Geographical location of the Sea of Okhotsk

Most of the marginal seas in the northwest Pacific Ocean are surrounded by different terrain areas in Northeast Asia. The Sea of Okhotsk is connected to the Siberian coast of Russia in the west, from the estuary of Heilongjiang in the south to the estuary of Pengri in the north. It borders kamchatka peninsula and Thousand Islands in the east, Hokkaido in the south and Sakhalin Island in the southwest. The sea of Okhotsk covers an area of 654.38+0.583 square kilometers with an average water depth of 777 meters. Sea water washes the coasts of Japan and Russia.

Most continental coasts are high and steep rocky coasts, among which are scattered estuaries of regional rivers. Such as Heilongjiang, Udi, Ohota, Jiriga and Pingrenna rivers. The seabed slopes from north to south and southwest. The north and northwest are continental shelves with a depth of 200m, and the rest (about 70% of the total area) are continental slopes with a depth of 200-1500m.
