Sea of Okhotsk

The water in the Sea of Okhotsk is supplied by several distinct sources:

  • Continental drainage: Large rivers, including the Amur, Tugur, Uda, Okhota, Gizhiga, and Penzhina, flow into the sea from the continental coast.1
  • Precipitation: Atmospheric moisture contributes to the sea's water balance.1
  • Pacific Ocean: Waters flow into the sea through the straits of the Kuril Islands.1
  • Sea of Japan: Water enters the sea from the Sea of Japan (East Sea) through the La Perouse (Sōya) Strait.1
