Abstract:

The file contains the percentage remaining for five different classes of saturated hydrocarbons (normal alkanes, cycloalkanes, methylalkanes, acyclic isoprenoids, and cyclic isoprenoids), for eight different samples collected on beaches in the impacted region 12-19 months after the beginning of the Deepwater Horizon disaster. These percentages remaining were quantified using the procedure described in Gros et al., "Resolving biodegradation patterns of persistent saturated hydrocarbons in weathered oil samples from the Deepwater Horizon disaster", Environ. Sci. Technol., 2014. The value of the saturate biodegradation index is also provided. These data were used to draw Figure 5 in the article cited above.

Purpose:

To study the extent of biodegradation in weathered oil residues from the Deepwater Horizon disaster.

Data Parameters and Units:

Percent remaining for normal alakanes, cycloalkanes, metylalkanes, acyclic isoprenoids, cyclic isoprenoids. Saturate biodegradation index calculated as I_s=F_n + F_b + F_i where F_n is the fraction of n-C_22-n-C_29 n-alkanes remaining in the weathered samples relative to original MW oil; F_b is the fraction remaining for alkylcyclopentanes+alkylcyclohexanes and methylalkanes in the n-C_22-n-C_29 elution window; and F_i is the fraction remaining for acyclic and cyclic isoprenoid compounds in this window.
