Project Description

Crude oil could be dissolved, oxidized, evaporated, degraded (including microbial and photochemical degradation), and fractionated into hydrocarbon fractions in the marine environment, changing its original optical, chemical and isotopic signatures such as fluorescence excitation-emission characteristics and spectral slope as well as molecular size distribution. However, the quantitative changes in hydrocarbon speciation and thus the chemical and optical properties of seawater during the degradation of oil and dispersant are poorly understood, which makes interpretation of field data challenging.
