Located in Northwestern France, the Bay of Brest constitutes a coastal macrotidal and semi-enclosed ecosystem marked with fast mixing exchanges with the Atlantic Ocean through a narrow and deep channel to its west-side. To study the intensity of current in small coves, two moorings were deployed with ADCP on the seabed and temperature sensors at different levels. They were first put in the « Anse de l’Auberlac’h » (A) and the « Anse du Fret » (B) for one month and then move to « Lomergat » (C) and the « Anse du Roz » (D) for another month. More detailed informations is given in the deployment sum-up table.

ADCP data were processed with WinADCP software and filtered in order to get 10 minutes average data.
