Study on the paleoceanography in high latitude of the North Pacific and the Arctic area

Science Summary (common)

[purpose] The aim of this study is understanding of glacial and inter-glacial climate changes and abrupt changes in the Okhotsk， Japan， and Bering Seas and the Arctic area by using the sediment cores. [outline] The cruise is divided in two legs of which research area are the Okhotsk and Japan Seas area (leg. 1) and the Arctic area (leg. 2). The main observation items are site survey (Sea beam and sub-bottom profiler system)， sediment coring (Piston corer， Gravity corer， and Multiple corer)， conductivity， temperature， and depth observation and water collection in the water column (CTD/Rosette sampler)， and plankton collection in the surface water (Norpac net).
