Marine environmental station database of Daoulas bay
Located in Northwestern France, the Bay of Brest constitutes a coastal macrotidal and semi-enclosed ecosystem (total area of 180 km2, maximum tidal amplitude of 8 m, average depth of 8 m) influenced by both freshwater inputs from rivers (to its east-side) and fast mixing exchanges with the Atlantic...

Located in Northwestern France, the Bay of Brest constitutes a coastal macrotidal and semi-enclosed ecosystem (total area of 180 km2, maximum tidal amplitude of 8 m, average depth of 8 m) influenced by both freshwater inputs from rivers (to its east-side) and fast mixing exchanges with the Atlantic Ocean through a narrow (1.8 km of wide) and deep (40 m) channel (to its west-side). The average flushing time of the system is around 25 days. The shallowness of the bay and the water mixing induced by tidal currents prevent the ecosystem from vertical stratification and nutrient accumulation and therefore limit eutrophication. This environment is still very rich and shelters numerous species, macrobenthic communities and remarkable habitats (for instance: maerl beds, scallops and brittlestars sandy-shelly muds, flat oysters beds associated with black scallops, slipper limpet mixed sediments, zostera beds, intertidal pacific oyster population.). Nevertheless, this ecosystem is also under the pressure of human activities: the north of the system shelters a population of 400 000 inhabitants whereas the south is more influenced by intensive agricultural activities.
