By: Henry and Jawad Per.2 April 24, 2008 Global Circulation By: Henry and Jawad Per.2 April 24, 2008

What is global circulation? Ocean water that circulates or travels through all of Earth’s ocean basins Global circulation consists of surface currents and deep water currents

What does global circulation do? Transports material throughout Earth’s oceans such as oxygen and nutrients Transports heat throughout Earth’s oceans

Global Circulation Images

Deep and Surface Currents Deep currents are movements of ocean water far below the surface. Surface currents are horizontal stream like of movements of water that occur at or near the surface of the ocean.
