deformation. The system includes balance relations for heat and mass of water and frame on the freezing front. Moisture flows are determined for every mechanism with the use of additional relations. For a segregation mechanism of ice accumulation, the model suggested allows one to predict regularities of surface foundation deformations. For the injection mechanism, the share of mineral component content in forming freezing structures is calculated. It is shown that for this mechanism there is the critical value of moisture flow the exceeding of which results in pure ice formation.

The reaction of an ice complex on large-scale warming in the late Pleistocene-Holocene interval is considered. It is shown that erosion-thermokarst dismembering of an ice complex is determined by the totality of properties of the landscape and its components change after climate warming. On the background of degradation tendencies in definite conditions (ice complex outliers) there are phenomena of the stabilized aggradational type--formation of a protective layer.

Studies of anthropogenic pollution of geosystems in the Yenisei and Pechora River deltas from global and regional sources are presented. The level of pollution by radionuclides and heavy metal of plants, soils and natural waters is evaluated by the method of landscape-geochemical profiling of delta island and coastal sectors at different distances from the sea water area. Local contamination of flood plains on account of river transportation of cesium radioisotope from the Krasnoyarsk Mining and Chemical Enterprise is confirmed for the Yenisei River. On terraces and interfluves of the Yenisei's lower reaches the tendency for an increase of copper and nickel concentration in mosses and willow leaves when approaching the Norilsk plant is revealed. For Pechora River's lower reaches atmospheric contamination by Cs-137 on a global level is revealed. In 3 km lower than Naryan-Mar City in Pechora waters increased content of copper and zinc is found.

The necessity for construction of new ontological approaches is illustrated by a series of actual but previously poorly discussed manifestations of the cryosphere--from the first stages of the universe's development to the origin and evolution of life on Earth.

The biogeochemical structure of Yamal Peninsula landscapes is analyzed. The microelement composition of various-type soils is determined. Concentration of elements necessary for plant feeding is evaluated. The influence of two factors--geochemical activity of phytobiota and concentration of biogenic elements--on cryogenic landscapes stability is concluded. The first factor stabilizes material composition of landscape and manifests mostly in zonal geosystems. The velocity of vegetation regeneration after technogenic disturbances depends on the second factor, and azonal soils are most provided by elements of mineral feeding.

Problems of identification of subaqueous permafrost on the Kara Sea shelf are considered on the basis of identification of seismoacoustic markers in the seismoacoustic section. The presence of subaqueous permafrost is established in the southeastern Kara Sea and Yamal Shelf up to 120 m depth. The presence of frozen deposits at great depths is most likely exclusion and can be explained by descending neotectonic movements. A map of the Kara Sea subaqueous permafrost occurrence is compiled and a corresponding database on conditions of their location is developed. It is established that the cover of subaqueous permafrost lay at the depth 5-60 m lower than the sea floor surface. The maximal of occurrence is at the depth of cover lying 10-20 m from the bottom surface. A suggestion on the paragenetic relation between structures of gas seepage and subaquatic permafrost is stated.

Peculiarities of application of seismic methods for studying a seismogeocryological section are considered. These features are determined by specific features of a wave seismic field in frozen rock mass. The conclusion on the effectiveness of using a transverse wave of horizontal polarization for studying the superfrozen taliks and features of frozen rock structure is made. For estimation of properties and state of permafrost it is necessary to use information on velocity of propagation of longitudinal and transverse waves.

Mound congelation in the mountains of Altai, Kazakhstan, Mongolia, and China is a known phenomenon. In the regions with seasonal and long-term cryogenesis the artificial constructions with geometric forms cannot always be distinguished from natural formations. Increased ice content of rocks, vertical orientation of blocks, distinctions of color and structure of deposits which are characteristic for filling burial hollows and chambers are revealed under the mounds in northwestern Mongolia. It is established that anthropogenically undisturbed rocks under a mound lost natural color and structure due to cryogenic blowing up and weathering. High ice content of permafrost cryogenic eluvium of rocks, intense cryogenic fragmentation and sorting of large conglomerates are the result of local watering of seasonally thawed layer under the mound and occurred 3 thousand years after its construction.

New, previously not noted forms of layered buried ices were opened on the high Lena-Amga Plain during drilling in some points on watershed sites (absolute marks 220-250 m), which belong to a traditionally identified ice complex. Three isolated intervals of the presence of firn snow with different crystallization degree were revealed here under repeated-vein ice occurring in 2.5-5.0 m range: the upper one (12.0-17.0 m), middle (23.3-24.5 m), and lower (33.6-39.0 m). Between the firn horizons the formation of syngenetically frozen alluvium represented by uliginous and sandy aleurites is found.

It combines distant methods with ground route and instrumental (automated) observations and geoinformation cartography. Series of cartographic models is created, demonstrating the clear relation of local level geosystems with peat thickness and thawing depth. New indicators of temperature regime of permafrost are obtained.

The results of long-term monitoring of western Yamal seashore dynamics are presented: average multi-annual rate of shore recession in the Marre-Sale region is about 1.7 m/year (maximal is 3.3 m/year, and minimal 0.5 m/year). It is established that deformation of beach and underwater shore slope on the sections of thermoerosion shores development reaches 0.7 m and may have diverse signs. First quantitative evaluations of maximal deformations of marine accumulating surfaces are obtained. They are about 0.3 m.

Export of dissolved carbon from watersheds of the central Siberian Plateau: Doklady Earth Sciences, 441(1), p. 1568-1571, illus. incl. 2 tables, 15 ref., November 2011.
The influence of climatic and forest conditions on space and time variations in the concentrations and export of two forms of dissolved carbon (DOC) and dissolved inorganic carbon (DIC) in rivers of the Central Siberian cryolithic zone (Yenisei River basin) draining territory characterized by relatively homogeneous composition of parent rocks was analyzed. Rivers of the northern (Tembenchi and Kochechum rivers), central (Nidym River), and southern parts (Lower Tunguska and Podkamennaya Tunguska rivers) of the Central Siberian Plateau traps were selected as objects of investigation. Along with growth of the water flow rate, increase in the productivity and reserves of carbon in the biogeocenosis of the cryolithic zone leads to significant (more than twice) increase in export of terrigenous DOC and DIC to the hydrographic network.

Mean residence time of O horizon carbon along a climatic gradient in Scandinavia estimated by 14C measurements of archived soils: Biogeochemistry (Dordrecht), 104(1-3), p. 227-236, 2 tables, sketch map, 31 ref., July 2011.
We used two datasets of 14C analyses of archived soil samples to study carbon turnover in O horizons from spruce dominated old-growth stands on well-drained podzols in Scandinavia. The main data set was obtained from archived samples from the National Forest Soil Inventory in Sweden and represents a climatic gradient in temperature. Composite samples from 1966, 1972, 1983 and 2000 from four different regions in a latitude gradient ranging from 57 to 67°N were analysed for 14C content. Along this gradient the C stock in the O horizon ranges from 2.1 kg m-2 in the north to 3.7 kg m-2 in the southwest. The other data set contains 14C analyses from 1986, 1987, 1991, 1996 and 2004 from the O horizons in Birkenes, Norway. Mean residence times (MRT) were calculated using a two compartment model, with a litter decomposition compartment using mass loss data from the literature for the three-first years of decomposition and a humus decomposition compartment with a fitted constant turnover rate. We hypothesized that the climatic gradient would result in different C turnover in different parts of the country between northern and southern Sweden. The use of archived soil samples was very valuable for constraining the MRT calculations, which showed that there were differences between the regions. Longest MRT was found in the northernmost region (41 years), with decreasing residence times through the middle (36 years) and central Sweden (28 years), then again increasing in the southwestern region (40 years). The size of the soil organic carbon (SOC) pool in the O horizon was mainly related to differences in litter input and to a lesser degree to MRT. Because N deposition leads both to larger litter input and to longer MRT, we suggest that N deposition contributes significantly to the latitudinal SOC gradient in Scandinavia, with approximately twice as much SOC in the O horizon in the south compared to the north. The data from Birkenes was in good agreement with the Swedish dataset with MRT estimated to 34 years. Copyright 2010 Springer Science+Business Media B.V.

Extremely ice-rich syngenetic permafrost, or yedoma, developed extensively under the cold climate of the Pleistocene in unglaciated regions of Eurasia and North America. In Alaska, yedoma occurs in the Arctic Foothills, the northern part of the Seward Peninsula, and in interior Alaska. A remarkable 33-m-high exposure along the lower Itkillik River in northern Alaska opened an opportunity to study the unmodified yedoma, including stratigraphy, particle-size distribution, soil carbon contents, morphology and quantity of segregated, wedge, and thermokarst-cave ice. The exposed permafrost sequence comprised seven cryostratigraphic units, which formed over a period from >48,000 to 5,000 14C yr BP, including: 1) active layer; 2) intermediate layer of the upper permafrost; 3-4) two yedoma silt units with different thicknesses of syngenetic ice wedges; 5) buried peat layer; 6) buried intermediate layer beneath the peat; and 7) silt layer with short ice wedges. This exposure is comparable to the well known Mus-Khaya and Duvanny Yar yedoma exposures in Russia. Based on our field observations, literature sources, and interpretation of satellite images and aerial photography, we have developed a preliminary map of yedoma distribution in Alaska.

The Holocene thermal maximum and late-Holocene cooling in the tundra of NE European Russia: Quaternary Research, 75(3), p. 501-511, illus. incl. 3 tables, sketch map, 94 ref., May 2011.
To investigate the Holocene climate and treeline dynamics in the European Russian Arctic, we analysed sediment pollen, conifer stomata, and plant macrofossils from Lake Kharinei, a tundra lake near the treeline in the Pechora area. We present quantitative summer temperature reconstructions from Lake Kharinei and Lake Tumbulovaty, a previously studied lake in the same region, using a pollen-climate transfer function based on a new calibration set from northern European Russia. Our records suggest that the early-Holocene summer temperatures from 11,500 cal yr BP onwards were already slightly higher than at present, followed by a stable Holocene Thermal Maximum (HTM) at 8000-3500 cal yr BP when summer temperatures in the tundra were ca. 3°C above present-day values. A Picea forest surrounded Lake Kharinei during the HTM, reaching 150 km north of the present taiga limit. The HTM ended with a temperature drop at 3500-2500 cal yr BP associated with permafrost initiation in the region. Mixed spruce forest began to disappear around Lake Kharinei at ca. 3500 cal yr BP, with the last tree macrofossils recorded at ca. 2500 cal yr BP, suggesting that the present wide tundra zone in the Pechora region formed during the last ca. 3500 yr.

Slope instabilities in the central Southern Alps, New Zealand, are assessed in relation to their geological and topographic distribution, with emphasis given to the spatial distribution of the most recent failures relative to zones of possible permafrost degradation and glacial recession. Five hundred nine mostly late-Pleistocene- to Holocene-aged landslides have been identified, affecting 2% of the study area. Rock avalanches were distinguished in the dataset, being the dominant failure type from Alpine slopes about and east of the Main Divide of the Alps, while other landslide types occur more frequently at lower elevations and from schist slopes closer to the Alpine Fault. The pre-1950 landslide record is incomplete, but mapped failures have prevailed from slopes facing west-northwest, suggesting a structural control on slope failure distribution. Twenty rock avalanches and large rockfalls are known to have fallen since 1950, predominating from extremely steep east-southeast facing slopes, mostly from the hanging wall of the Main Divide Fault Zone. Nineteen occurred within 300 vertical metres above or below glacial ice; 13 have source areas within 300 vertical metres of the estimated lower permafrost boundary, where degrading permafrost is expected. The prevalence of recent failures occurring from glacier-proximal slopes and from slopes near the lower permafrost limit is demonstrably higher than from other slopes about the Main Divide. Many recent failures have been smaller than those recorded pre-1950, and the influence of warming may be ephemeral and difficult to demonstrate relative to simultaneous effects of weather, erosion, seismicity, and uplift along an active plate margin.

Simulating unsteady flow, anabranching, and hyporheic dynamics in a glacial meltwater stream using a coupled surface water routing and groundwater flow model: Water Resources Research, 47(5), Citation W05530, illus. incl. 3 tables, 48 ref., 2011.
Flooding affects ecosystems by transporting water and solutes across aquatic-terrestrial interfaces, removing nutrient and organic substrate limitations, and spurring biogeochemical activity. Few studies have considered the influence of flooding on surface water-groundwater interactions. This research examines the temporally variable water storage and exchange in a stream in the McMurdo Dry Valleys (MDV) of Antarctica, where diel flood pulses occur due to glacial melt. Several MDV streams display truncated discharge peaks, suggesting water storage between the source glacier and the gauging station. We tested the hypothesis that stream braids and subsurface water storage contribute to the difference between glacial melt and stream outflow hydrographs by constructing a coupled surface water routing and subsurface water flow model. This model routes water into stream braids at high flows and allows this water to infiltrate and return to the stream via subsurface flow paths as flows recede. Our simulation demonstrates the importance of surface-subsurface water interactions in controlling the hydrograph shape. Maximum simulated discharge was sensitive to storage parameters including aquifer depth and the flooding threshold, while minimum discharge was sensitive to hydraulic conductivity. Subsurface storage volume varied by 38% over a diel cycle and stream-subsurface exchange rates varied from 0 to 0.19 m3 h-1 m-1, with exchange from the stream to the subsurface during high flows, and vice versa at low flows. These results underscore how unsteady flow can increase hyporheic interactions and ecosystem productivity, and provide support for maintaining natural stream morphology and flow regimes.

A modeling data set (meteorological forcing data, geographic information system data, and validation data) is presented for water years 1984 through 2008 for a snow-dominated mountain catchment. The forcing data include hourly precipitation, wind speed and direction, air and soil temperature, relative humidity, dew point temperature, and incoming solar and thermal radiation from two sites. Validation data include stream discharge, snow water equivalent, snow depth, soil moisture, and groundwater elevation. These data will improve the development, testing, and application of the next generation of hydrologic models.

Relationship between specific surface area and the dry end of the water retention curve for soils with varying clay and organic carbon contents: Water Resources Research, 47(6), Citation W06522, illus. incl. 2 tables, 46 ref., 2011.
Accurate description of the soil water retention curve (SWRC) at low water contents is important for simulating water dynamics and biochemical vadose zone processes in arid environments. Soil water retention data corresponding to matric potentials of less than -10 MPa, where adsorptive forces dominate over capillary forces, have also been used to estimate soil specific surface area (SA). In the present study, the dry end of the SWRC was measured with a chilled-mirror dew point psychrometer for 41 Danish soils covering a wide range of clay (CL) and organic carbon (OC) contents. The 41 soils were classified into four groups on the basis of the Dexter number (n = CL/OC), and the Tuller-Or (TO) general scaling model describing water film thickness at a given matric potential (<-10 MPa) was evaluated. The SA estimated from the dry end of the SWRC (SA_SWRC) was in good agreement with the SA measured with ethylene glycol monoethyl ether (SA_EGME) only for organic soils with n > 10. A strong correlation between the ratio of the two surface area estimates and the Dexter number was observed and applied as an additional scaling function in the TO model to rescale the soil water retention curve at low water contents. However, the TO model still overestimated water film thickness at potentials approaching ovendry condition (about -800 MPa). The semi-log linear Campbell-Shiozawa-Rossi-Nimmo (CSRN) model showed better fits for all investigated soils from -10 to -800 MPa and yielded high correlations with CL and SA. It is therefore recommended to apply the empirical CSRN model for predicting the dry part of the water retention curve (-10 to -800 MPa) from measured soil texture or surface area. Further research should aim to modify the more physically based TO model to obtain better descriptions of the SWRC in the very dry range (-300 to -800 MPa).

Accelerated release of carbon from soils is one of the most important feedbacks related to anthropogenically induced climate change. Studies addressing the mechanisms for soil carbon release through organic matter decomposition have focused on the effect of changes in the average temperature, with little attention to changes in temperature variability. Anthropogenic activities are likely to modify both the average state and the variability of the climatic system; therefore, the effects of future warming on decomposition should not only focus on trends in the average temperature, but also variability expressed as a change of the probability distribution of temperature. Using analytical and numerical analyses we tested common relationships between temperature and respiration and found that the variability of temperature plays an important role determining respiration rates of soil organic matter. Changes in temperature variability, without changes in the average temperature, can affect the amount of carbon released through respiration over the long-term. Furthermore, simultaneous changes in the average and variance of temperature can either amplify or dampen the release of carbon through soil respiration as climate regimes change. These effects depend on the degree of convexity of the relationship between temperature and respiration and the magnitude of the change in temperature variance. A potential consequence of this effect of variability would be higher respiration in regions where both the mean and variance of temperature are expected to increase, such as in some low latitude regions; and lower amounts of respiration where the average temperature is expected to increase and the variance to decrease, such as in northern high latitudes.

Evaluation of the heat pulse probe method for determining frozen soil moisture content: Water Resources Research, 47(5), Citation W05544, illus. incl. 1 table, 47 ref., 2011.
Heat pulse probes (HPP) have been widely utilized to determine soil thermal properties and water content in unfrozen soils; however, their applications in frozen soils are largely restricted by phase change and the presence of unfrozen water. This study explores the possibility of using HPP to determine total water content of frozen soils by (1) establishing the optimum heat applications to limit melting, (2) improving the mathematical representations for frozen conditions, and (3) evaluating the applicability of HPP methods under various temperature and moisture conditions. A custom-built HPP was tested at total moisture levels that varied from full saturation to oven dry and initial soil temperatures from 20°C to -11°C. The applied heat pulse durations varied from 8 to 60 s, with total heat strength varying from 100 to 2000 J m-1. Comparison of mathematical methods involved two analytical solutions and a one-dimensional finite difference numerical model. While both analytical methods assumed no phase change, the numerical model considered ice melting and unfrozen water. Conclusions include the following: (1) the numerical model with phase change is the only appropriate method to represent the temperature change curve once melting occurs; (2) below -4°C, ice melting could be limited, and measurement errors of total moisture content were within ±0.05 m3 m-3; (3) application of HPP between -2°C and 0°C is difficult because of the retarded response of probe temperature to changing moisture contents and heat applications; and (4) probe spacing is a sensitive parameter requiring calibration once reinstallation of the probe or the thawing and freezing process occurs.

Due to a lack of systematic observations, the intensity and volume of rock falls and rock avalanches in high mountain areas are still poorly known. Nevertheless, these phenomena could have burly consequences. To document present rock falls, a network of observers (guides, mountaineers, and hut wardens) was initiated in the Mont Blanc Massif in 2005 and became fully operational in 2007. This article presents data on the 66 rock falls (100 m3 ≤&eq; V ≤&eq; 50,000 m3) documented in 2007 (n = 41) and 2008 (n = 25). Most of the starting zones are located in warm permafrost areas, which are most sensitive to warming, and only four rock falls are clearly out of permafrost area. Different elements support permafrost degradation as one of the main triggering factors of present rock falls in high mountain areas. Copyright 2010 Springer-Verlag

Multidisciplinary studies conducted in Russian Karelia substantiated the existence of a major Baltic-Ladoga waterway in the Karelian Isthmus that emerged ca. 9500 cal BCE, and remained in action for ca. 7000 years. The predominant location of prehistoric sites in the catchment area indicates that this waterway effectively controlled the movements of hunter-gatherer groups during the greater part of the Holocene. A general increase of population density and sedentary behaviour, signalled by the beginning of intensive pottery-making at ca. 5560-5250 cal BCE, occurred in an environment of increased biodiversity and the establishment of mixed boreal - broad-leaved forests observable in the pollen records. The transgression of Lake Ladoga reached its peak between 1500 and 1000 BCE, resulting in the breakthrough of the Neva River and a general fall in the water level of the Ladoga-Volkhov-Ilmen hydrological system. The availability of low-lying fertile soils stimulated the rapid expansion of agriculture, recognized by the occurrence farming-related pollen and changes in the sedimentation, resulting in the rapid spread of farming communities.

The coastal area of western Norway is characterized by heathlands of Calluna vulgaris, developed and maintained through grazing by domestic animals and burning. Pollen diagrams from five sites (Vingen, Skatestraumen, Selja, Osneset, Gossen) are presented and the heathland development discussed. Soil, topography and cultural history differ between the sites, whereas the climate is relatively similar along the coast. The investigation shows presence of Calluna in forest openings from the Mesolithic, but cultural activity including grazing did not result in heathland development before 1300 cal. BC. The oldest heathland is found in an area of moraine and marine sand well suited for agricultural activity where heathlands developed as part of the farming economy. At sites with poorer soil, heathland development took place in the Iron Age and medieval time, as outfield pastures for farms located in some distance to the sites. By the medieval monastery at Selja, heathlands existed from the Late Iron Age and expanded into grasslands and cereal fields when the monastery was abandoned. The investigation illustrates the variation that exists in heathland development and the different factors that may cause the development. Until 1000 years ago, the coastal landscape probably held a mosaic of vegetation types; heathlands, grasslands, cultivated fields and forests.

Ground-source heat pumps (GSHP) represent an important technology that can be further developed by collecting data sets related to shallow thermal regimes. Computer programs that calculate the required lengths and configurations of GSHP systems use specific input parameters related to the soil properties to enhance the accuracy of models and produce efficient system designs. The thermal conductivity of sediments varies significantly depending on texture, bulk density, and moisture content, and it is therefore necessary to characterize various unconsolidated materials under a wide range of moisture conditions. Regolith texture data are collected during some installations to estimate thermal properties, but soil moisture and temperature gradients within the vadose zone are rarely considered due to the difficulty of collecting sufficient amounts of data. Six monitoring locations were chosen in Indiana to represent unique hydrogeological settings and glacial sediments. Trenches were excavated to a depth of 2 meters (a typical depth for horizontal GSHP installations) and sediment samples were collected at 0.3-meter intervals for a laboratory analysis of thermal conductivity, thermal diffusivity, bulk density, and moisture content. Temperature sensors and water-content reflectometers were installed in 0.3-meter increments to monitor changes in temperature and soil moisture with depth. In-situ thermal conductivity and thermal diffusivity were measured at 1.5-meters using a sensor that detects radial differential temperature around a heating wire. Micrometeorological data were also collected to determine the surface conditions and water budgets that drive fluxes of energy and moisture in the shallow subsurface. Preliminary results indicate that increases in water content can increase thermal conductivity by as much as 30% during wetting front propagation. Although there is a change in temperature associated with the infiltration of wetting fronts, thermal conductivity appears to be independent of soil temperature. By establishing continuous data sets, fluctuations in seasonal energy budgets and unsaturated zone soil moisture can be determined. This information can then be used to establish accurate end members for thermal properties and improve the efficiency of geothermal systems.

The map of moraines in Michigan has changed little since Leverett and Taylor's (1915) seminal publication. We report on the Port Huron and Lake Border moraines in northwestern lower Michigan and show evidence for significant changes to their originally mapped locations. The Port Huron moraine is a large accumulation of mostly sand and gravel that reaches altitudes over 320 m, 80 m above the adjacent valley to the west. As currently mapped however, the Port Huron moraine abruptly ends on the north side of the Manistee River valley. Older maps suggest that it continues to the southwest through series of small hills to Lake Michigan at Ludington. To the east, the older Lake Border moraine, much of which exceeds 400 m altitude, is mapped in contact with the Valparaiso/Charlotte interlobate moraine at the latter's northwest corner near Harrietta. It then curves southwest in a large reentrant that returns to the interlobate moraine 67 km to the south in Newaygo County. Recent mapping of deposits indicates that the existing ice-margins represented by these moraines are likely incorrect. Much of the Lake Border and interlobate moraines are glaciodeltaic sediment. At the maximum extent of the Lake Border glacier, a high level lake was bounded by older interlobate deposits to the south and the Saginaw lobe to the east. As the Lake Border glacier retreated, large deltas formed west of the Lake Border moraine, but were supplied by water and sediment from Saginaw lobe. The Port Huron moraine did not dam a similarly high level proglacial lake and is predominantly composed of glaciofluvial deposits. We present a more accurate position of the Port Huron moraine extending due south across the Manistee River where the Lake Border moraine is traditionally drawn. The Port Huron moraine then arcs to Lake Michigan in Oceana County where uplands are also composed of glaciofluvial deposits. The adjusted position of the Lake Border moraine is still in contact with the western edge of the interlobate moraine until the Lake-Newaygo County line where uplands composed of glaciodeltaic deposits are mapped. These reinterpreted positions also eliminate soil type disparities that cross the traditional moraine boundaries.

Glacial aquifer systems in the Midwestern Basin and Arches Region provide an abundant source of fresh water that is increasingly threatened by activities associated with industry, agriculture, urbanization, and growing populations. Sophisticated hydrogeologic models are needed to address complexity in the three-dimensional aquifer properties variability and contaminant plume morphology to effectively contain or remediate groundwater pollutants in these glacial aquifer systems. This presentation describes the use of hybrid models incorporating stochastic variability within a deterministic allostratigraphic framework to model spatial variability of physical hydrogeologic properties in a glacial aquifer system. The approach is illustrated with an example from the Pall Life Sciences (formerly Gelman Sciences) groundwater contamination site in Ann Arbor, Michigan. At the Pall Life Sciences site, wastewater containing 1,4-dioxane was discharged into unlined seepage lagoons and spray irrigated across a 15 acre field from 1967 to 1985. Plumes of 1,4-dioxane-contaminated groundwater have migrated several kilometers from the site in different directions through 80 m of underlying glacial drift. Because 1,4-dioxane is readily soluble in water and does not easily degrade or adsorb to soil particles, it provides a tracer-like record of solute transport. More than 130 monitoring wells and 20 extraction wells have been drilled to investigate and remediate 1,4-dioxane in the area. Today, remedial activities initiated more than 25 years ago continue along with efforts to characterize and model the aquifer system as the deepest known plume advances toward the Huron River through a groundwater Prohibition Zone established in 2005.

V. and Henderson, G. M. Speleothem record of permafrost in Siberia and aridity in Mongolia during the last 450 kyr [abstr.]: in Goldschmidt 2011 abstract volume, Mineralogical Magazine, 75(3), p. 2057, 2011. WWW. Meeting: Goldschmidt2011, Aug. 14-19, 2011, Prague, Czech Republic.
We have used speleothems from six caves along a north-south transect in Eastern Siberia and the Mongolian Gobi Desert (60°22'N - 42°50'N) to track the evolution of permafrost and desert aridity. The studied caves are located in various climate zones: from the southern boundary of continuous permafrost, through the discontinuous/island permafrost, to the dry Gobi Desert. More than 90 horizons of 22 speleothems were dated by U-Th method. The youngest speleothem age in the northernmost cave was 404 ± 32 kyr, corresponding to interglacial Marine Isotopic Stage (MIS) 11, while eleven other horizons in six speleothems from this cave were older than the ~500 kyr U-Th dating limit. These results suggest that MIS-11 in Eastern Siberia was warmer than today, causing brief permafrost degradation at 60°N, followed by re-establishment and continuous permafrost since then. Between 56°N and 52°N speleothem ages clustered into the warmest intervals of interglacial MIS-11, 9, 7, 5 and 1, showing intermittent melting of the permafrost. This data provides constraints on glacial-interglacial migrations of the southern boundary of continuous permafrost in Eastern Siberia during the last 450 kyr. No speleothem deposition younger than 500 kyr was found in the Gobi Desert, showing that arid conditions prevailed during this entire period. The year-round monitoring of d18O and dD values of cave water and atmospheric precipitation in the city of Irkutsk and nearby cave shows that d18O and dD values of rain and snow are in direct relationship with temperature throughout the year, and d18O and dD values of the cave water reflect the weighted annual average of precipitation. Ongoing work is making use of these observations to create stable isotope records of the Siberian speleothems.

12077881 Vereschagina, E. A. (Saint Petersburg State University, St. Petersburg, Russian Federation). Evaluation of contaminant transport parameters at Leningrad Atomic Power Plant drain area [abstr.]: in Goldschmidt 2011 abstract volume, Mineralogical Magazine, 75(3), p. 2080, 2011. WWW. Meeting: Goldschmidt2011, Aug. 14-19, 2011, Prague, Czech Republic.
The Leningrad Atomic Power Plant (Leningrad APP) drain area was studied. A hydrological study has been performed to demonstrate how contaminant transport proceeds in case of hypothetical disasters. Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model was chosen for the simulation of radionuclide and chemical transport. GSSHA is a physics based, fully distributed, hydrologic and sediment transport model. The distributed nature of the model confers significant potential advantages for the analysis of non-point source pollutant fate and control. Precipitations falling on the watershed contain specified concentrations of contaminants for hypothetical disasters at Leningrad APP. As rainfall accumulates on the land surface, ponded surface water infiltrates, providing a source of contaminants into the soil column, and move as surface runoff to adjacent territory. Concentrations of contaminant are affected by decay and transformations. The most part of the water ponded on the land surface infiltrates, removing contaminants. Water that infiltrates is assumed to contain the same concentration of dissolved contaminants as the ponded water. Infiltration was simulated using traditional Hortonian Green and Ampt (GA) approach. Additionally, field experiments for testing the values of the Green and Ampt infiltration equation parameters were done for prevailing at the drain area soil types. The determined parameters were the effective capillary suction and the effective hydraulic conductivity. Comparison of the model outputs with the experimental data indicates that the model can successfully describe cumulative infiltration in different soil types and contaminant transport.
