Lineage Images (provided as rasters, 1.2 km cell size, referenced in WGS 1984) were obtained from IFREMER’s CERSAT (located in Plouzané, France) from databases generated for European projects (e.g. MARCOAST, ECOOP). Original data come from the AVHRR/Pathfinder centre (AVHRR sensor) and from NASA (SeaWiFS and MODIS). The best images, i.e. those where the percentage of cloud-free pixels was above a threshold of 25%, were used to calculate monthly averages.
