Abstract
We review the paleoceanographic studies in the Sea of Okhotsk based on sedimentary records, mainly focusing on the following four topics: seawater temperature, sea ice, intermediate water formation, and productivity. The reconstructed environment of the glacial Sea of Okhotsk was significantly different from the modern one. Our attempts for scientific drilling in the Sea of Okhotsk ODP/IODP proposal 477 to obtain long-term sedimentary archives are also presented.
