This dataset contains the lipid class composition of red snapper (Lutjanus campechanus) exposed to a chemically enhanced water-accommodated fraction (CEWAF) of south Louisiana crude oil and a pathogen, obtained using Iatroscan and fatty acid identification. The dataset includes details on experimental setup and conditions, CEWAF preparation, and loading concentrations for pathogen exposures.



Dataset contains laboratory measurements, no field sampling was involved.

Supplemental Information

The dataset contains 1 Excel file with multiple worksheets that detail the experimental setup and conditions (Test Conditions table, Sample Key, System Key), how CEWAF were made (CEWAF Preparation), loading concentrations for pathogen exposures (Vibrio Loads), and lipid class composition. The contents of all the worksheets are described below: Naming convention: Sample IDs are named as "CII-15-0000", where three letter laboratory project code (CII=CIMAGE-II)-two digit year (2015=15)-four digit integral assigned by laboratory beginning at 0000 for each new year (0000 through 9999). Please note: MML= Mote Marine Laboratory; MDL= Minimum Detectable Limit; SW = seawater; CEWAF = chemically enhanced water accommodated fraction of oil; R = Reservoir; T = Tank; C/B/C = CEWAF/ bacteria/ CEWAF; B = Bacteria; CEWAF/B/SW = chemically enhanced WAF/bacteria/seawater; CFU = colony-forming unit; ATTC = ATCC is the premier global biological materials resource and standards organization whose mission focuses on the acquisition, authentication, production, preservation, development, and distribution of standard reference microorganisms, cell lines, and other materials.

Lipid Composition: 1 uL of the sample analyzed with Iatroscan using PeakSimple 444 software. Fatty Acids: 1 uL of the sample analyzed with Agilent 7890A/5975C, Zebron Capillary column.|Iatroscan MK-6s, Agilent 7890A/5975C, Zebron Capillary column.||QA measures were included into per batch according to Environmental Laboratory for Forensics Quality Assurance Plan. If QA measurements were not met, samples were re-analyzed or data was qualified.|


Controlled oil exposure study to evaluate the effects of crude oil on lipid structure in whole body of fish.
