Oil modeling system for ice-infested seas | 7 | | 12.08.2007 V.V.STANOVOY, I.V.LAVRENOV, I.A.NEELOV OIL SPILL MODELING SYSTEM FOR ICE-INFESTED SEAS The modeling system of accident oil spills in the ice-infested arctic seas is developed. This system consists of dynamic-thermodynamic model, wind waves model and oil spill transport and transformation model. The brief description of models and results of numerical experiments are presented. The conclusion is made, that the developed modeling system is capable to adequately describe the behaviour of accident oil spills on the ice-free sea surface and under drifting ice conditions. The system, if necessary, can be used as a basis of regional operative model.

Features of land fast ice forming at freezing seas coastal zone | 17 | | 12.11.2007 P.V.BOGORODSKY, A.V.MARCHENKO, A.V.PNYUSHKOV FEATURES OF LAND FAST-ICE FORMING AT FREEZING SEAS COASTAL ZONE The land fast ice forming at freezing seas coastal zone is considered with the use of thermodynamic model taking into account energy exchange in atmospheric boundary layer. On the example of Baydaratskaya Bay of the Kara Sea the quantitative estimates for fast ice growth under changing meteorological situations are elaborated. The conditions of ice moving up to the coast under wind effect have been studied. It was shown that during ice forming period the under ice water layer salinity can exceed for an order its initial value.

Role of sea ice in formation of an annual cycle of carbon dioxide in high-latitude marine Arctic | 28 | | 22.11.2007 G.V.ALEKSEEV, A.P.NAGURNY, A.P.MAKSHTAS, N.E.IVANOV, S.V.SHUTILIN ROLE OF SEA ICE IN FORMATION OF AN ANNUAL CYCLE OF CARBON DIOXIDE IN HIGH-LATITUDE MARINE ARCTIC Features of variability of СО2 concentration in an atmosphere over high-latitude Arctic Ocean and a role of sea ice in their formation are investigated. It is used the global data and results of observations during IPY 2007 research. Methods include the statistical analysis of global data of СО2 contents in the atmosphere, direct measurements of its concentration over ice cover of Arctic Ocean and the analysis of chemical reactions within the sea ice. It is shown that polar amplification of annual cycle of СО2 concentration over the Arctic Ocean is connected with active influence of sea ice on formation of a seasonal cycle CO2. Formation, increase of thickness and structure change of ice during a winter season is accompanied by allocation СО2 into subice layer of water and directly to the atmosphere. Measurements of СО2 concentration in surface layer of the atmosphere among ice along the sections from Barents and Kara seas to the North Pole have confirmed the growth of concentration in the poleward direction. It was the first to specify the active role of sea ice in the formation of a seasonal cycle of СО2 content and to speculate that the Arctic Basin is more likely a source than a drain of СО2 in the average for year. The measurements will be continued in 2008 with using of the modern devices for measurement of СО2 fluxes through the ice.

Laboratory and natural investigations of mechanism of «ice-cushion» formation near the icebreaker's board | 37 | | 23.04.2007 K.P.TYSHKO, N.V.CHEREPANOV LABORATORY AND NATURAL INVESTIGATIONS OF MECHANISM OF «ICE-CUSHION» FORMATION NEAR THE ICEBREAKER'S BOARD The results of natural investigation of «ice-cushion» composition near the icebreaker's board showed that mechanism of the development of this phenomenon (in other way ice sticking) is closely linked with dynamic conditions of ice formation that provide appearing under ice cover a thick layer of frazil ice. Laboratory modeling of ice sticking was conducted with accounting two basic things: frazil ice can form both at the presence of water supercooling and the heat outflow from open water during winter. In the result of investigations on both directions two models of this phenomenon were proposed. In one of them the contact between ice crystals and the board of icebreaker appears when its entering in the zone of such ice causes the fast realization of the energy of supercooled surface water layer (thermodynamic model). In the second model this contact is provided by hydraulic forces acting in process of taking sea water on board through special tanks (ice boxes). In icebreaker's hull they have small holes or notches near those the first contact layer of «ice-cushion» forms (hydraulic model). Both models support the idea about basic role of frazil ice in the mechanism of ice sticking.

Potential usefulness of hydrometeorological forecasts and real data joint statistics in practice | 43 | | 18.11.2007 V.G.DMITRIEV, N.V.RYBCHAK POTENTIAL USEFULNESS OF HYDROMETEOROLOGICAL FORECASTS AND REAL DATA JOINT STATISTICS IN PRACTICE By modern point of view on the weather forecast using it is clear that forecast uncertainty should be concerned. Decision makers are need in estimations of distances between forecasts and real data and probabilistic forms of forecasting are preferred. This paper is concerned with way to estimate an accuracy of the individual categorical forecasts within distribution-oriented conception. It was shown that categorical forecast uncertainty could be estimated as a measure of distances between distribution functions. As a measure of distances a norm in adequate function space could be taken. Exact formulas for distribution functions and a measure of distances in interest are shown. All conclusions are based on the real daily forecast and fact data for Murmansk region (2005–2006).

Results of the studies of aerosol characteristics in 52nd RAE | 67 | | 13.11.2007 S.М.SAKERIN, D.М.КАBАNОV, V.S.КОZLОV, М.V.PANCHЕNКО, V.V.POLKIN, А.B.ТIKHОМIRОV, N.I.VLASOV, V.F.RАDIОNОV, А.V.SМIRNОV, B.N.HОLBЕN, I.А.SLUTSKER, L.P.GОLОBОКОVА RESULTS OF THE STUDIES OF AEROSOL CHARACTERISTICS IN 52nd RAE We consider the results of the studies in 52nd Russian Antarctic Expedition; the studied atmospheric aerosol characteristics were: the number concentration and ion composition of soluble aerosol fraction, mass content of aerosol and microcrystalline carbon («soot») in the near-water atmospheric layer, as well as aerosol optical depth (AOD) and total moisture content of the atmosphere. The statistical data of aerosol characteristics for four studied regions are presented. The maximum values for all characteristics were recorded in the region of north trade wind, and the smallest values near the Antarctic coast. The mean characteristics near Russian Antarctic stations were: 0,029 (0,5 m) for atmospheric AOD; 0,39 g/cm2 for moisture content; 2,1 g·m-3 for aerosol mass content; and 0,01 g·m-3 for «soot» mass concentration. We note that the spatial distributions of AOD and aerosol and «soot» mass concentration in the southern hemisphere show the latitudinal dependence, i.e., the decrease of the values from equator toward Antarctic coast. For two regions (South Ocean and Antarctics) we compare the atmospheric AOD, measured in the 52nd RAE, with the data of other studies and indicate good agreement of the results. The statistical characteristics of the chemical composition of the near-water aerosol in the atmosphere of South Atlantic are presented. The mean concentrations of ions of soluble aerosol fraction were: 3,03 for Na+; 6,03 for Cl-; 0,183 for K+; 0,212 for Mg2+; 0,31 for Ca2+;1,77 for SO42-; 0,357 for NO3-; 0,817 for NH4+;2,183 g·m-3 for Br-.

Measurement results indicate that for the period from 2003 to 2005 inter-annual СО2 concentration growth in South hemisphere do not significantly changed from year to year and corresponds to the mean growth rate for the last decade, which is equal to 1,9 ppm per year. In the north latitudes (20–50°N) inter-annual СО2 concentration growth in autumn-winter season have changed from 1 ppm for the period from 2003 to 2004 to 5 ppm for the period from 2004 to 2005. Methane concentration above the ocean surface and at Bellinsgauzen stations was unchanged in the period from 2003 to 2006. The mean growth rate of СО2 concentration for South hemisphere was determined as 1,59 ppm per year for the period from 1987 to 2006 on the base of the data of Soviet Antarctic Expedition (SAE) in 1987 and Russian Antarctic Expeditions (RAE) in 2000–2006.

The most attention is payed to the links of active frazil ice formation and intensive outflow of the fresh water formed in under bottom part of continental ice that has a complicated relief.
| | S.D.Stepanjants. Conception of the bipolar distribution of the organisms: origin and modern views, on the Medusozoa example | 89 | | 23.04.2007 S.D.STEPANJANTS CONCEPTION OF THE BIPOLAR DISTRIBUTION OF THE ORGANISMS: ORIGIN AND MODERN VIEWS, ON THE MEDUSOZOA EXAMPLE L.Bergh summarized different interpretations and meanings concerning BIPOLARITY concepts, and, as result, he expanded the next classical interpretation of bipolarity: «Bipolarity is an interrupted distribution of identical or closely related species (or higher taxa level) of flora or fauna in polar, temperate or subtropical zones of both hemispheres, characterized by their absence in tropics». Proceeding from the Ch.Darwins' statement that some plants species typical for the temperate zones of the plains of Europe, southern Australia and New Zealand, are known in high-mountains areas of tropics, Bergh concluded that it should be possible to characterize the presence and distribution of temperate forms in the deep cold water of the tropical and subtropical zones as bipolar species. Analysis of distribution peculiarities of several Medusozoa (Cnidaria) taxa allows us, following Bergh, to offer some other interpretation of bipolarity phenomenon. Bipolarity is wide distribution of either the same, or closely related, or even unrelated taxa at the species and higher levels of flora and fauna having similar morphological characters and inhabiting similar environments of the cold zones or cold waters of both hemispheres. At present 23 species, 32 genera and 5 families of Medusozoa could be named as bipolar.

Seasonal evolution of zooplankton amount in Ardli Bay (King George Isl., South Shetland Islands) | 97 | | 14.06.2007 N.V.USOV SEASONAL EVOLUTION OF ZOOPLANKTON AMOUNT IN ARDLI BAY (KING GEORGE ISL., SOUTH SHETLAND ISLANDS) Zooplankton sampling was carried out during the year from 20 February 2006 to 6 February 2007 in Ardley Cove (King-George Island, South Shetland Islands) at two different distances from the shore. It was found that species number rises but total abundance declines with distance from shore. No pattern was found in vertical distribution of zooplankton. Two major peaks of zooplankton numbers were traced during the year: in March and June-July with one less prominent in the beginning of May in water layers below 10 m depth. Season dynamics of the most abundant species was discovered to be similar to that in the much deeper Admiralty Bay, located on the same Island.
