of the probable detection area of oil pollution on the sea surface||5|
The method of estimation of the probable detection area of oil pollution on the sea surface is proposed. The mathematical formulation of the problem for the instant and continuous oil dumping is submitted, and it is proposed the numerical method of its decision. Results of the calculations for the Barents Sea are presented. The proposed method is useful for the information support of the accidents involving oil spill on the sea surface, regardless of the specific model for simulation of the oil pollution spreading.
Keywords: mathematical modeling, oil spills in sea, detection of oil spill area.

based on orbital tuning of air content records: a case study
of the Dome Fuji (Antarctica) ice core||14|
We have further elaborated an algorithm for implementing a new method of ice core dating, which is based on the link between air content of ice and local insolation (Raynaud et al., 2007).
Our study proves that continuous wavelet transform (CWT) is the most suitable tool for tuning the preliminary dated air content records on the calculated local insolation time series. The uncertainties associated with applying this technique to the experimental air content records have been thoroughly investigated. The new dating method was for the first time applied to constructing the orbital time scale for the Dome Fuji ice core, using a composite air content record obtained from this site. A standard error of the thus obtained timescale was evaluated not to exceed ±2.1 ka, that is, close to the standard error of the optimized multi-proxy, multi-site AICC2012 chronology, previously developed for five drilling sites in Antarctica and Greenland.
Keywords: ice core, air content of ice, insolation, ice dating, wavelet transform, paleoclimate.

of different regions of the White sea||30|
There are presented the results of multiyear research (2010, 2012 and 2015 and 2016) of aliphatic hydrocarbons and suspended matter in snow-ice cover of two regions of the White Sea: the Rugozerskaya bay (near the biological station of Moscow state University, the periphery of the Kandalaksha Bay) and the mouth of the Northern Dvina (near Archangelsk). Due to the atmospheric pollution in the heating season, hydrocarbon concentration increases, especially in the mouth of the Northern Dvina (up to 616 mg/l). In the ice, according to the conditions of ice formation, the concentration of the studied substances occurs in different parts of the core. In the top part of the ice the inflow of hydrocarbons with snow influence hydrocarbon concentration and in the bottom part the main role plays the inflow with under-ice water, in particular, a big role goes to the processes on the border ice-water. A comparison of the obtained data with the results of the research of hydrocarbons was produced in snow and ice in the background areas of the Arctic.
Keywords: White Sea, snow, ice, aliphatic hydrocarbons, suspended matter, organic matter.

in the stages of sea ice development in northeast part of the Kara sea
during the autumn and winter period||41|
On a basis of the analysis of archived ice charts for 1997–2016 calculations of changes in the stages of sea ice development composition in northeast part of the Kara Sea during the autumn and winter period are executed. The obtained data allowed establishing with 10 days discretization the changes in quantity (area) and corresponding thicknesses for all stages of sea ice development and the periods of their prevalence from the beginning till the end of ice formation. The essential distinctions between the stages of ice development composition of the drifting and fast ice exhibiting in an earlier appearance and different relative quantity of the first year ice within the fast ice zone are revealed.
Study of sea ice development composition in the northeast part of the Kara Sea during the “cold” and “warm” climatic periods, at the final stage of ice formation revealed their essential distinction.
Such studies were not performed earlier. Its results supplement ice conditions characteristics of northeast part of the Kara Sea and can be used when developing techniques of the ice navigation conditions forecast in winter time.
Keywords: Northeast part of the Kara Sea, stage of ice development, drifting ice, fast ice.

First results of permafrost monitoring on the cryospheric site
of Russian scientific center on Spitsbergen (rscs)||67|
The system of long-term permafrost observations was organised on the cryospheric site of Russian Scientific Center on Spitsbergen in summer 2016. The monitoring site is established in the vicinity of mining settlement Barentsburg on a sequence of Holocene marine terraces. The core drilling showed that the thickness of gravel sands and clays with massive and schlieren cryostructure forming the accumulative terraces is of 2–7 m. Cretaceous and Neocene fractured sandstones and mudstones underlie them. Automated thermistor cables were installed in two boreholes to monitor the temperature on the depth of zero annual amplitude and seasonal distribution of zero-degree isotherm. The temperature –2,37 °C was measured at 15 m depth. The thickness of active layer measured at ten meter net on the observational site of 100100 m varied from 1,15 to 2,60 m with average of 1,56 m. Chemical analysis of aqueous extract revealed a geochemical barrier at 0,8–1,6 m below permafrost upper boundary in the period of maximum thawing, which apparently marks maximum seasonal thaw depth during the Holocene climatic optimum. In this paper recommendations on continuing and extending of pilot permafrost dynamic observations on Spitsbergen are given.
Keywords: permafrost, Spitsbergen, active layer.

The research of the influence of SST anomalies in the low latitudes of the North Atlantic on the sea ice cover and surface air temperature in the marine Arctic was fulfilled. Series of water temperature in the section along the Kola meridian, data of sea surface temperature in the the Atlantic Ocean, series of the average surface air temperature in the marine Arctic, data of extent of sea ice extent in the Arctic Ocean and the North hemisphere were used. Multivariate correlation analysis was used to determine the maximum correlation coefficients between SST anomalies and climate characteristics and corresponding delays (within 33–38 months). The formation scheme of remote SST influence on anomalies in the Arctic Ocean is proposed.
Keywords: Northern Atlantic, Sst anomalies, Arctic, sea ice.

biodiversity within the North pole region||104|
In conditions of modern climate warming, the sea ice cover of the Arctic Ocean has been shrinking, and since the late 90’s there have been a gradual shift of dominance of multiyear ice to seasonal ice. As a result of the rebuild in the qualitative composition of the ice cover, it is necessary to expect possible changes in the composition and structure of biological communities that inhabit the sea ice. The aim of this work is the analysis of the species composition of the sea ice flora and fauna, which based on the result of observations in the North Pole area of the Arctic Ocean for the period 2007–2015. This analysis is held here without discussion of causes of changes under the influence of natural or anthropogenic factors.
Keywords: Central Arctic Basin, sea ice, cryoflora, cryofauna, species composition, species number, similarity, diversity.
