The Restless Oceans 23.5

Explain how the properties of ocean water change with depth.

Atmosphere & Ocean Circulation Atmospheric Circulation Depends on density Ocean Surface Circulation Depends on the wind Deep Ocean Circulation

Why is Ocean Circulation Important? Transport ~ 20% of latitudinal heat Equator to poles Transport nutrients and organisms Influences weather and climate Influences commerce 4 th century BC ,Pytheas of Massalia, a Greek ship captain, explored eastern Atlantic Okeanos (Greek for “Great River”) because he found the ocean flowing south (Canary Current) and thought it was a river too wide to cross.

Ocean Circulation

Distinguish between surface currents, deep currents, and upwelling.

Wind-drive ocean surface currents Wind driven surface currents Wind-drive ocean surface currents London = 51 deg N James Bay = 51 deg. N Edinburgh = 55deg N, same latitude as Ontario’s Polar Bear Provincial Park Total water in ocean surface circulation = about 100 Amazon Rivers (20 million m3/s). It requires 500-2000 years to complete cycle. How fast? A few miles/hr (Gulf Stream off of Miami = 4.5 mph) How much? Total water in ocean surface circulation = about 100 Amazon Rivers (20 million m3/s).
