Abstract The Deepwater Horizon oil spill constituted an ecosystem-level injury in the
northern Gulf of Mexico. Much oil spread at 1100–1300 m depth, contaminating and …

The lack of a conceptual understanding and unifying quantitative framework to guide
conduct and interpretation of laboratory oil toxicity tests, has led investigators to divergent …

The sea surface microlayer (SML) is the boundary interface between the atmosphere and
ocean, covering about 70% of the Earth's surface. With an operationally defined thickness …

Offshore waters have a high incidence of oil pollution, which poses an elevated risk of
ecological damage. The microbial community composition and metabolic mechanisms …

During toxicity testing, chemical analyses of oil and exposure media samples are needed to
allow comparison of results between different tests as well as to assist with identification of …

Chemical analysis of large populations of floating (n= 62) and stranded (n= 1174) Macondo
oils collected from the northern Gulf of Mexico sea surface and shorelines during or within …

Petroleum products in the environment can produce significant toxicity through
photochemically driven processes. Burning surface oil and photochemical degradation were …

For the first time, trapped ion mobility spectrometry (TIMS) in tandem with Fourier transform
ion cyclotron resonance mass spectrometry (FT-ICR MS) is applied to the analysis of the low …

Chemical analysis of sediment cores collected up to 8 km from the Macondo well in
2010/2011 demonstrates the extent of weathering of the Macondo oil deposited in deep-sea …

Photoproducts can be formed rapidly in the initial phase of a marine oil spill. However, their
toxicity is not well understood. In this study, oil was irradiated, chemically characterized, and …
