Outlook of 2020 Sargassum blooms in the Caribbean Sea* July 31st, 2020, by University of South Florida Optical Oceanography Lab (huc@usf.edu)

The maps below show Sargassum abundance, with warm colors representing high abundance. In July 2020, the overall Sargassum amount decreased across the central Atlantic. This is unusual, as in previous years July often had higher amount than June. Yet large amount was still observed in July 2020 in the Central West Atlantic (CWA, i.e., the… Read More

Experimental Weekly Sargassum Inundation Report (SIR v1.2) By the National Oceanic and Atmospheric Administration (NOAA), and the University of South Florida (USF) – Status: Jun 16-22, 2020

Since 2011, large accumulations of Sargassum is a recurrent problem in the Caribbean Sea, in the Gulf of Mexico and tropical Atlantic. These events can cause significant economic, environmental and public health harm. These experimental Sargassum Inundation Reports (SIR) provide an overview of the risk of sargassum coastal inundation in the Caribbean and Gulf of… Read More
