  1. The role of the ocean in global change J.-P. Vanderborght ULB, Océanographie Chimique et Géochimie des Eaux (ULB-OCEAN)

  3. Context • During recent geological time, the ocean was a source of CO2 for the atmosphere. • Following the modern increase of atmospheric CO2, the ocean acts now as a sink, with a net uptake of 2 to 3 gigatons of C per year. • ~ 30 % of the total CO2 emitted by man has been transfered to the ocean.

  6. Some key contributions • Behaviour of nutrients in estuarine and coastal systems (N – P – Si ) • Direct measurement / modeling of CO2 exchange at the sea surface

  7. Evaluation of C fluxes in estuaries, coastal zones and the continental shelf, in the water column and in the sediments

  8. Evaluation of organic carbon fluxes along the continental margin and in the Southern ocean

  9. Role of siliceous and calcareous organisms • Assessment of iron fertilisation in the Southern ocean • Development of new tools: databases, indicators, models

  10. At the individual level: International Scientific Committees and Research Institutes, etc. At the institutional level: the role of MUMM at the interface between science and the society. Belgian marine research: a long tradition of collaboration between scientists and policy preparing fora
