Surface currents

Driven by wind, Coriolis Effect, and Ekman's Spirals

Thermohaline Circulation

Driven by temperature and salinity gradients

Coriolis Effects causes winds and water to move to the right in N hemisphere or left in S hemisphere

Ekman's Spirals are the change in direction of water relative to levels above it (45 degrees to left or right)
