southern hemisphere. Not gyres because don’t swirl) -Major surface current types -Western Boundary Currents -Fastest, deepest currents on earth -occur on western boundary -move warm water to higher latitude (pole ward) -gulf stream is the largest: -moves 2 m/s -70km wide, up to 450 m deep -flows 55 million cubic meters of water per second (55 sverdrups) -rapid flow keeps current mostly intact -eddies form along edges through turbulence -cold core eddies -warm core eddies -major western boundary currents: gulf stream, kuroshio current, brazil current, agulhas current, east Australian current (EAC) -Eastern Boundary Current -move (mostly) cold water equatorward
