North Atlantic across 26.5N from Florida Straits to African coast

Vertical spatial coordinates; Date and time; Transport in the water column

The dataset comprises the combination of estimates of anthropogenic carbon derived from hydrographic occupations of the 26N section with volume transports for the area between east USA and Africa calculated using the RAPID-MOCHA-WBTS AMOC timeseries. The data cover the time period between April 2004 and October 2012. The observations will be used with data from other sources to determine and interpret the accumulation of anthropogenic carbon in the North Atlantic, to infer the magnitude and variability of uptake of anthropogenic carbon dioxide from the atmosphere, and assess the risk of changes in the meridional overturning circulation on the marine carbon cycle. The Atlantic Biogeochemical Fluxes programme (ABC-Fluxes) is a joint effort between NERC in the UK (Principal Investigator Elaine McDonagh), and NOAA in the USA (Molly Baringer). It builds on the work of the RAPID-MOCHA-WBTS programme, a joint effort between NERC in the UK (Principal Investigator Eleanor Frajka-Williams), NOAA (Molly Baringer) and RSMAS (Bill Johns) in the USA. The Atlantic anthropogenic carbon transport (and its components), calculated from the above data, are held by BODC in NetCDF format.
