Chaque ann\u00e9e, nos plages peuvent \u00eatre confront\u00e9es \u00e0 une augmentation de la prolif\u00e9ration des sargasses de mars \u00e0 octobre, avec un pic g\u00e9n\u00e9ralement observ\u00e9 en juin et juillet. Les sargasses sont une algue brune flottante qui traverse l'oc\u00e9an Atlantique. Bien que leur arriv\u00e9e puisse surprendre les baigneurs, elles jouent un r\u00f4le important dans l'\u00e9cosyst\u00e8me c\u00f4tier et sont quotidiennement retir\u00e9es et g\u00e9r\u00e9es par le comt\u00e9 de Miami-Dade, conform\u00e9ment \u00e0 un permis d'\u00c9tat.<\/p>\n

La lutte contre les sargasses dans le cadre de la r\u00e9glementation est une priorit\u00e9 \u00e0 la fois actuelle et \u00e0 long terme pour la ville de Miami Beach.<\/p>\n\t\t\t\t\t\t\t\t\t\t\t\t\n\t\t\t\t\t\"youtube-video-thumbnail\"\/\n\t

In Miami Beach, seaweed-specifically sargassum-is a type of brown algae that floats on the ocean’s surface thanks to small, gas-filled sacs called pneumatocysts. Common throughout the Atlantic, sargassum often forms large floating mats influenced by ocean currents, wind patterns and changing weather conditions.<\/p>\n

Les sargasses pr\u00e9sentent des avantages environnementaux car elles servent d'habitat \u00e0 la faune marine migratrice, notamment aux crabes, aux crevettes, aux tortues marines et \u00e0 certains poissons. Les petites quantit\u00e9s qui s'\u00e9chouent sur le rivage contribuent \u00e0 la formation et \u00e0 l'entretien des dunes de sable, qui prot\u00e8gent les c\u00f4tes de l'\u00e9rosion, des grandes mar\u00e9es et des temp\u00eates. Elles constituent l'un des \u00e9l\u00e9ments essentiels de l'habitat critique d\u00e9sign\u00e9 pour la tortue caouanne et de l'habitat critique propos\u00e9 pour la tortue verte. Loi sur les esp\u00e8ces menac\u00e9es (ESA)<\/a><\/strong>. Elle sert de zone de nurserie essentielle pour diverses esp\u00e8ces de poissons comme la dorade coryph\u00e8ne, la carangue et la s\u00e9riole. On a \u00e9galement constat\u00e9 qu'elle absorbe les nutriments et s\u00e9questre le dioxyde de carbone, contribuant ainsi \u00e0 att\u00e9nuer l'acidification des oc\u00e9ans et \u00e0 \u00e9liminer les polluants des eaux marines.<\/p>\n

Depuis 2011, la quantit\u00e9 de sargasses atteignant les c\u00f4tes des Cara\u00efbes et de la Floride a augment\u00e9. \u00c0 Miami Beach, d'importantes quantit\u00e9s proviennent g\u00e9n\u00e9ralement de\u2026 De mars \u00e0 octobre. <\/strong>Les satellites peuvent suivre les sargasses en mer, mais la quantit\u00e9 exacte et l'emplacement des sargasses qui s'\u00e9chouent quotidiennement sur nos plages varient en fonction des vents locaux, des courants oc\u00e9aniques et des mar\u00e9es changeantes, ce qui peut entra\u00eener\u2026 \u00c9v\u00e9nements d'inondation par les sargasses (EIS)<\/strong>.<\/a> Lorsque les sargasses atteignent nos plages, elles se d\u00e9composent sur le rivage.
