Monthly mean of backscattering coefficient (bbp) at 490nm (2002-2012) for coastal areas, at global scale, for MERIS sensor, with POLYMER atmospheric corrections. Ref: Loisel in prep.

The activity calendars of fishing vessels reconstituted each year provide access to the following monthly fishing data: main operating port, number of pepole on board, number of days at sea and of, trade (s) practiced ( s), exploited fishing areas and their distance from the coast. Annual data on the dimension and mesh size of the engines used to practice a trade are also provided.

Monthly mean of absorption coefficient minus water absorption (anw) at 412nm (2002-2012) for coastal areas, at global scale, for MERIS sensor, with POLYMER atmospheric corrections. Ref: Loisel (in prep)

La donnée contient la zone d'expansion maximale de la beauxite dans le canyon de Cassidaigne et du domaine bathyal environnant.

"Zones homogènes de dragages" contient la donnée surfacique obtenues à partir des données créés par le BRGM, le CEREMA et issues d'un nombre limité de GPM.
