Daily temperature at a depth of 5 m on two ropes moored at a water depth of 30 m and 60 m, respectively, at Miquelon Bay outlet Positions of site B and C are available in the map attached Vertical profiles of salinity from a CTD cast run at site D (associated map) were performed at water depth of 0-40 m on 04/08/2010, 15/09/2010, 04/10/2010, and 16/11/2010. Measurements were taken at 10 s intervals. We assessed the mean salinity at this time of the year between 0 and 5 m. These data are discussed in Poitevin et al. 2018 submitted to Plos One This work was supported by the EC2CO program MATISSE of the CNRS INSU, the Cluster of Excellence LabexMER, and the LIA BeBEST CNRS INEE. This research was carried out as part of the Ph.D. thesis of Pierre Poitevin for the University of Western Brittany with a French Ministry of Higher Education and Research grant.
