Carbon cycles of the Anthropocene oceans

Research group based at CEREGE, Aix-en-Provence, France

Welcome to the DEEP-C.

We are a research group primarily interested in the carbon cycles in the Anthropocene’s oceans. We use numerical models, laboratory experiments and in-situ observations to understand how sediments and organisms at the seafloor, a mostly unmapped environment that covers more than two thirds of our planet surface, regulate the climate of our planet. Our research also explores deep-sea currents, waves and tides, marine snow, and accurate predictions of seawater carbon species composition.

Main questions that drive our research

  • In what extent are deep-sea environments entering the Anthropocene? 
  • How can humans mitigate climate change inspiring from natural, ocean-based processes? 
  • How are marine calcifying organisms affected by global changes?
  • How are human activities altering the sediment record? 

What we do, and how we do it, in a few pictures:
