Main lines of research

Observation and study of long-term variations in the pelagic ecosystem. Time series.

• Changes in abundance and diversity of plankton and micronekton as a function of the environment.

The role of plankton and micronekton and their diversity in biogeochemical cycles and food webs.

• Biomass, composition and dynamics of the different components.
• Trophic networks. Biomass transfer. Recycling vs. export.
• Biogeochemistry: C, N, P and Si cycles. Biological pump.

Ecology and evolution of plankton.

• Theoretical ecology and numerical simulations focused on ecological niches and future scenarios.

Deep-sea benthic ecology, diversity and conservation.

• Vulnerable deep-sea marine ecosystems, cold water corals.
• Distribution, ecophysiology, functionality, benthic-pelagic coupling, associated diversity and conservation

Development of underwater acoustic methodology.

• Development of algorithms and processing for echogram cleaning, noise estimation, species identification, target strength, data reduction, broadband, deep acoustic profilers, multibeam…
