Abstract:

Surface seawater collected from the Aransas Channel, Port Aransas, Texas (27°50'17.4"N 97°03'00.9"W) on July 15, 2013, was incubated with crude oil (surrogate Macondo oil) at initial concentrations of 0, 50, 10, 200, 400, and 800 ppm (0 ppm was not analyzed). The samples were incubated at room temperature for 50 d. Petroleum hydrocarbons were analyzed at 0, 5, 12, 28, and 50 d. This dataset represents the hydrocarbon (alkane) concentrations for different oil concentrations and various time points.

Purpose:

To determine the change of hydrocarbon concentrations during the degradation of different initial oil concentrations.

Data Parameters and Units:

Alkane (mg/L). Oil concentrations: 50 ppm, 100 ppm, 200 ppm, 400 ppm, 800 ppm (0 ppm was not analyzed). Sampling time: 0 d, 5 d, 12 d, 28 d, 50 d.

Methods:

The oil was extracted by dichloromethane. Clean up was done by silica gel and anhydrous sodium sulfate . Analysis was performed by gas chromatography- flame ionization detector.
