Sargassum detection & monitoring
Since 2011, huge sargassum mass strandings have occurred in the wider Caribbean region threatening marine life, affecting human health, impacting tourism and proving to be a costly nuisance for fishing & aquaculture.
Towards an operational solution
In 2018, CLS and NovaBlue Environment (NBE) have been awarded a contract with the European Space Agency (ESA) to develop and test an operational, automatic forecasting system for sargassum management.
While this project is underway and for information purposes only, CLS provides daily images of sargassum floating algae index (FAI).
For more information and access to the operational service, please contact us.

The red shows high concentration of Sargassum. The blue shows low concentrations. The white shows waters without any Sargassum detection (due to an absence of sargassum, excessive cloud cover or being outside the processed area).

These bulletins provide a general outlook on sargassum probability in the Caribbean Sea. By no means should they be used for commercial purpose, or to predict sargassum presence for a specific location or beach.
