| Research Abstract |
"North Water Pokynya(NOW) Study" is one of three polynya studies of the "International Arctic Polynya Program, which was planned by the Arctic Ocean Sciences Board. The NOW study was the international collaborative research and Canada was the leading nation. Japan and USA were important countries to share a joint operation of icebreaker together with Canada. In addition, UK, Germany, Denmark, Belgium and Poland participated in the NOW study. In 1997-1999, the NOW study was carried our in and around the North Water polynya on board the Canadian Coast Guard Icebreakers. A total of 17 Japanese scientists were on board six cruises in polynya areas during three years. At the same time, two Japanese worked on the sea ice field adjacent to the polynya. A great wide range of research was carried out such as circulation and heat flux measurement on ice, continuous measurement of surface water chlorophyll along cruise tracks, long-term mooring experiment of sediment traps, plankotn samplings, cultivation experiments of plankton on board, and so on. Results of these measurements and observations have been presented at many meetings and symposia in and outside Japan and scientific papers are prepared to be published in a special volume of international scientific journal. In the Barents Sea, a comparative study of sediment trap experiment was also carried out on board the Norwegian research ship. To clarify a relationship between marine and terrestiral ecosystems, a land-based observation was carried our around Ny-Alesund, Spitzbergen. An open top chamber was installed at the margind of glacial tongue for monitoring observation. At the same time, foraging behavior of sea birds and their food items were observed around bird rookery.
