Preliminary results of expedition «AARI Ice Camp»

• During the period of ice camp drift in the Arctic Ocean significant amount of oceanographic, sea ice, meteorological and other observations was carried out. In a total 76 oceanographic soundings were done. 47 hydro chemical samplings at various depths were taken with subsequent chemical analysis. Long series of ocean currents observations were gained at various depths using 2 acoustic Doppler profilers.

• Infrastructure of the closed «AARI Ice Camp» and its staff were used to organize the camp of the drifting research station «North Pole - 35»

phosphate – 1346silicate – 1346oxygen – 1256pH – 356alkalinity – 347summary phosphorus – 262summary nitrogen – 262nitrates – 262nitrites – 262ammonium nitrogen – 262derived organic nitrogen and phosphorus – 262

Preliminary results of oceanographic studies

• Along with continuing process of Atlantic water layer warming, the process of increase of its thickness and upper boundary position is observed in the Arctic Ocean;• Anomalous increase of water temperature within the layer from 2200-2500 up the bottom possibly due to geothermal causes, is observed within the bottom layer of deep Arctic Ocean regions (Amundsen Basin);• Increase in Atlantic water layer temperature pays significant effect on hydrological and ice conditions in the boundary seas (Kara Sea) where these waters penetrate along the trenches crossing the land slope; • Temperature of waters penetrated to Kara Sea along the St.Anna and Voronin trenches increased by 0.5 degree Celsium in 2007

Studies of sea ice and snow cover

Morphological observations – 5 ice stations• 210 measurement of ice and snow thickness;• 5 ice samplings with subsequent measurements of temperature and salinity profile.Specialized ice observations:• Continuous observations of sea ice parameters and ship movement properties with simultaneous TV-recording from the bridge;• 8897 measurements of sea ice thickness using en-route TV imagery. Studies of sea ice thermal physics and radiative properties:•43 series of measurements of sea ice integral albedo;•16 measurements of snow cover temperature, density and texture profiles ;•2 series of snow cover thermal conductivity;•36 temperature profile measurements in melt ponds;•122 ice thickness profile measurements on the surface of melt ponds, snow cover depth and albedo;• 5 sea ice samplings taken from the surface of melt ponds were described.

2. 3 vertical temperature and salinity profiles in melt ponds were measured at 3 stations on September 8th, 12th and 21th, 3 time series of temperature and salinity in melt ponds were measured at 3 stations on September 6th, 9th and 20th.

3. Morphological structure of melt pond was investigated at the station on September 8th, 2007.

4. During 3 stations measurements of spectral albedo for 12 melt ponds with different degree of snow coverage and general state of ice and snow cover were carried out; 10 cycles of measurements of penetration for incoming visible radiation and estimation of spectral albedo were carried out.

Investigation of sea ice thermal physics and radiative properties

1. 2 sea ice samplings taken from the melt pond on September 6th and 2 samplings taken from the sea ice without melt ponds on September 12th,2007 were analysed

Sample recording of dynamic vessel roll during her movement within the ice

Preliminary results of ornithological observations

Within the expeditionary scientific program ornithological survey of the Franz-Josef Land and Severnaya Zemlya archipelagos was carried out, including the regions of white gull habitat. 8 colonies were observed including 6 new. Unique data on species productivity in seasonal cycle were gained. Significant regional variability of productivity was traced. For the first time satellite sensors were installed on 8 birds in order to trace their migrations.

New quantitative data on distribution of birds and mammals within the region of northern parts of Barents and Kara Seas and adjacent areas of Arctic Basin were gained including new information on ortithological fauna of the mentioned archipelagos.

Organization of the North Pole – 35 drifting station camp

• "NP-35" deployed on ice floe situated NE of Severnaya Zemlya archipelago at 81,3N and 103,5E Deployment was carried out from board R/V Akademik Fedorov with support of MSC atomic icebreaker “Rossiya”. In a total 343.9 tonnes of cargo were deployed on ice.

• NP-35 staff include 21 men including 7 persons from “AARI Ice Camp. The head of NP-35 is a very experienced oceanographer Alexey Visnevsky. The staff includes specialists in oceanography, meteorology, geophysics, aerology, hydrochemistry, hydrography and technical personnel.

• Broad scope of activities is planned for NP-35 with a help of additional oceanographic and geophysical equipment. In addition to standard meteorological observations, aerological set for twice daily sounding of atmosphere is installed.

• Instrumental studies of gazes exchange (methane, carbon dioxide) at the boundary of ocean – ice – atmosphere will be convened.

• Observations on ozone summary concentrations and its vertical profiles in the atmosphere surface layer with a help of balloon will be carried out. These observations will be supported by the only foreign participant at the station – Jurgen Grazer (AWI - Potsdam)
