Elle a \u00e9t\u00e9 d\u00e9couverte alors que tout l\u2019\u00e9quipage de son exp\u00e9dition commen\u00e7ait \u00e0 trouver le temps long et s\u2019inqui\u00e9tait de toucher \u00e0 nouveau la terre ferme. Elle se trouve au niveau des Bermudes. Mais ce que l\u2019on sait moins, c\u2019est qu\u2019actuellement une nouvelle mer des Sargasses est en train de voir le jour, plus au sud, dans l\u2019Atlantique tropical Nord. C\u2019est tout l\u2019objet des Exp\u00e9ditions Sargasses, organis\u00e9es par l\u2019Universit\u00e9 d\u2019Aix-Marseille et l\u2019IRD (Institut de Recherche et de D\u00e9veloppement), avec le soutien de la Flotte oc\u00e9anographique fran\u00e7aise, de Monaco exploration, des Universit\u00e9s de Bretagne-Occidentale, des Antilles, de Pernabouco (Br\u00e9sil) et d\u2019Abidjan (Cote d\u2019Ivoire).<\/p><p class=\"rtejustify\">A l\u2019origine, les Exp\u00e9ditions Sargasses r\u00e9pondent \u00e0 une pr\u00e9occupation majeure des populations des Antilles fran\u00e7aises qui sont confront\u00e9es, de mani\u00e8re r\u00e9p\u00e9titive depuis 2011, \u00e0 des mar\u00e9es brunes suivies d\u2019\u00e9chouages consid\u00e9rables. Cela provoque des cons\u00e9quences catastrophiques sur la faune et la flore benthique ainsi que sur la sant\u00e9 et les activit\u00e9s humaines. Mais en r\u00e9alit\u00e9, ces \u00e9chouages massifs de Sargasses p\u00e9lagiques sont g\u00e9n\u00e9ralis\u00e9s sur tout le pourtour de l\u2019Oc\u00e9an Atlantique tropical Nord. On les retrouve aux petites et grandes Antilles, sur les c\u00f4tes de Guyane, du Br\u00e9sil et d\u2019Afrique de l\u2019Ouest ainsi sur le pourtour du Golfe du Mexique. L\u2019analyse des images satellite a permis de reconstituer leur parcours depuis l\u2019Atlantique, en face de l\u2019embouchure de l\u2019Amazone, mais l\u2019identification pr\u00e9cise de ces esp\u00e8ces de Sargasses n\u2019est pas connue, et les causes de l\u2019apparition de cette \u00ab\u00a0Nouvelle mer des Sargasses\u00a0\u00bb restent hypoth\u00e9tiques.<\/p><h4
