LESSON SUMMARY This lesson helps students explore the role of the Ocean circulation is such an important process in the Earth system because currents transport heat, oxygen, nutrients, and living organisms. Purple arrows indicate cold, deep ocean currents. Cold water sinks near the North and South Poles. Warm surface and cold subsurface flow in the Atlantic Ocean between North and South America, Africa, Europe and Greenland. Warm-core eddies trap and transport a variety of different kinds of animals within them. But there are also significant deep When they approach the eastern-ocean boundaries of continents, they turn and flow south, forming the eastern-ocean boundary currents. To replace that warm water, cold water rises from the depths — a process called upwelling. Surface ocean currents can occur on local and global scales and are typically wind-driven, resulting in horizontal and vertical water movement. As it continues its journey heat from the ocean is lost to the atmosphere, warming the air Map of Labrador Current. Since density is a function of the temperature and salinity of seawater, the density-driven ocean currents system is known as thermohaline ocean circulation.
