90th percentile calculated during the productive period of the WFD (March-October) from 2015 to 2020, from the MODIS Chl-a algorithm processed by OC5 IFREMER/ARGANS (Gohin et al 2002, Gohin 2011).

Average monthly turbidity maps made during the period 2003-2010. Turbidity is estimated from the concentrations of inorganic suspended materials and chlorophyll-a.

90th percentile of turbidity calculated during the productive period of the WFD (March-October) from 2015 to 2020, from the MODIS algorithm processed by OC5 IFREMER/ARGANS (Gohin et al 2002, Gohin 2011).

90th percentile of non-algal suspended matter calculated during the productive period of the WFD (March-October) from 2015 to 2020, from the MODIS algorithm processed by OC5 IFREMER/ARGANS (Gohin et al 2002, Gohin 2011).

Map of average monthly non-algal suspended matter carried out in the period 2003-2010. TSS are estimated from the water reflectance using a specific algorithm developed at Ifremer.

Monthly maps of mean chlorophyll-a achieved over the period 2003-2010. Chlorophyll-a is calculated using the OC5 algorithm developed by Ifremer.
