Research Abstract

The present research program focuses on the biological processes in the seasonal ice-covered sea areas in the northern hemisphere, namely (1) St Lawrence Island polynya in Bering Sea, (2) Saroma-Ko lagoon in Hokkaido, Japan, (3) Resolute Passage in the Canadian arctic, and (4) Spitzbergen area. The program is quite multi- disciplinary and covers the following fields ; (i)physical processes of oceanography, sea ice and meteorology, (ii)ice algae primary production and phytoplankton production and their biological, physical and chemical processes, (iii)secondary production and its tropho-dynamic links in the ecosystem, (iv)biochemical adaptability of ice algae, and (v)geochemical cycling processes.
The joint field works among Japanese, US, Canadian and Norwegian scientists in the above four areas were very successful and the scientific results will be published in the "Journal of Marine Systems" as a special volume.
