Project summary
The main scientific objectives of project ORFOIS were to:
- identify and quantify globally the mechanisms underlying the transformation of biogenic particles to dissolved substances within the ocean water column in order to predict correctly surface ocean carbon dioxide sources and sinks;
- develop a refined particle flux model for operational use in ocean general circulation models which realistically describes particle dynamics in the water column, deposition of material to the sediment, and the interaction with the carbon dioxide partial pressure pCO2;
- provide a global closed carbon and nutrient budget for modern (preindustrial) conditions including the water column sediment interaction;
- estimate the changes in CO2 sea surface source sink patterns and vertical redistributions of carbon as well as nutrients for future global change, climate change as well as carbon sequestration scenarios including the associated potential economic impacts.
