Data Center Description
One of the most challenging issues addressed to the oceanographic community is to budget atmospheric CO2 fluxes over the oceans. The open ocean has a major role in the global CO2 cycle, since it absorbs about 29% of the anthropogenic CO2 inputs (that contribute to 57% of the greenhouse forcing among all radiative gases). So far, one of the best methods is to compile worldwide measurements of the partial pressure of CO2 (pCO2) and to compute related CO2 fluxes using wind speed and well-constrained gas transfer velocity relationships. However, due to the large spatio-temporal variability of pCO2, budgeting CO2 fluxes requires huge data sets which cover satisfactorily both spatial and temporal changes.
The Chemical Oceanography Unit of the University of Liège aims to fill two crucial gaps in the present knowledge of global CO2 fluxes: the ignored Coastal Ocean and the remote Southern Ocean thought as the "last oceanic sink". In parallel, the Chemical Oceanography Unit also investigates the potential feed-backs between the oceanic biota and climate and their impact on global CO2 cycling.
