Abstract:

Dissolved organic carbon concentrations were measured from water samples collected at various stations in the Northern Gulf of Mexico during GISR Cruise G01 (July 2012) and G03 (November-December 2012). Both cruises were on the R/V Pelican, cruise codes PE13-01 and PE13-15 respectively. Results from the G01 cruise together with other data comprise the support for the paper titled "Deepwater Horizon Oil in the Gulf of Mexico Waters after Two Years: Transformation into the Dissolved Organic Matter Pool" by Bianchi et al. 2014 in Environ. Sci. Technol., 2014, 48 (16), pp 9288–9297 DOI: 10.1021/es501547b
