comment video third meeting oceanography
Oceanography Driven by forces such as wind, tides, and gravity, currents keep our oceans in constant motion. Currents move large amounts of water great distances. Countless currents have been named, but the seven major ones are the West Wind Drift (or the Antarctic Circumpolar Current), East Wind Drift, the North and South Equatorial currents, the Peru Current, the Kuroshio Current and the Gulf Stream. These currents flow in large rotating loops called gyres. In the Northern Hemisphere, gyres spin in a clockwise direction, and in the Southern Hemisphere, gyres spin in a counterclockwise direction. This is because of Earth’s spinning rotation and is called the Coriolis Effect.
