Average chlorophyll concentration in the surface ocean (from mi-September 1997 to August 2007) from the ocean color sensor SeaWiFS (NASA). Subtropical gyres, in the center of the oceanic basins, are characterized by very low concentrations of chlorophyll a (dark blue) - Source : NASA's Earth Observatory (http:/earthobservatory.nasa.gov)

Surface chlorophyll a concentration in the global ocean.

Rosette used to collect seawater samples during a scientific cruise in the South Pacific Ocean. During the austral summer, the amount of chlorophyll a is so low that the water becomes deep blue, almost purple. (Photo : Joséphine Ras)
