Dataset for: Photochemical Oxidation of Oil Reduced the Effectiveness of Aerial Dispersants Applied in Response to the Deepwater Horizon Spill

This dataset reports the results of experiments to assess the effect of photochemical weathering on dispersant effectiveness. Macondo well oil was artificially weathered in the lab for use in dark-control and light-exposed treatments. Light-exposed treatments were exposed in a solar simulator for up to 24 hours. This dataset reports natural and chemical dispersion, carbonyl stretching intensity, dispersant efficacy, density, dynamic viscosity, and adhesion.
