Anthropogenic carbon transports at 26N as estimated using the RAPID-MOCHA-WBTS (RAPID-Meridional Overturning Circulation and Heatflux Array-Western Boundary Time Series) array for 2004 to 2012.

Estimates of anthropogenic carbon derived from hydrographic cruise occupations at 24.5N have been combined with volume transport estimates produced by the RAPID-MOCHA-WBTS (RAPID-Meridional Overturning Circulation and Heatflux Array-Western Boundary Time Series) programme at 26N to generate a time series of anthropogenic carbon transports between 2004 and 2012. Anthropogenic carbon is calculated using measurements of temperature, salinity, dissolved inorganic carbon, total alkalinity, oxygen, inorganic nutrients and chlorofluorocarbons collected on cruises between the east coast of USA and Africa between 1992 and 2011. The volume transport time series is derived from measurements of temperature, salinity, pressure and water velocity from an array of moored instruments that extend from the east coast of the Bahamas to the continental shelf off Africa east of the Canary Islands, combined with estimates of the transport in the Florida Strait derived from sub-sea cable measurements calibrated by regular hydrographic cruises, and satellite scatterometer measurements (wind driven Ekman transport). This data release includes published paper with a full description of the calculation of anthropogenic carbon fields and their transports, and references to more detailed description of the volume transport time series calculation. The anthropogenic carbon transports form part of the Atlantic Biogeochemical Fluxes programme (Principle Investigator Elaine McDonagh).
