Leaving Saint-Maxime-du-Mont-Louis, we set sail for the next leg of our voyage, but due to the low wind we made adjustments. For the first time we rised the main sail and practiced tacking in the tidal current, observing the wildlife around us – gray seals, dolphins and the Northern gannets that began to appear. But most importantly, we were able to make an oceanographic section from 4 casts on the traverse of Cap de la Madeleine. Despite the rather strong drift of the CTD measuring system under the conditions of tidal currents, we reached a depth of 30-50 m, finding the depth of the thermo- and haloclines at a depth of 25 m.
