	The results of methane concentration observations in the atmospheric surface layer, carried out in expeditions of the Arctic and Antarctic Research Institute in 2002–2014 years are summarized. The observations were executed at the drifting stations “North Pole-36” and “North Pole-39” in the Central Arctic, at Hydrometeorological Observatory Tiksi, located on the shore of the Laptev Sea in the permafrost zone, and on the research station “Island Samoilovsky” in the delta of the Lena River. Keywords: methane, atmospheric surface layer, drifting station, the Arctic Ocean.

	Possible variants of arrangement of system of hydroacoustic monitoring of dangerous ice formations on boundaries of “emergency disconnection zone” of offshore oil and gas platform from the underwater equipment are considered. For maintenance of platform protection from ice threats the system which is based on high-frequency multi beam sonars (multi beam echo sounders, ice profilers) for sounding of ocean surface which are used to create stationary or mobile “acoustic frontiers” is offered. The configuration of means providing operability of system of hydroacoustic monitoring, for various variants of arrangement of “acoustic frontiers” is given. Features of underwater acoustic channel typical for freezing sea water areas are considered. Keywords: ice threats, monitoring, underwater acoustic, oil and gas platform.
	V.E. Borodachev, I.V. Borodachev.  Kara sea ice extent and the Arctic climate variations	57
	This article provides an analysis of the long-term fluctuations of the Kara Sea ice extent associated with the Arctic climate variations. It has been shown that its secular ice extent downgrade is determined by the global warming, which trend magnitude +0,01355 grad/year. A paradoxical phenomenon is found out — a natural decrease in ice extent in the north-eastern part of the sea up to the second 10-days period of July with further abrupt change to increase in ice extent with remaining background global warming of the Arctic. A large-scale cycle, typical of both parts of the Kara Sea, is revealed in the long-term fluctuations of the ice extent, the formation of the cycle is due to cyclical changes in the Arctic climate. It is shown that the processes of cooling and warming of the Arctic have defined sharply delineated periods of accumulation and reduction the summer ice area in the Kara Sea. There is no doubt that the processes of interaction between the ice covering such a small area of the Kara Sea and climate in the Arctic are planetary. Keywords: sea ice, ice extent, climate, Kara Sea.

	The basic principles of treatment and correction of long-term hourly sea level records are stated. The basis of a new method is made by calibration of a quasitidal component of the tidal signal on the basis of tidal model in concrete point. Efficiency of a method at an assessment of quality of materials of long-term sea level records and reduction of time series in databases to uniform massifs is noted. By means of a new method steady estimates of the harmonic constants of the constituents on a number of points with doubtful initial materials of sea level records are received. Keywords: tides, tidal analysis, calibration of the tidal signal, sea level dataset.

	The general regularities of temperature and salinity distribution are given to the winter and summer periods on the shelf of the Laptev Sea, average for historical period 1950-1993. According to the Russian-German expedition of “LAPEX-2013/TRANSDRIFT-XXI” the termohaline condition of the Laptev Sea in the summer of 2013 differed from climatic as in a surface layer, and bottom layer. On the shelf more deeply than 40 m cold water with a temperature from –1,51 °C to –1.76 °C and salinity from 33,92 to 34,44 remained. Thickness of a cold layer over a of the shelf brow was in range 28–53 m. Configurations of volume of cold shelf water on the shelf and behind a shelf brow on the meridional hydrological sections constructed according to unique mesoscale U-STD observation indicate bifurcation of a layer of cold shelf water behind a shelf brow. The top part of a layer continued to extend to the north on the horizons of 40–50 m to the Arctic basin, and the second part of a layer slipped on a shelf slope in deep-water part of the basin. The facts established according to historical data and researches of the Russian-German expedition of “LAPEKS-2013/TRANSDRIFT-XXI” allow to make a dicision that cold shelf waters of the Laptev Sea as fill up cold lower halocline of a deep ocean, and formations of a bottom layer of maginal slope are a source. Keywords: the Laptev Sea, cold shelf waters, bifurcation of a layer of cold shelf waters behind a shelf brow, cold shelf waters as a source of supplying a cold halocline and bottom water of maginal slope.

	In last decades, the climate of our planet is undergoing major changes. The most notable climatic changes observed in the Arctic region, which are called “Arctic amplification.” This is a decrease in the area of multi-years ice in 2007 and 2012, the temperature rises of intermediate Atlantic waters, increasing surface temperature. In this paper, an analysis of long-period variability of temperature transformed Atlantic waters (TAW) in the fjords of the West-Spitsbergen island (Isfjorden, Grønfjorden, Hornsund, Kongsfjorden and Bellsund) in the first period (1920–1940) and modern (1990–2010) warming in the Arctic. It is shown that the data corresponds to the periods of rise in temperature in the layer of the TAW and surface air temperature (SAT) for the area of the Svalbard. Keywords: Arctic, Spitsbergen, climate variability, Atlantic waters.
