Abstract
In the Sea of Okhotsk, ice formation begins at it's northwestern corner ; near the Shantalski islands in the latter of October. The ice area rapidly extends Southeastwards along the East coast of Sakhalin facilitated by NW'ly winds and low saline water. In this paper, I attempted to catch the daily ice limits of the Sea of Okhotsk using the meteorological satellite and radio sonde data at 17 stations for two years. 5 day-mean surface water temperature, 10 day-mean 850mb temperature and monthly-mean 500mb temperature were also observed.
