Material Detail

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 map illustrates the network of currents known as the great ocean conveyor belt, or the thermohaline conveyor, and shows which portions are travelled by warm and shallow, or cold and salty, currents. A background essay and discussion questions are included.
