SAMPLE_DESCRIPTION:
Spectrum of beach sand saturated with weathered oil from the Deepwater Horizon spill measured on the beach on Grand Isle, Louisiana. Spectrum measured in the field on June 9, 2010. The reflectance spectrum has strong absorption features centered near 1.72 and 2.30 microns arising from C-H bonds in weathered oil.
This spectrum labeled "Oiled-sand, black" was published and described in:
