Short summary
Diatom assemblages in seasonally sea-ice-covered areas of the Sea of Okhotsk, a marginal sea of the western North Pacific, were investigated. We have selected diatom taxa relating to sea-ice coverage by comparing diatom assemblages in sea-ice, sinking-particle, and surface-sediment samples. The results of the study provide fundamental information for the reconstruction of past sea-ice cover based on ice-algal diatoms in sediments in the Sea of Okhotsk and the North Pacific.
