| Summary: | about 28 min have trapped the West Sakhalin Current (WSC) during its maximum intensity. The current was observed as a narrow strip the width of about 15 km adjacent to the northwestern Sakhalin coast. Backscatter contrasts in the convergence region between the Tsushima Current and the WSC reached 20 dB. Such contrasts were due to the combined effect of the sea surface temperature difference and wave-current interaction in the convergence and shear zones. The surface manifestations of the several packets of internal waves were clearly visible in the southeastern part of the Tartar Strait and in LaPerouse (Soya) Strait. Transformation of the internal wave packets is noted near the WSC’s boundary. Joint analysis of ERS-2 and Envisat images allowed estimating the movement |
