THERMAL ASPECTS OF N.A. TSYTOVICH PRINCIPLE OF WATER AND ICE EQUILIBRIUM STATE IN FROZEN GROUND
The applicability of the Stephen problem solutions for permafrost dynamics modeling is discussed using N.A. Tsytovich principle of water and ice equilibrium state in frozen grounds. The main external impacts controlling equilibrium, relationships between equilibrium dynamics and thermal processes in ground, possibilities of mathematical modeling of permafrost dynamics are reviewed. The dynamics of equilibrium state in saline ground is discussed using results of permafrost investigations on Yamal Peninsula and Laptev Sea shelf. It is revealed that the cryopeg temperature in equilibrium state is equal to its initial freezing point, the ice-bonded permafrost may contain cryopeg and preserve permeability, the cryopeg boundary may not coincide with the phase boundary. Free-salined permafrost on the shelf flooded by the sea undergoes fast salinization and physicochemical thawing at negative temperature. The thawing is accompanied by temperature lowering due to latent heat absorption. The ice content in salined permafrost on shelf is changing in space gradually without a clear phase boundary. It is revealed that solutions of Stephen problem are unacceptable for shelf permafrost modeling.

MASSIVE ICE BEDS IN THE MARRESALE POLAR STATION AREA (WESTERN COAST OF THE YAMAL PENINSULA)
When studying the data and materials on massive ground ice bodies in the outcrops of MarreSale Cape, we focused our scientific interests primarily on the analysis of the salt-ionic composition and mineralization of ice masses composing the lower massive ice bed in the frozen saline marine sediments, and of the upper massive ice bed, sitting in the stratum of the frozen nonsaline continental deposits. The identity of salt-ionic composition of ice masses in the upper and lower parts of the massive ice beds, as well as the kinship of the hydrochemical characteristics of massive ice beds and lake-waters have been ascertained upon comparing the mineralization and chemical composition of massive ice beds and natural waters. The research results and findings are listed that: 1) both the upper and lower massive ice bed were fed by lake-waters; 2) the formation of the lower massive ice bed in the frozen saline marine sediments proceeded with out seawater input; 3) the lower massive ice bed accumulation commenced and was taking place already in the permafrost, long after the marine regression was completed.

SEISMIC CRITERIA FOR INDENTIFYING FROZEN SOIL
Unfrozen and frozen soils of sand to clay grain sizes can be discriminated using seismic criteria, especially Poisson's ratio. According to the available published evidence and experimental results collected for years in the areas of Arctic West Siberia and European North, Poisson's ratios (μ) in the range 0.45–0.46 mark the boundary between frozen and unfrozen states of water-saturated soils. The values μ > 0.46 and μ < 0.45 correspond, respectively, to unfrozen and frozen soils, irrespective of their composition, temperature and salinity. Poisson's ratio is thus an additional permafrost proxy and an effective tool of geocryological studies.

THE INFLUENCE OF GAS-BEARING STRUCTURES ON THE CRYOGENIC STRATA THICKNESS IN YAMAL AREA
Cryogenic strata of the north of West Siberia is regarded as a unified cryogenic formation of the Middle and Late Neopleistocene and Holocene formed in the aftermath of the of transgression–regression rhythmic events in the polar basin in the course of cyclic changes in the harsh climate. With reliance on the current data, our research findings have given some insights into the permafrost developing in the subaerial and submarine environments, and into the gas accumulation affecting the cryogenic strata thickness in the section and within the extent of the gas-bearing structures.

ICE THICKNESS, VOLUME AND CURRENT CHANGES OF THE SARY-TOR GLACIER AREA (AK-SHYIRAK MASSIF, INNER TIAN SHAN)
In the paper we present and discuss results of radio-echo sounding and ice thickness modeling of Sary-Tor Glacier (Ak-Shyirak massif, Inner Tian Shan). Ability for correct assessment of regional glacier volume in Tian Shan is limited due to the small amount of direct ice thickness measurement data. 17 km of ice thickness measurements tracks were done on 18–20 May, 2013 using monopulse VIRL-6 GPR with central frequency 20 MHz. Maximum measured ice thickness was 159 m, whereas average thickness was 51 m. Detailed ice thickness and bedrock topography maps were compiled for Sary-Tor. The glacier volume was defined as (0.126 ± 0.001) km3. In addition, ice volume was calculated using the Glab-Top model calibrated by direct data and volume-area scaling. Both approaches could be used to determine the ice volume of the Sary-Tor glacier with high accuracy. The Sary-Tor glacier area shrinkage rate in 2003–2012 slightly decreased compared to 1977–2003.

ISOTOPE COMPOSITION OF PINGO ICE CORE AT EVOYAKHA RIVER VALLEY, NORTH-WEST SIBERIA
Ice core of Pestsovoye pingo in the Evoyakha River valley in North-West Siberia has been studied. Thickness of the pingo ice is more than 15 m. The δ18О value of the pingo ice varies from –11.6 to –15.8‰, δD from –93.2 to –123.0‰. Comparison with isotope data of ice core of Weather pingo (Alaska) has been carried out. In Weather pingo ice δ18О values range from –15.5 to –22‰, δD values change from –132 to –170‰. Both isotope profiles of pingo ice are contrasting and arcuate-shaped as a result of isotope fractionation during freezing of sub-pingo waters in closed system. Fractionation leads to isotopic contrast of ice: by 4-6‰ of δ18О and by 20-25‰ of δD values. Radiocarbon dating of the covering peat at Pestsovoye pingo have evidenced that the heaving had occurred at two stages. At the first stage the heaving began about 5 kyr BP in distal part of the mound. At the second stage about 2.5 kyr BP the heaving recommenced actively in the central part of the pingo. The heaving rate was very high – more than 2-3 cm per year. As a result a pingo of 17 m high has been formed.

RESULTS OF COMPLEX STUDYING THE KARA SEA SHORE DYNAMICS IN THE AREA OF THE METEOROLOGICAL STATION MARRE-SALE USING THE GIS-TECHNOLOGIES
The results of 44-year integrated observations of the Kara Sea shore dynamics in the area of the VSEGINGEO Marre-Sale Station have been presented. The multi-year on-land registration of the sea shoreline retreat to the distance of 4.5 km in combination with detailed drilling of the shore zone and with the use of remote research methods have enabled the authors to reveal the basic regularities in the manifestation and dynamics of destructive and accumulative processes within this area. The use of GIS-technologies have allowed to obtain for the first time the objective qualitative data about the shoreline retreat and bottom areas of the shore cliffs (average and interval values) both for the total period of observation and particular periods.
The real state of the shoreline in the station area and its dynamics are clearly registered by large-scaled aerial photos and video-images taken in different years.
Data of the remote sounding of the Earth (RSE) in the station area demonstrate the active manifestation of the geodynamic processes in the Marre-Yakha river mouths.

INFLUENCE OF LOCAL FACTORS ON THE STRUCTURE OF PERMAFROST, ZHOSALYKEZEN PASS (NORTH TIEN SHAN)
The results of studies of mountain permafrost of Alpine type by the methods of thermometry and geoelectrical survey are presented. The influence of natural and anthropogenic local factors on the structure of permafrost is demonstrated using the geoelectric models. Such factors include the exposition of the slope, the tectonics, the warming and cooling effects of the foundations of buildings. Changing slope exposure is expressed on geoelectric models by the decreasing of resistivity of high-resistance horizon, the violation of its continuity and the decreasing of its thickness. In the area of faults the discontinuous or island character of high-resistance horizon (permafrost) is observed. During the seismic events the temperature of rocks increases here up to the positive values. According to geophysical data, the formation of taliks occurs in the basis of deformed buildings, in the places of accumulation of snow at snow barriers and under the sites with asphalt covering.

2. Main research results
1) A mathematical model was developed simulating coastal and nearshore permafrost conditions in the eastern sector of the Russian Arctic over the last 4 ky (Fig. 1). The model, based on observations of thermo-abrasional coastal retreat along the Arctic seas, as well as on drilling data from the Laptev Sea shelf obtained in 2003-2014, helps facilitate a better understanding of the dynamics of subsea permafrost boundaries in the Arctic shelf (PI: Dr. Mikhail Grigoriev and Dr. Sergey Razumov).

2) The Late Holocene glacial-cryogenic complexes, as well as the recent glacial deposits in the Suntar-Khayata Range, eastern Yakutia, were studied. The isotopic composition of ice in the glacial-cryogenic complexes suggests the monsoon moisture origin from the Okhotsk Sea, casting doubt on the prevailing hypothesis that the westerly and Arctic transport of air masses played a primary role during the Late Pleistocene and Holocene (PI: Dr. Aleksey Galanin) (Fig. 2).

3) An engineering-geological map of the Republic of Sakha/Yakutia was compiled at a scale of 1:1,500,000-scale (edited by L.N. Kovalev and R.V. Zhang, compiled by V.B. Spektor, Ya.I. Torgovkin, A.A. Shestakova, V.V. Spektor, L.D. Ivanova and B.M. Kozmin). The map, first in its kind for the region, provides a scientific foundation for planning of economic development, construction of large engineering projects, and environmental protection in the vast Arctic region of Russia. The map shows geological, geocryological, hydrogeological and seismic conditions, as well as geotechnical hazards.

4). As part of its basic fundamental research theme, the Institute conducted investigations on seven projects funded by grants from the Russian Foundation for Basic Research, three integrated projects, and several contracts totaling over 35 mln. rubles. The latter mainly included geocryological site investigations in various areas of the East Siberian permafrost region, as well as determinations of physical, mechanical and chemical properties of soils for large engineering projects.
5). An important event for geocryology in 2014 was the 10th International Symposium on Permafrost Engineering held from 22-24 August 2014 in Harbin, China under the theme "Challenge and Adaption of Permafrost Engineering to a Changing Climate". This symposium, co-organized by MPI, brought together about 300 researchers from six countries (Russia, China, USA, Canada, Japan, and Turkey), including 21 delegates from MPI. The symposium stressed that understanding the thermal state of permafrost and the development of worldwide standards for permafrost monitoring in a changing climate remain the priority tasks for engineering geocryology. Papers submitted to the symposium were published in special issues of the journals, Sciences in Cold and Arid Regions (Volume 6 Issue 4 August 2014 and Volume 6 Issue 5 October 2014), Journal of Engineering of Heilongjiang University (Volume 5 No. 3 September 2014) and Journal of Glaciology and Geocryology (Volume 36 No. 4 August 2014). The next, 11th symposium on permafrost engineering was decided to be held in 2017 in Magadan, Russia.

Cryolithology and Glaciology Department, Geographical Faculty, Lomonosov Moscow State University
In 2014 Department of Cryolithology and Glaciology undertaken fundamental research on the impact of the cryospheric objects change on environment and society.
The department developed several conceptual rules for assessment and prediction of cryo-ecologicalconditions under development of crylithozone in terms of (a) landscape resistance to negative cryogenic processes, (b) type and (c) intensity the technogenic load (Monography: Tumel' N., Zotova L. Geoecology of Cryolithozone: textbook. – Moscow, Faculty of Geography, MSU, 2014, 244 p.). Researchers formulated definitions and methods of assessment; detected main lithocryogenic and biotic factors of landscape resistance to cryogenic processes in different environmental conditions; provided a procedure of their comparison in order to calculate integral indexes with further ranking by sensitivity to development, and to make GIS-maps then.
Researchers made the "Map of the ground ice of the cryolithozone of Russia", in which they successfully linked distribution of various means of ice with tectonic development of the Russian Arctic (Bulletin of the MSU, 2014; Geography, Environment..., 2014).
The department continued monitoring of the active layer dynamics on two sites – near Talnakh (south of the Taymir peninsula) and in Lorino (settlement on Chukotka). The monitoring was started in 2004 under the International program CALM - Circumpolar Active Layer Monitoring. Last measurement reflects the reaction of frozen ground to relatively cold, but rainy summer 2014: this year around Talnakh mean depth of thaw increased by 20%. It is 20% bigger then measured in extremely hot (but abnormally dry!) summer 2013.
Using calculations and field observations, we assessed the efficiency of different managerial strategies for thermal regime of frozen foundations in built-up areas. It is found, that the most conventional and popular way to decrease temperature – arrangement of cold ventilated cellars – is not comprehensive in regions with continental climate and scarce snow cover (e.g. Yakutia, inner areas of Magadan region, etc.). The department analyzed permafrost temperature change in dependence of density, structure and (it is critical) – the age of housing. In the areas of "old" development, regional peculiarities form significant differences in temperature trends (examples – centers of Dudinka, Salekhard, Khatanga, etc.). In general, degradation prevails. Temperature decrease can be measured due to a strong anthropogenic salinization, but it is not increasing bearing capacity of refrigerated foundations – as adfreezing force declines (EUCOP, 2014).
In the changing climate and cryosphere 62 million square kilometers are covered by ice, seasonal and perennial snow cover. Some years this square varies, as well as it changes through the cycle of seasons (Ivanov M., Glaciological symposium "The role of snow and ice in people's lives", The World Snow Forum, Novosibirsk, 2014).
The department studied differences and similarities in formation of "alpine" and "siberian" types of glaciers. First established, that they have no qualitative differences, existing differences (the role of infiltrationcongelation ice in their composition) have quantitative nature.
In July 2014 in Igarka and Norilsk region were held regular International field student's courses on permafrost, which was attended by younglings from Russia, USA, Great Britain, Germany and Norway (courses are conducted by docent of Lomonosov Moscow State University Valery Grebenets and professor of The George Washington University Dmitry Streletsky).
Geocryology Department, Geology Faculty, Lomonosov Moscow State University
Geocryology department of Moscow University has finished its long-term work on a new thermal computer software for 3D permafrost forecast. First version of the digital permafrost map of Russian Federation (scale 1: 2 500 000) was done. The department was involved in projects related study of the offshore permafrost in Laptev and Kara sea. Geophysics was applied to estimate permafrost table and depth in the Arctic basin. Investigations on gas hydrates in Western Siberian permafrost were continued, and new data has been received for its distribution. as well as the gas content for offshore marine frozen deposits in the Eastern Arctic. A study the thermal mode, soils thermal properties and mechanisms of coastal erosion in the Baydara Bay (Kara sea coast) was done including coastal soil temperatures, thermal conductivity and other soil properties. A role of snow fields in the thermal erosion has been shown. Phase and salts concentration equilibrium was studied in Yamal peninsula permafrost in a range of temperatures. Deformations of thawing icy clay soils ware investigated in laboratory conditions for Western Siberian marine and alluvial deposits. A number of case studies in permafrost regions with oil and gas companies were also done. A master program specializing in permafrost studies in English has been open in 2014 in the department for the foreign students.

Mining-Geological Joint-Stock Company MIREKO
MIREKO company continues 30-45-year permafrost monitoring covering several main landscapes of European North of Russia. The main result of observations in 2014 – preservation of long-term trend of permafrost degradation. The lowering of level of underground waters, resulted from 21-year mine drainage, irregularly affects primary hypsometrical level of permafrost roof and foot. Degradation and progression of permafrost are observed depending to the thickness of technogenic aeration zone. The observations will be continued. Please see below top priorities in permafrost research that we suggested.
1. "Approbation of methodology of middling-term forecast of permafrost parameter The our methodology provides for the possibility of forecast of permafrost temperature, appearance and increasing thickness of closed taliks, thermokarst subsidence and cryogenic heaving of sediments for the nearest 15-20 years. The methodology was received by Customer – «Rosnedra», and then it was published in «Prospecting and Protection of Mineral Resources» Journal, No 7, 2009; its developments and details were reported at the Third European Conference on Permafrost. Longyearbyen, Svalbard, Norway. «Permafrost Monitoring in Northwestern Russia and a Methodology of the mid-Range Projections of Its Past and Future Degradation in Natural Conditions». N.Oberman, I.Derevyanko, V.Romanovsky, H.Vanhala, P.Lintinen.
Considering the practical importance of such forecasts for stable functioning of industrial and civil buildings in the permafrost area, we think that the evaluation of forecast accuracy and improving it, if necessary, is very timely. Such an evaluation compares the forecasted values of parameters with their actual field measurements. To perform this task we have all necessary conditions: 2 acting and 4 preserved geocryologic stations located in six different landscapes and with long-term, 30-45 years, observation periods, and also appropriate personnel. MIREKO Mining Geological Company is ready to solve this task.
2. "Evaluation of dynamics of icings of moderate and south type in the Urals and their There are more than 200 large and extra-large icings in Polar and Subpolar Urals. In the very beginning of 1980s they were observed by inspection, and some of them – by stationary observations (company MIREKO). Modern observations by inspections in some typical icings in low- and midmountains will allow to see their dynamics, connection with climate changes and to forecast their development in future.
3. Permafrost map of Pechora-Ural region, scale 1:1500000. The permafrost of European North is the most vulnerable in comparison to the Western Siberia, Yakutia to the influence of climate change, and also – of oil-gas, mining industries, due to specific climate, permafrost and hydrogeological conditions. Recently a lot of new permafrost information was accumulated. All this motivates to renew the existing permafrost maps. The suggested map could be prepared in two sheets variant: Permafrost maps of 2016 and Forecast permafrost map as of 2030. MIREKO company with its more than 40-year experience of permafrost mapping of the region (including a number of published maps) can claim to perform this object.
Joint-Stock Company "Fundamentproekt"
JSC "Funadmentproekt" carried out complex research and elaborated the methodological principles and methods of the creation of new geotechnical cartographic models into structure of the GIS engineering geocryological and permafrost cartographic models. Creation of the geotechnical cartographic models is considered as a method of adaptation and practical using of a geocryological investigation for the design and construction in the Permafrost area and in complex environment.
Completed the set of laboratory researches of frozen grounds creep properties. The frozen grounds testing made by USA standard (ASTM 5520) and Russian standard (GOST 12248-2010). It can be set that a direct correlation of frozen grounds creep properties obtained with the methods of test processing by ASTM 5520 and by GOST 12248-2010 cannot be. But tests made by ASTM 5520 standards can be handled by GOST 12248-2010. In this case, creep frozen grounds properties close to those obtained in the tests made and handled according to GOST 12248 In this case, creep frozen grounds properties close to those obtained in the tests made and handled according to GOST 12248.
Sergeev Institute of Environmental Geoscience, RAS (Moscow)
