Abstract

This dataset contains data obtained by the interpretation of mass spectra from the APPI-P FTICR-MS analysis of the selected sediment cores from the northern Gulf of Mexico. This includes i) exact m/z of the identified glycerol ether lipids’ peaks in the sediment extract from the SW01 sampling site and assigned elemental formulae of those peaks; and ii) the intensities of the peaks of the main core glycerol dialkyl glycerol tetraethers species commonly used in (paleo)environmental reconstructions.

Supplemental Information

SW01 (Lat: 28.239717, Lon: -89.120667, collected on: 2014-08-23) and DWH01 (Lat: 28.724367, Lon: -88.387283, collected on: 2014-08-25) are the names of the sampling sites from which the cores were obtained; APPI-P is atmospheric pressure photoionization in positive mode; FTICR-MS is Fourier transform mass spectrometry; mass to charge ratio (m/z); corresponding intensity (I); section of the core analyzed (mm); elemental formula; || Fourier transform ion cyclotron resonance mass spectrometer (FTICR-MS)|||

Purpose

In this study, we demonstrate results of screening of glycerol ether lipids in the whole solvent extracts of recent marine sediments from the Gulf of Mexico using atmospheric pressure photoionization in positive mode (APPI-P) coupled to ultra-high resolution FTICR-MS. It enables rapid and unequivocal identification of a broad range of core GDGT species containing different numbers of alicyclic rings, including their hydroxylated analogs.
