On 27 July, the boat Gwalarn was back to the marina of Lorient after several months in the Atlantic Ocean. It was the opportunity for Calixte to find Julien, the captain of the boat, and to share its experience with Plankton Planet protocol. In total, no fewer than 18 samples have been collected. This valuable collection will join the Roscoff laboratory for analysis. Julien very satisfied with their experience said he was motivated to continue the adventure as soon as possible.
