The model reproducibility is first examined in detail. Comparison with surface drifter, mooring, and HF ocean radar data shows that the model successfully reproduces the realistic flow fields, which include the vertical structure and seasonal variation of the East Sakhalin Current and Soya Warm Current. Thus the particle tracking experiments in these regions are considered to provide reliable results. The results of particle tracking experiments on the drift/diffusion of water from Amur River and northwestern shelf will be shown during the presentation. Also, the formation mechanism of the cold water belt off the Soya Warm Current will be discussed.
Direct observations of sea-ice thickness and brine rejection off Sakhalin in the Sea of Okhotsk-(��Į ��) ȯɽ�� :
From December to June 2002-03, sea-ice and oceanic data were obtained from moorings near Sakhalin in west central Okhotsk Sea. Ice draft measured by sonar reveals distinct periods of thin and thick ice. Thin-ice periods in January-March corresponded to offshore ice movement and increasing seawater salinity. Dense shelf water was observed suggesting that this region is another possible source. The measured salinity corresponds well with that derived from via heat-flux calculations. Brine rejection from ice growing in the coastal polynya is responsible for much of the observed salinity increase. The periods of thick-ice incursion are likely indicative of heavily deformed pack formed further north and drifting south with the current. The mean draft (1.95 m) and keel frequency are close to values observed in the lower Arctic. Freshwater transport estimated from the observed ice thickness and velocity is larger than that of the Amur river discharge.
