Mass-to-charge ratio (m/z) and monoisotopic intensity from a sediment core collected aboard the R/V Justo Sierra cruise JS-0815 in the southern Gulf of Mexico on 2015-08-06

This dataset contains exact mass-to-charge ratio (m/z) and monoisotopic intensity peaks detected in the southern Gulf of Mexico sediment extracts using a Fourier transform ion cyclotron mass spectrometry (FTICR-MS) with atmospheric pressure photoionization in positive mode. The instrument used was manufactured by Bruker Daltonics; Model: Solarix, 12T. A 25 µl of 10 mg/mL toluene stock solutions of the total lipid extracts of sediment was diluted to a total concentration of 200 µl and directly infused to the ionization source via syringe at 200 µl/hour flow rate. The analysis was performed on a sediment core (IWX500) collected aboard the R/V Justo Sierra cruise JS-0815 in the Gulf of Mexico on 2015-08-06 at 1010 m water depth. The sediment core was sectioned into five depth intervals (0-5, 68-70, 70-72, 72-74, 195-200 mm). The R/V Justo Sierra cruise JS-0815 was led by chief scientists Dr. David Hollander and Dr. Patrick Schwing. The goal of this cruise was to characterize the distribution and fate of oiled sediment at sites on the continental shelf and slope of the southern Gulf of Mexico with reference to the Ixtoc blowout (1979-1980).
