Bringing together regional and international partners, the GEO Blue Planet Sargassum Working Group is supporting the development of monitoring and early warning systems for Sargassum across all affected regions of the Tropical Atlantic.

One of the Working Group’s key activities is the Sargassum Information Hub. Currently, the Hub is undergoing an update to make information more accessible. For example, alongside English and French, the updates will see the Hub available in Spanish and Portuguese.

GEO Blue Planet is also working on the second phase of the Caribbean Sargasso (SARG’COOP) programme.

In 2019, SARG’COOP was launched to enhance Caribbean territories’ preparedness and resilience to Sargassum blooms. Among the programme’s achievements was establishing a Caribbean centre for the prevention and monitoring of Sargassum algae. The first phase of the project ended in 2023, but in March 2025, the second phase (SARG’COOP II) was launched in Guadeloupe.

The second phase will focus on four key areas: scientific research to improve our knowledge and understanding of sargassum dynamics, improving detection and tracking of sargassum blooms, developing better management approaches to Sargassum, and exploring ways to repurpose Sargassum sustainably.
