Research on marine macroalgae (seaweeds). Scientific contributions to the understanding of littoral ecosystem functioning through field sampling and remote sensing.

Research Focus::

Study of the invasion dynamics of Sargassum muticum in the Bay of Seine through three actions:

• Analysis of Sargassum proliferation: Monitoring of Sargassum populations by in-situ sampling (intertidal and subtidal). Quantitative and qualitative analysis of beachings (strandings).
• Development of remote sensing tools to map and assess the biomass of Sargassum in open water and when beached.
• Evaluation of Sargassum as an indicator of coastal water quality related to eutrophication.
