Dear Jean-Philippe,
Is there any more information you can share on the fishermen reports of unusual oceanographic conditions? Or is there data, a report or overview on these changes available elsewhere?
I am in 100% agreement with your hypothesis that the influx of Sargassum is more related to changes in oceanography (perhaps climate change induced?) than to a sudden proliferation of the algae.
Best,
Arlo Hemphill
