Session short summary:
The oceanic biological carbon pump (BCP) transfers organic carbon from the surface to the deep ocean, regulating atmospheric CO₂ and climate. A major uncertainty is marine snow sinking velocity, which varies with particle properties and is affected by vertical ocean velocities (~1 mm/s). We invite studies combining observations, experiments, and modelling to improve BCP representation.
