Abstract

The biogeographic characteristics and interannual variation of diatom and silicoflagellate floral fluxes are outlined in the western North Pacific, the Bering Sea, and the Arctic Ocean, based on the time-series sediment trap studies at Stations NAP10t, AB, SA, 50N, K2, KNOT, 40N, and S1. In this paper, two paleoceanographic studies are also introduced. In the paleoceanographic study in the Bering Sea for last 4 million years, long term cooling trend were inferred from the assemblage secession of major diatoms and silicoflagellates. As the another paleoceanography topic, it was estimated by silicoflagellate fossils that the sea surface condition in the middle Eocene Arctic Ocean (ca.45－50Ma) were relatively warm and isolated from other oceans such as the North Atlantic.
