Embryos and larvae
Drifting in the currents, embryos and larvae perpetuate the species and are food for multitudes.

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.

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).

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)
