BN001:
A Multidisciplinary Approach to the Biological Carbon Pump: Understanding its Efficiency and Predicting its Future


Session ID#: 27937

Session Description:
The biological carbon pump (BCP) transports organic carbon away from the atmosphere to the deep-ocean and sediments, influencing atmospheric CO2levels. The efficiency of the BCP — ratio between fluxes to the deep ocean and primary productivity in the surface ocean — has been intensely studied for the past four decades. Multiple mechanisms contribute to the flux of organic matter to the ocean interior. Recently it has become increasingly clear that complex ecosystem interactions such as phytoplankton community composition and heterotrophic food webs, rather than primary production alone, influence the ability of the oceans to sequester organic carbon. Yet, the mechanisms controlling both the magnitude of carbon export and its fate in the ocean mesopelagic zone are not well understood and a multidisciplinary approach is needed to improve our understanding of these processes. We encourage submissions of field, experimental and modelling studies focusing on:

  • Innovative techniques and models to quantify BCP efficiency
  • Ecosystem processes (e.g. bloom phenology, plankton physiology, particle properties, controls on particle sinking rate and remineralisation)
  • Reconciliation of the discrepancy between POC sinking out of the surface ocean and carbon demand in the dark ocean.
  • Budget calculations and models that predict future BCP in a changing climate
