Evolution of the ice cover through summer. A: Location of the ice edge at a given doy. B, C, D, E: Ice concentrations at doy 160, 175, 190 and 195, respectively. Note the non-linear color scale for the ice concentration. For reference, panels B to E also show the hydrographic station grid. Grey lines indicate isobaths at 250 and 500 m; see Figure 1 for more information on the bathymetry. The yellow star indicates the location of the 2015/2016 ice camps.
