Drake Passage

The Antarctic Circumpolar Current flows through the Drake Passage. This current is the most voluminous in the world, with an estimated flow rate between 95 and 150 million cubic meters per second. The Drake Passage, a waterway connecting the Atlantic and Pacific oceans, accelerates the velocity of this current due to the constriction of the passage.1
