A la recherche de la nouvelle mer des Sargasses

From June 19 to July 13, 2017, a scientific expedition conducted aboard the ANTEA, a vessel of the French Oceanographic Fleet, enabled a team of researchers to conduct a significant sampling of the fauna and flora associated with "Sargasso rafts." These pelagic brown algae, present in the tropical Atlantic, have been washing up on the Atlantic coast since 2011 due to ocean circulation. They are responsible for significant environmental, health, and economic problems, particularly in the Caribbean arc and French Guiana. Researchers and lecturers from IRD, Aix-Marseille University, the University of the Antilles, and the University of Western Brittany completed a 25-day voyage between French Guiana, the Antilles, and the Sargasso Sea. Discover their work identifying, sampling, and analyzing Sargassum in this film produced by IRD Images.
