| The Sea of Japan is a marginal sea within the Pacific Ocean, separated from it by the Japanese Islands. It is separated from the Sea of Okhotsk by the island of Sakhalin, and from the Yellow Sea by the Korean Peninsula. Area - 1,062,000 km². The greatest depth is 3742 m. In the south, a branch of the warm Kuroshio current enters. Surface currents form a gyre, which consists of the warm Tsushima current in the east and the cold Primorsky current in the west. In winter, the surface water temperature is from -1-0 ° C in the north and northwest, in the south and southeast it rises to +10 - +14 ° C. In summer, the surface water temperature rises from 18-20 ° C in the north and up to 25-27 ° C in the south. |

| The vertical distribution of temperature is not the same in different seasons in different areas of the sea. In summer, in the northern regions of the sea, the temperature of 18-10 ° C is kept in the 10-15 m layer, then it drops to + 4 ° C at the 50 m horizon and, starting from a depth of 250 m, the temperature remains constant at about +1 ° C. In the central and southern parts of the sea, the water temperature decreases rather smoothly with depth and reaches + 6 ° C at the 200 m horizon, starting from a depth of 250 m the temperature is about 0 ° C. According to ice conditions, the Sea of Japan can be divided into three regions: the Tatar Strait, the area along the coast of Primorye from Cape Povorotny to Cape Belkin and Peter the Great Bay. In winter, ice is constantly observed only in the Tatar Strait and Peter the Great Gulf, and in the rest of the water area, with the exception of closed bays and bays in the northwestern part of the sea, it does not always form. According to long-term data, the duration of ice in Peter the Great Bay is 120 days. In the southern part of the Tatar Strait ice is 40-80 days, in the northern - 140-170 days. The salinity of the Sea of Japan is 33,7—34,3 ‰. |
