Observation of anomalous spectral downshifting of waves in the Okhotsk Sea Marginal Ice Zone.

Waves in the Marginal Ice Zone in the Okhotsk Sea are less studied compared to the Antarctic and Arctic. In February 2020, wave observations were conducted for the first time in the Okhotsk Sea, during the observational program by Patrol Vessel Soya. A wave buoy was deployed on the ice, and wave observations were made by a ship-borne stereo imaging system and Inertial Measurement Unit.

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

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 ( ) averaged over 2004-2008 is 95 cm. The interannual variability of is large; from 77.
