Field Samples: Emulsion molecular-level data collected around three locations in the Gulf Coast from 2010-06-10 to 2014-01-27

This dataset contains field samples data collected near Pensacola, Florida (57 days after the initial spill, and before the well was capped), Gulf Shores, Alabama (586 days post-spill), and Dauphin Island, Alabama (1368 days post-spill) from 2010-06-10 to 2014-11-27. The samples collected from RFP-V State of the art unraveling of the biotic and abiotic chemical evolution of Macondo oil was homogenized and extracted to yield the recalcitrant oil/oil weathering products. The extract was then fractionated into oil-soluble, interfacially active and oil-soluble, and interfacially in-active components. The interfacial material (IM) active species were further fractionated by modified aminopropyl silica (MAPS) to yield 10 IM active fractions. All fractions and extracts then analyzed by Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry to reveal their molecular-level composition.
