Reporting Site: Pelagic Sargassum in the Caribbean
Since 2011 massive quantities of pelagic Sargassum have occurred throughout the Caribbean, impacting aquatic resources, fisheries, shorelines, waterways, and tourism.
In the effort to better understand critical aspects of this phenomenon, this website serves as a data collection center to accommodate reports of large quantities of pelagic sargassum observed within the region during 2016. The website provides easy access for data entry and represents a service to those interested in contributing to the information database. Data provided to this site will be used by Gulf Coast Research Laboratory (GCRL) scientists and colleagues throughout the region to identify the source and examine the movements and causes of this extraordinary event.
