Dear all
Since May, 2011, a huge amount of pelagic sargassum piles up along the
coast of Martinique and Guadeloupe in the Lesser Antilles, and might
affect probably all the islands in the area.
Tons of algae enter the bays and cover the beaches. This accumulation of
floating sargassum can also extends at the surface of the water for tens
of meters in semi closed area, causing environmental problems to very
coastal communities.
We have not seen any comments since this began in May. The algae still
accumulates and cause management problems for local authorities. This is
also the marine turtles' nesting period, what has an incidence on local
decision to remove the algae accumulated on the beaches. Those algae
decomposed and toxic gaz might be produced, as H2S, which is quite low
from the measures that have been done at the moment (0-3 ppm).
Is there any information we could share on the origin of this
proliferation of pelagic sargassum in the area?
Who else in the Lesser Antilles or elsewhere face the same problem?
We do airplane survey and fly over the coastal area to detect piles of
sargassum away offshore looking at possible trajectories.
We are interested in any satellite images that could detect those saragssum.
Thanks
Jean-Philippe Maréchal
