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?Â
- How can humans mitigate climate change inspiring from natural, ocean-based processes?Â
- How are marine calcifying organisms affected by global changes?
- How are human activities altering the sediment record?Â
