Short description

Our research is focused at the physical, chemical, and biological constraints that regulate and link small-scale (single cell level) and large-scale processes (sinking aggregates of phytoplankton sinking hundreds of meters a day) that govern the oceans biological carbon pump.

Our research is mostly experimental, both in the laboratory and in the field, where we aim at a mechanistic understanding of carbon and nutrient fluxes in plankton communities and their contributions to the biological carbon pump.

To do this, we combine various approaches including stable isotopic tracers and mass spectrometry (EAIRMS, SIMS, GC-EAIRMS), microsensor techniques, and modelling.
