Scientists probe Saharan dust–sargassum link in Barbados

Scientists in Barbados are exploring a new hypothesis: that dust blown from the Sahara Desert might be fueling the massive sargassum seaweed blooms plaguing Caribbean shores. The Barbados Atmospheric Chemistry Observatory (BACO) is leading the investigation.

Researchers are collecting and analyzing dust samples to determine if they contain nutrients that could promote sargassum growth. Sargassum seaweed has become a persistent environmental challenge for Barbados and other Caribbean nations, washing ashore in vast quantities and disrupting tourism and marine ecosystems.

While the exact causes of the sargassum influx remain complex, understanding the role of Saharan dust could offer crucial insights. This research aims to provide a more complete picture of the factors contributing to the seaweed problem, potentially informing future mitigation strategies.
