How Do the Carbon Pumps Pump? Mechanisms of the Solubility and Biological Pumps III Posters

Session ID#: 7590

Session Description:
Cumulatively since pre-industrial times the ocean has absorbed 40% of anthropogenic carbon emissions, and thus has significantly modulated climate change. The ocean’s carbon uptake is mediated by subduction of carbon rich water (solubility pump) and by the export to depth of organic particles and dissolved organic carbon (biological carbon pump). There is much yet unknown about the underlying biological, chemical and physical mechanisms of these pumps, and thus, substantial uncertainty about the how ocean carbon cycling will evolve over the coming century. Developments in sensor technology, particle export techniques, global data compilations, time series observations, and modeling all are enabling new understanding of the carbon pumps and their potential for variability and change. Observational, experimental, empirical and modeling studies addressing the ocean carbon pumps are welcomed to this session.
