Coastal Environment under Sargassum crisis

Acronyme du projet CESAR
Montant du financement 1,5M euros
Description succincte du projet Since 2011, pelagic Sargassum strandings in the Caribbean basin have had significant environmental, health,economic and socio-political consequences and a substantial impact on tourism. Research so far tends to confirm the existence of a new ecosystem subjected to movements of water masses across the equatorial Atlantic. The phenomenon occurred in 2011 and the 2012-2018 period, along with increases in Sargassum biomass. Satellite imagery is used to detect Sargassum rafts in the equatorial Atlantic at medium resolution. Sea surface current data for the same area are used to infer annual passive drifting. The combination of these two data sources have made it possible to design coarse-scale approximate prediction tools that remain, however, difficult to operate at the scale of insular coastal zones. This context makes it more difficult to manage Sargassum influxes. The CESAR program will describe and explain the dynamics of coastal Sargassum flows at local spatial scales, their impacts on Caribbean coasts and the various paths explored by political institutions to address this environmental issue. This implies improving knowledge on local forcing parameters and Sargassum dynamics in the Lesser Antilles. CESAR will also work in the possible causes of the Sargassum augmentation in Amazonian context, delivering operational systems to prepare communities and governments to the mitigate this problem.
