Abstract:

This data set includes concentrations of chemical dispersant components measured in seawater collected following the Deepwater Horizon blowout. Components measured include the surfactants DOSS, Tween 80, Tween 85, and Span 80. Samples were collected between May 25 and June 6, 2010. The results describing the analytical method to detect surfactants presented in the associated paper (Place, B. J., Perkins, M. J., Sinclair, E., Barsamian, A. L., Blakemore, P. R., and Field, J. A. (2014). Trace analysis of surfactants in Corexit oil dispersant formulations and seawater. Deep Sea Research Part II: Topical Studies in Oceanography. doi:10.1016/j.dsr2.2014.01.015) are presented in dataset R1.x132.138:0001.

Purpose:

This data set was developed as part of a method demonstration for the analysis of the Corexit surfactants (EHSS, DOSS, Tween 80, Tween 85, and Span 80) in seawater.

Data Parameters and Units:

Sample Station, Distance from Wellhead (m), Depth (m), Concentration of surfactants (DOSS ng/L, α-/β-EHSS ng/L, Span 80 ng/L, Tween 80 ng/L, Tween 85 ng/L), RT (retention time), Area, IS area, signal to noise ratio (S/N). Sample stations latitude (decimal degrees) longitude (decimal degrees) and date of collection (MM/DD/YYYY): WS58 28.74 -88.38 06/01/2010; WS6 28.727 -88.423 06/04/2010; WS76 28.727 -88.378 06/05/2010; WS78 28.77 -88.52 06/05/2010; WS79 28.851 -88.489 06/06/2010; WS16 28.698 -88.556 06/06/2010

Methods:
