2. IPY has showed the feasibility of addressing key polar issues The International Polar Year was very important for the Russian polar research. During the period of IPY 2007/08 Russian polar researchers have got approximately 27 million USD in addition to the basic financial support. These funds were spent primarily on the field works and the development of observational infrastructure in the Russian Arctic. Number of Russian IPY 2007/08 expeditions Marine Land Arctic Antarctic

15. Transpolar Drift System of the Arctic Ocean. “Laptev Sea” Cluster (H. Kassens, L.A. Timokhov) German partners: GEOMAR, AWI, Mainz Academy, Universities of Trier and Kiel Russian partners: AARI, GOIN, SPbSU, MSU, Shirshov Institute, Lena-Delta Reserve Main Goals: - Changesofthe Transpolar Drift System as a resultofclimatechange; • - Ecologicalconsequencesofclimatechange in theregion; • Regional changesoftheatmosphere/sea/ice/ocean • system; • StabilityoftheArcticclimatesystem: historyofthe Transpolar Drift. • Target 1. Monitoring of sea ice transport and fresh water content in sea ice. Study fresh water transport by surface and subsurface currents between seas and to the Arctic Basin. • Target 2. To estimate fluxes of fresh water and materials to/from the Arctic Basin and the rates of internal transformations within the Arctic Ocean. • Target 3. To explore the role of fresh water transport in a variability of Transpolar System. • Target 4.To investigate the processes on the Arctic continental shelves that influence on the global cycling of carbon, nitrogen and phosphorous and their intensity.

Last cruise was in September 2015 • Totally more than 1100 oceanographic • stations in the Laptev Sea • 3 books and more than 500 articles published • About 300 presentations at the conferences

17. NABOS: Nansen Amundsen Basins Observational System MAIN GOALS OF NABOS: (a) To quantify the water mass structure and its variability (b) To evaluate the mechanisms by which the Atlantic Water is transformed on its pathway along the slope (c) To estimate the impact of the Atlantic Water heat transport on ice and climate (d) To estimate the rate of exchange between the arctic shelves and the interior in order to clarify mechanisms of the arctic halocline formation First phase of NABOS ARCTIC AND ANTARCTIC RESEARCH INSTITUTE INTERNATIONAL ARCTIC RESEARCH CENTER UNIVERSITY OF ALASKA FAIRBANKS
