Abstract:

This dataset contains residual oil components extracted from sediment samples associated with larval collections from coastal Louisiana collected in between 2011-08-25 through 2011-09-28. Both alkanes and Polycyclic Aromatic Hydrocarbons (PAHs) content in sediments were analyzed with Gas Chromatography-Mass Spectrometry (GC-MS) using the SIM acquisition mode.

Data Parameters and Units:

The dataset reports oil residue analyses; A total of 43 PAHs, Napthalenes, Fluorenes, Dibenzothiophenes, Phenanthrenes, Anthracene, Fluoranthenes, Pyrenes, Napthobenzothiophenes, Benzo Anthracene, Chrysenes, Benzo Fluoranthenes, Benzo Pyrenes, and Perylenes; and a total of 28 Alkanes, nC-10 Decane, nC-11 Undecane, nC-12Dodecane, nC-13 Tridecane, nC-14 Tetradecane, nC-15 Pentadecane, nC-16 Hexadecane, Pristane, nC-18 Octadecane, Phytane, nC-19 Nonadecane, nC-20 Eicosane, nC-21 Heneicosane, nC-22 Docosane, nC-23 Tricosane, nC-24 Tetracosane, nC-25 Pentacosane, nC-26 Hexacosane, nC-27 Heptacosane, nC-28 Octacosane, nC-29 Nonacosane, nC-30 Triacontane, nC-31 Hentriacontane, nC-32 Dotriacontane, nC-33 Tritriacontane, nC-34 Tetratriacontane, and nC-35 Pentatricontane are recorded as parts per billion (ppb). Main parameters: Site (sample collection site), Date collected (Date of sample collection; MM/DD/YYYY), Latitude (decimal degrees), Longitude (decimal degrees), Alkanes and Polycyclic Aromatic Hydrocarbons (Parts per billion, ppb). Please note ND = Non-detect and MDL= Below method detection limit.

Methods:

Total Polycyclic Aromatic Hydrocarbon (PAH) content in sediments in East Louisiana where oil made landfall was measured using Gas Chromatography-Mass Spectrometry (GC-MS) using the SIM acquisition mode. This method targeted 28 alkanes and 18 parent aromatic hydrocarbons based on EPA SW-846 methods (2000). PAH measurements were conducted at the Department of Environmental Sciences by Scott Miles. A detailed description of the extraction and analysis of PAHs can be found in a previous publication of Scott Miles (Turner et al., 2014).
