Corail profond : Pour un niveau d'acidité prévu pour la fin du siècle, une diminution de construction de son squelette de 50 % a été mesurée chez le corail d'eaux froides Lophelia pertusa. Les communautés coralliennes d'eaux froides abritent un grand nombre d'espèces. Une diminution de la croissance des coraux constructeurs par l'acidification des océans peut menacer l'existence même de ces édifices. © C. Maier, LOV

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)

Plankton
Plankton are a multitude of living organisms adrift in the currents.Our food, our fuel, and the air we breathe originate in plankton.
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)
