Atlantic sediment polycyclic aromatic hydrocarbon (PAH) concentrations from samples collected using a multi-corer and box corer from multiple cruises throughout the Atlantic between 1994 and 2010

These data include sediment polycyclic aromatic hydrocarbon (PAH) concentrations. 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.

Polycyclic aromatic hydrocarbon concentrations were determined by gas chromatography mass spectrometry. A total of 24 PAH analytes were quantified using ChemStation software. These data help better constrain pyrogenic carbon sources and PAH accumulation rates into Atlantic sediments.

These data were published in St.Laurent, et al. (2023).
