Development of oil hydrocarbon fingerprinting and identification techniques
Zhendi Wang,Merv Fingas +1 more
TL;DR: The fingerprinting and data interpretation techniques discussed include oil spill identification protocol, tiered analytical approach, generic features and chemical composition of oils, effects of weathering on hydrocarbon fingerprinting, recognition of distribution patterns of petroleum hydrocarbons, and application of other analytical techniques.
Journal Article
Petroleum Biodegradation in Marine Environments
TL;DR: Research on the fate of petroleum in a marine environment is important to evaluate the environmental threat of oil spills, and to develop biotechnology to cope with them.

Characterization of bacterial strains able to grow on high molecular mass residues from crude oil processing.
Luis Yuste,Marı́a Eugenia Corbella,Marı́a Jesús Turiégano,Ulrich Karlson,Antonio Puyet,Fernando Rojo +5 more
TL;DR: Analysis of the metabolic profiles of the strains isolated showed that they could all metabolize long-chain-length alkanes efficiently, but not PAHs, and their ability to produce surfactants was studied.

TL;DR: An experimental laboratory device maintaining pristine collected mudflat sediments in microcosms closer to true environmental conditions – with tidal cycles and natural seawater – was used to simulate an oil spill under bioturbation conditions and revealed two distinct microbial communities characterized by different phylotypes associated to known hydrocarbonoclastic bacteria and dominated by Gammaproteobacteria and DeltaproteOBacteria.

Effectiveness of bioremediation for the Exxon Valdez oil spill
TL;DR: A new interpretative technique used following the 1989 Exxon Valdez spill in Alaska shows that fertilizer applications significantly increased rates of oil biodegradation.

17.alpha.(H)-21.beta.(H)-hopane as a conserved internal marker for estimating the biodegradation of crude oil.
Roger C. Prince,David L. Elmendorf,James R. Lute,Chang Samuel Hsu,Copper E. Haith,James D. Senius,Gary J. Dechert,Gregory S. Douglas,Eric L. Butler +8 more
TL;DR: It is found that 17[alpha](H),21[beta](H)-hopane is neither generated nor biodegraded during the biodegradation of crude oil fractions on time scales relevant to estimating the cleansing of oil spills, and so it has the appropriate characteristics to serve as an internal standard for studying the biodesgradation of oil in the environment.

Role of hydrothermal precipitates in the geochemical cycling of vanadium
John H. Trefry,Simone Metz +1 more
TL;DR: The authors showed that scavenging by vent-derived iron oxides helps to control the concentration and cycling of vanadium in the ocean, and estimated that 10% to 60% of the riverine vanadium is removed from sea water by this mechanism and that such a process is also important for other elements.

Heat-flow variations correlated with buried basement topography on the Juan de Fuca Ridge flank
TL;DR: In this article, a detailed heat-flow and seismic-reflection survey over sediment-covered 3-Myr-old sea floor on the eastern flank of the Juan de Fuca Ridge was conducted.

Enhanced biodegradation of a light crude oil in sandy beaches
Kenneth Lee,Eric M. Levy +1 more
TL;DR: In this article, the authors conducted field trials over a 204 day period in the intertidal zone of a sandy beach in Atlantic Canada demonstrating an acute toxic response by natural microflora to the unweathered condensate, and bacterial growth in the oiled sediments did not increase until the concentration of toxic low molecular weight aromatic compounds had been reduced by evaporation and/or dissolution.
