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).

Seasonal evolution of the chlorophyll a concentration as obtained by the ocean color sensor SeaWiFS in the Atlantic Ocean.
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)

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

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
