current. In the sense of a large body of water moving in a certain direction, current derives from a Latin word meaning “running.” There are some 30 major currents. The world’s great- est current is the West Wind Drift Current, which flows at one point at the rate of 95 billion cubic feet per second and ranges from 185 to 1,240 miles. The strongest current is in British Co- lumbia’s Nokwakto Rapids, which travel up to 18.4 mph. An unlikely story says Aristotle drowned himself because he could not explain the current off the island of Euboea in the Aegean. Scientists are still mystified by the current and can’t explain why it reverses its direction some 14 times a day. See gulf stream. |
