Remote monitoring of turbidity and phytoplankton biomass in French Maritime Sub Regions

Daily maps of chlorophyll, mineral materials in suspension and turbidity (in addition to the KPAR attenuation coefficient) in photosynthesis wavelength) are drawn up from marine reflectance data (water colour) provided directly by space agencies (NASA, Agence Spatiale Européenne, EUMETSAT), or by the MyOcean/GMES project on which Ifremer collaborates. Multi sensor maps are also offered by interpolation in order to provide information, even in the presence of cloud cover. Reflectance data is processed by Ifremer algorithms and will enhance an archive which began in 1998. The data is continuously validated thanks to in situ measurements which are mostly provided by equipped buoys or the REPHY network.
