[Atlantic Sediment Black Carbon] - Atlantic sediment black carbon, total organic carbon, and stable carbon ratio (13C) values from samples collected using a multi-corer and box corer from multiple cruises throughout the Atlantic between 1994 and 2010 (Concentrations and source assessment of black carbon across tropical Atlantic air and sediment)

These data were collected on multiple cruises in throughout the Atlantic; specifically, in the Amazon Delta (EN-480; July 2010), Sierra Leone Rise (EN-481; August 2010), Niger Delta (GeoB 4901, GeoB 4903, GeoB 4904, GeoB 4905, GeoB 4907, and GeoB 4908; February/March 1998), Senegal Delta (GeoB 9501; April/May 2003), and Northwest Argentina Basin (GeoB 2814; July/August 1994).

Sediments were collected using multi-corer and box corer samples and kept frozen until analysis. Total organic carbon and black carbon concentrations and stable carbon ratio values were determined on an isotope ratio mass spectrometer coupled to an elemental analyzer. The black carbon fraction was determined using the chemothermal oxidation at 375°C method.
