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)

Large rosette sampler used in the "World Ocean Circulation Experiment". This rosette has 36 10-liter Niskin bottles, an acoustic pinger (lower left), an "LADCP" current profiler (yellow long tube at the center), a CTD (horizontal instrument at the bottom), and transmissometer (yellow short tube at the center).

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)
