Abstract:

On 2016 a coastal survey was conducted in the Bay of Campeche (Mexico) to search for remnants of the Ixtoc-1 spill. This spill occurred on June 3 of 1979 releasing about 3 million barrels of oil during 9.75 months. In the aftermath of the spill (1979-1980), a survey conducted by Texas A&M University-Corpus Christi indicated oil reached and impacted several areas, including mangroves, reefs and rocky beaches. Previous visual surveys and observations from locals confirmed the coastal areas were not impacted by oil before the Ixtoc-1 spill. In 2016, C-IMAGE II researchers conducted a similar survey with the additional goal of collecting oil-containing samples to investigate (1) the chemical composition and concentration of residual petroleum hydrocarbons, (2) buried oil weathering products, (3) photo-oxidation vs degradation weathering processes, and (4) fate and potential toxicological impacts. This dataset contains hydrocarbon concentrations. The measurements of hydrocarbons were made using Agilent 7680B gas chromatograph coupled with an Agilent 7010 triple quadrupole mass spectrometer.
