Northwest Pacific Basin

The Oyashio Current (from the Japanese for “mother stream”) brings cold water south from the Bering Sea, along the western edge of the Northwest Pacific Basin, forming the western arm of the subarctic gyre. Where the Oyashio Current meets the warm waters of the Kuroshio Current (“black stream”) off Japan, there is a productive fishery.
