Transport ~ 20% of latitudinal heat Equator to poles Transport nutrients and organisms Influences weather and climate Influences commerce Temperature Structure of Ocean : Temperature Structure of Ocean thermocline Ocean Circulation : Ocean Circulation Wind-drive ocean surface currents : Wind-drive ocean surface currents Wind driven surface currents 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). Atmosphere & Ocean Circulation : Atmosphere & Ocean Circulation Atmospheric Circulation Depends on density Ocean Surface Circulation Depends on the wind Deep Ocean Circulation Depends on density Sea Surface Temperature : Sea Surface Temperature http://www.ldeo.columbia.edu/dees/ees/climate/slides/sst_march.gif Ocean Salinity : Ocean Salinity http://www.ldeo.columbia.edu/dees/ees/climate/slides/sal_march.gif http://ingrid.ldgo.columbia.edu/ Temperature-Salinity (density) Diagram : Temperature-Salinity (density) Diagram Thermohaline Circulation : Thermohaline Circulation North Atlantic Deep Water (NADW 15 million m3 of near surface water descend into the deep ocean each second. Thermohaline Circulation - The Ocean Conveyor : Thermohaline Circulation - The Ocean Conveyor Equatorial to polar heat transport and water flow : Equatorial to polar heat transport and water flow Ocean – Atmosphere Circulation : Ocean – Atmosphere Circulation UNEQUAL HEATING OF EARTH : UNEQUAL HEATING OF EARTH BUT – Outgoing solar radiation is not as uneven You do not have the permission to view this presentation.
