The oceans are in constant flux. The movement of ocean water is readily observable in the rise and fall of the tides and the continual lapping of waves along the coastlines of continents and islands. Less obvious is the network of currents that constantly circulates ocean water from one side of the globe to another. This image from GRID-Arendal illustrates the path of the great ocean conveyor belt, also known as the thermohaline conveyor.
