Monitoring Sargassum: Europe moves into operational mode

Sargassum seaweed is a scourge for health, fishing and the tourist economy in the Caribbean. Piling up on beaches and forcing boats to stay in harbour, this brownish algae is closely monitored by CLS teams. How can we detect algae mats and predict where they will drift and be washed ashore? This is the challenge

Models to understand the dynamic and periods of litter accumulation

Plastic in the marine environment is a growing issue. If most of the marine plastic debris are in micro plastic form, the most feasible way to collect these litters is when still in macro form, and as close to the sources on land as possible to make retrieval cheaper and the pollution easier to collect.
