Ocean Currents

This is an image of how upwelling occurs. Upwelling is important to organisms because...

• when local wind patterns blow along the north west coast, they cause local surface currents to move away from the shore.
• upwelling causes warm water to flow to the British Isles and creates a mild climate there.
• upwelling brings nutrients to the surface of the ocean to support the growth of phytoplankton and zooplankton.

A horizontal movement of ocean water that is caused by wind and that occurs at or near the ocean's surface.

• Gulf Stream
