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)
Ptéropode : Ce petit escargot de mer (le ptéropode Limacina helicina) joue un rôle important dans la chaîne alimentaire et le fonctionnement de l'écosystème marin Arctique. Sa coquille calcaire constitue une protection vitale. Or, une étude montre que cet escargot construit sa coquille à une vitesse 30 % plus faible lorsqu'il est maintenu dans une eau de mer ayant les caractéristiques chimiques attendues pour la fin du siècle.© S.

Sea Urchin - Planktonic Origins
Barely visible to the naked eye, sea urchin larvae grow and transform into bottom-dwelling urchins.

Phytoplankton bloom observed in the Barents Sea (North of Norway) in August 2010 by the ocean color sensor MODIS onboard NASA satellite Aqua. Changes in ocean color result from modifications in the phytoplankton composition and concentration. The green colors are likely associated with the presence of diatoms. The shades of light blue result from the occurrence of coccolithophores, phytoplankton organisms that strongly reflect light due to their chalky shells - Source : NASA's Earth Observatory (http:/earthobservatory.nasa.gov)
