Temperature, salinity, dissolved oxygen, suspended particulate matter and fluorescence in surface waters of the Charente estuary (North East Atlantic, France)
There are at least a dozen small hyper-turbid estuaries facing the Bay of Biscay, geographically situated between the two major estuaries of the Gironde and the Loire. MAGEST and SYVEL high-frequency multi-site monitoring revealed that the Loire, and to a lesser extent the Gironde, are subject to su...
