Les Dinoflagellés - Ceratium hexacanthum
chaîne de Ceratium hexacanthum qui restent les uns à la suites des autres au fur et à mesure des divisions.
Le mouvement des flagelles est bien visible.
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)
This video describes how to perform the Ludion experiment and explains the physical processes involved.
