International Workshop on 'Aquatic Carbon From Space'. Why: aquatic carbon is a major component of the Earth system in carbon cycling and carbon sequestration. Why now: an international workshop on the Ocean Carbon Cycle is planned in the frame of the ESA BICEP project ( Ocean Biological Carbon Pump ); NASA is also interested in supporting this as it falls within the framework of EXPORTS. Better synchronization with C from Space Special Ed (Item above). What: current state of knowledge of the carbon cycle and the role of aquatic environments;with recent numbers / impact factors;from observations to modeling and applications Themes: carbon stocks;sources/sinks;fluxes; methodology and uncertainty estimates
