SAMPLE_DESCRIPTION:
Weathered oil from the Deepwater Horizon spill coating marsh plants. The oil-coated plants were collected on July 10, 2010, in an amber glass jar and stored on ice until spectral measurements were made in the laboratory on July 11, 2010. The spectrum is an average of 9 measurements made of oil-coated Juncus roemerianus and Spartina alterniflora. The reflectance spectrum has absorption features centered near 1.72 and 2.30 microns arising from C-H bonds in weathered oil.
