Objective

Series of campaigns realized to answer the questions raised by Sargasso algae proliferation in tropical north Atlantic, responsible for massive strandings upon American, African and Caribbean coasts since 2011. Objective: sampling of Sargasso, of the fauna and flora associated with Sargasso rafts, and in situ measurement of environmental parameters.
