Abstract

Impact of the Amur River discharge and coastal upwelling on the water circulation in the Tartar Strait (the Japan Sea). A.G. ANDREEV (V.I. Il’ichev Pacific Oceanological Institute, FEB RAS, Vladivostok).

The distribution of the low salinity Amur Lyman water in the Tatar Strait (the Japan Sea) was analyzed in September–
October (2002–2017) using satellite data on sea surface height and concentration of suspended organic carbon. The
study of water dynamics using satellite geostrophic velocities and water temperature showed the variability of surface
water circulation, related to the Amur River discharge and coastal upwelling. An increase in the Amur River discharge
(2013, 2016) results in the sea level rise and enhanced anticyclonal (clockwise) water circulation in the northern Tatar
Strait and the Amur Lyman water transport to the south along the mainland. The decrease of the Amur River discharge (2002, 2008) leads to the low sea level and cyclonic water circulation in the northern Tartar Strait. Coastal upwelling leads to the decreased sea level and formation of the cyclonic water circulation in the Tartar Strait.
