Massive quantities of pelagic sargassum have been washing up along Caribbean shorelines this year, significantly disrupting local fishing, tourism and community activities. This ongoing event recently received considerable attention via the GCFINET LISTSERV. Those correspondences are providing extremely valuable information on this region-wide phenomenon.

 Scientists with the University of Southern Mississippi – Gulf Coast Research Laboratory (GCRL) and their collaborators are assessing critical aspects of this event (as with the 2011 Caribbean mass sargassum strandings event), including the source and causes. In 2012 the GCRL developed a website (with user-friendly online reporting form) designed specifically to accommodate the reporting of large quantities of pelagic sargassum throughout the Caribbean region. This site serves as a data reporting/collection center and represents a service available to individuals, organizations and fisheries agencies throughout the region for contributing their

Without them and other herbivores, algae and seaweed would overgrow the reefs, suppress coral growth and threaten the incredible array of life that depends on these reefs for shelter and food.

This was happening in Bermuda, until the government in 1990 banned fish traps that were decimating the parrotfish population. Today, Bermuda's coral reefs are relatively healthy, a bright spot in the wider Caribbean, where total coral cover has declined by half since 1970.
