3. OCEAN LAYERSSURFACE MIXED ZONE – less dense upper ocean, temp and salinity change oftenTRANSITION ZONE – fairly constant density, acts as barrier between surface and deep zones - PYCNOCLINE – rapid density change in water column - THERMOCLINE – rapid temp change in water columnDEEP ZONE – water remains cold and denseTransition

5. THERMOHALINE CIRCULATION Movement of masses of ocean water driven by density gradients due to surface heat and freshwater input
6. SURFACE CURRENTSGYRES – large systems of spinning currents caused by the Coriolis effect
7. CORIOLIS EFFECT
8. Ekman transportAn Ekman spiral (A) is a rotating column of water that forms when water moves at an angle to the wind direction due to the Coriolis Effect. The net effect of the rotating water (B) is movement at 90° to wind direction. Water turns to the right in NH, and to the left in SH.
