 Although there are no Coriolis forces present along the equator, upwelling still occurs just north and south of the equator.This results in a divergence, with denser, nutrient-rich water being upwelled from below, and results in the remarkable fact that the equatorial region in the Pacific can be detected from space as a broad line of high phytoplankton concentration.Large-scale upwelling is also found in the Southern Ocean.
