Estimation of the volume of sea ice cover in the Sea of Okhotsk and related atmospheric conditions for 1991/92-1998/99 winters
The volume of sea ice cover in the Sea of Okhotsk during 1991/92-1998/99 winters (December-April) was estimated by using SSM/I data sets with the S/KIT algorithm (Tateyama et al., Bull. Glaciol. Res., 17,23,2000) which can distinguish among fast ice, floes, young ice, new ice and multi-year ice type...
