Fig. 15.4 (a) Double bond equivalent (DBE) and (b) carbon number distributions of the molecular
species detected in a sediment core from the northern GoM, which are related to characteristic
microbial biomarkers (e.g., Archaea, phytoplankton). Distributions of these biomarkers are useful
proxies of “normal,” background microbiome dynamics, but also of the perturbations related to oil
spills, such as the MOSFFA (Marine Oil Snow Sedimentation and Flocculent Accumulation)
event. The average depth of the sediment layers is from 3 mm (S3) to 112 mm (S112). (Reprinted
