Past calls for proposals
Prior to 2010, Sargassum brown algae bloomed only in the tropical North Atlantic, in the Sargasso Sea. Currently, it has been observed off the Brazilian coast, as far as the Mexican coast and throughout the Caribbean Sea. At the same time, in the western Atlantic, it is flourishing on the African coasts, from Sierra Leone to Ghana, creating the Atlantic Sargassum Green Belt (ASGB) with some continuity between the eastern and western parts. Questions of the influence of climate change on changes in hydrodynamic conditions in the equatorial zone and possibly on changing wind and precipitation drift patterns are not elucidated in relation to the increase and geographic shift in ASGB.
