Equally important, they are working to advance scientific and technical cooperation to support the implementation and development of monitoring and forecasting systems, promoting their use and the use of FAIR (Findable, Accessible, Interoperable, and Reusable) data.<\/p><p>One of the Working Group\u2019s key activities is the Sargassum Information Hub. Created in collaboration with partners including the IOCARIBE of IOC-UNESCO, AtlantOS, and the Atlantic International Research (AIR) Center, the Hub acts as a centralised point for the latest information on Sargassum, Sargassum-related news and events, a project directory, and Sargassum monitoring and forecasting information, and more. The Hub will be updated with a new directory dedicated to the different actors in the Sargassum value chain.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ebeb945 elementor-align-left elementor-widget__width-inherit elementor-widget elementor-widget-button\" data-id=\"ebeb945\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/geoblueplanet.org\/sargassum\/\" target=\"_blank\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Sargassum Working Group<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a8bc438 elementor-widget__width-inherit elementor-widget elementor-widget-heading\" data-id=\"a8bc438\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">SargCOOP2<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9e0263c elementor-widget__width-inherit elementor-widget elementor-widget-text-editor\" data-id=\"9e0263c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>SargCOOP2 is a project supported by GEO Blue Planet which participates in many different activities such as deploying coastal current tracking devices in nearshore waters in collaboration with Mercator Ocean International, CLS, French Space Agency CNES and CNP a subsidiary specialising in Earth Observations.<\/p><p>Other SARGCOOP2 activities GEO Blue Planet supports are the inclusion of a dedicated SARGCOOP Community Cluster in the Sargassum information Hub, which will act as a central repository for all of the project\u2019s information and bring the SARG\u2019COOP community together and provide scientific insights as and when needed.<\/p><p><strong>Read more news:<\/strong><\/p><ul><li><a href=\"https:\/\/geoblueplanet.org\/turning-the-tide-on-sargassum\/\" target=\"_blank\" rel=\"noopener\">Turning the tide on Sargassum at SARG\u2019COOP II &#8211;
