Since 2011, caribbean and west-agrican coasts are experiencing huge - and problematic - arrivals of seaweeds (Sargassum spp.).
Changes of atmospheric and oceanic circulation are observed in the altlantic ocean, such as modifications of the main streams and increases of sea surface temperature, of upwellings, of sedimentary contributions of major rivers (amazon, congo) or of sands brought by the winds from the sahara, etc.
Has anyone have an schematic or a synthetic explanation on how the atlantic is changing and why theses changes are impacting sargassum blooms and arrivals on caribbean and african coasts ?
