On July 2, the vessel of the National Scientific Center for Marine Biology of the Far Eastern Branch of the Russian Academy of Sciences “Akademik M.A. Lavrentiev” has left. Its tasks include the study of the ecosystems of the guyot and seamounts of the Imperial Ridge. On July 3, an expedition began to study the ecosystems of the Kara Sea on the research vessel of the Institute of Oceanology, “Akademik Mstislav Keldysh”. On July 10, for the second time this year, departed the research vessel “Professor Vodyanitsky” of the Institute of Biology of the Southern Seas named after Kovalevsky of Russian Academy of Science.
4 VNIRO specialists participate in the 76th cruise of research vessel “Akademik Mstislav Keldysh” in the Kara Sea:
Svetlana Frenkel - Senior Researcher, Far East Marine Fishes Department, VNIRO;
Olga Vorobieva - Specialist of the Fisheries Ecology Department of VNIRO;
Roman Melnik and Yuri Goncharov are researchers at the coastal research laboratory of the Northern Division of the Polar Division of VNIRO (PINRO).
In the second decade of July, complex works were carried out in the Kara Sea in two sections: in St. Anna's trench, including the outer shelf area and the continental slope; and on the meridian section from the northern tip of Novaya Zemlya to the desalinated part of the Ob estuary, including the landfill in the Ob Bay.
The special attention of the scientific group of VNIRO was paid to the study of the daily dynamics of distribution and feeding of zooplankton in St. Anna’s Trench and at the northern tip of Novaya Zemlya.
To determine the production characteristics of the Kara Sea, samples were taken for chlorophyll concentration “a” with its separation into fractions of micro- and nannoplankton, and values of the primary production of micro- and nannoplankton in the surface horizon and in the layer of chlorophyll maximum were calculated.
Experiments on the study of the physiological state of mass species of plant-eating forms of zooplankton have been started.
For the first time in the waters of the Kara Sea on the central shelf, mass catches of larvae and fry of the Arctic cod were obtained (up to 1,730 specimens per Bongo catch). At the stations in the area of the Ob beach, isolated specimens of navaga larvae were found.
