this paper presents results analyses of specific potential blowout scenarios for subsea oilpipelines between the coast of mainland of iran and khark island in the persian gulf. the analyses have been carried out with the sintef oil spill contingency and response (oscar) 3-dimensional model system.some hypothetical three-day blowout scenarios with light and heavy iranian oil have been investigat...

Halomonas species are recognized for producing exopolysaccharides (EPS) exhibiting amphiphilic properties that allow these macromolecules to interface with hydrophobic substrates, such as hydrocarbons. There remains a paucity of knowledge, however, on the potential of Halomonas EPS to influence the biodegradation of hydrocarbons. In this study, the well-characterized amphiphilic EPS produced by...

BACKGROUND Although public concern has focused on the environmental impact of the Deepwater Horizon oil spill, the public health impact on a broad range of coastal communities is minimally known. OBJECTIVE We sought to determine the acute level of distress (depression, anxiety), mechanisms of adjustment (coping, resilience), and perceived risk in a community indirectly impacted by the oil spi...

The Deepwater Horizon oil spill triggered a complex cascade of microbial responses that reshaped the dynamics of heterotrophic carbon degradation and the turnover of dissolved organic carbon (DOC) in oil contaminated waters. Our results from 21-day laboratory incubations in rotating glass bottles (roller bottles) demonstrate that microbial dynamics and carbon flux in oil-contaminated surface wa...

Trajectory and fate modeling of the oil released during Deepwater Horizon blowout was performed for April to September 2010 using a variety input data sets, including combinations seven hydrodynamic four wind models, determine inputs leading best agreement with observations evaluate their reliability quantifying exposure marine resources floating subsurface oil.

The risk of oil spills is a major environmental issue in the siting of proposed coastal refineries, oil terminals, deepwater ports, and in the leasing of offshore lands for oil exploration and development. As with any kind of risk, oil spill risk assessment is inherently judgmental and no analytic method can eliminate the need for judgment. This paper compares representative examples of oil spi...

The Deepwater Horizon semi-submersible Mobile Offshore Drilling Unit (MODU), leased to BP (previously British Petroleum, now simply “BP”, with the previously-used promotional tagline of “beyond petroleum”) suffered an explosive “blowout” on April 20, 2010 which resulted in what is now the largest offshore oil spill in United States (U.S.) history, and currently estimated to be at least the seco...

Oil spillage has been a major environmental problem in Nigeria for more than two decades. Between 1976 and 1996 Nigeria recorded a total of 4835 oil spill incidents, which resulted in a loss of 1.9 million barrels of oil into the environment. From 2006 to 2008 reported oil spill occurrences amounted to 1260, where 40,000 barrels of oil from Mobil platform off the Akwa Ibom coast were spilt, cau...
