Estimation of sea-ice thickness and volume in the Sea of Okhotsk based on ICESat data.

ABSTRACT: Sea-ice thickness in the Sea of Okhotsk is estimated for 2004-2008 from ICESat derived freeboard under the assumption of hydrostatic balance. Total ice thickness including snow depth (h _tot ) averaged over 2004-2008 is 95 cm. The interannual variability of h _tot is large; from 77.5 cm (2008) to 110.4 cm (2005). The mode of h _tot varies from 50-60 cm (2007 and 2008) to 70-80 cm (2005). Ice thickness derived from ICESat data is validated from a comparison with that observed by Electromagnetic Induction Instrument (EM) aboard the icebreaker Soya near Hokkaido, Japan. Annual maps of h _tot reveal that the spatial distribution of h _tot is similar every year. Ice vol
