Several current meters were deployed in 1996–1998 in the vicinity of La Perouse (Soya) Strait aiming to provide in situ observations of the Tsushima and West Sakhalin currents. Simultaneous moorings at two stations, Tetany 106 and Tetany 202+, clearly demonstrated convergence of these currents in the summer period on the southwestern shelf of Sakhalin Island. For both moorings more than 70 % of the total energy was related to diurnal tides. Non-tidal currents were mainly barotropic and had significant seasonal and fortnightly components. The West Sakhalin current was found to play a key role in water exchange between the Sea of Okhotsk and the Sea of Japan.
