Kuroshio Current

From Wikipedia, the free encyclopedia

The Kuroshio Current (Japanese 黒潮) is the world's second-largest ocean current, after the Antarctic Circumpolar Current. It begins in the western Pacific Ocean off the east coast of Taiwan and flows northeastward past Japan, where it merges with the easterly drift of the North Pacific Current. It is analogous to the Gulf Stream in the Atlantic Ocean, transporting warm, tropical water northward towards the polar region. It's also sometimes known as the Black Stream—the English translation of kuroshio, and an allusion to the deep blue of its water—and also as the Japan Current.

Its counterparts are the North Pacific Current to the north, the California Current to the east, and the North Equatorial Current to the south.

There is a high concentration of uranium passing through the current every year (about 5.2 million tons)^[1].

The warm waters of the Kuroshio Current sustain the coral reefs of Japan, the northernmost coral reefs in the world. The branch into the Sea of Japan is called Tsushima Current.

It boosts the fishing industry in Japan.^{[citation needed]}
