Altimetry and phytoplankton

More than forests this phytoplankton is producing the oxygen and recycling carbon. It is also the first element of the ocean food chain. Joint observations from infrared (ocean color) and altimetry satellites are very interesting for their understanding.

Sudden phytoplankton blooms are seem on ocean color images (here from the Vegetation sensor onboard Spot, between Africa and Madagascar). Those blooms can be correlated to the eddies and currents seen by altimetry. (Credits CLS).
