Document Summary
Five large western boundary currents (hot water currents: the gulf stream, the japan or kuroshio current, the brazil current, the agulhas current (indian ocean, the east australian current, west boundary of ocean basin. Five large eastern boundary currents (cold water currents: the canary current (north atlantic, the benguela current (south atlantic, the california current, the west australian current, the peru and humboldt current (south pacific, east boundary of ocean basic. 2-density differences causes vertical movement in the water column: upwelling: a process by which deep water is brought to the surface, carries nutrients to the surface layers, high rates of primary production. 3-coastal upwelling: wind-water interaction, transporting water 90 degrees from the direction of the wind due to coriolis effect. 5-equatorial upwelling: surface currents are deflected to the right by the coriolis effect in the northern hemisphere, diverging surface currents pull deep water to the surface, no coriolis effect occurs near the equator.
