Oil spill microcosms experiments were carried out to evaluate the effect of bioemulsificant exopolysaccharide (EPS2003) on quick stimulation of hydrocarbonoclastic bacteria. Early hours of oil spill, were stimulated using an experimental seawater microcosm, supplemented with crude oil and EPS2003 (SW+OIL+EPS2003); this system was monitored for 2 days and compared to control microcosm (only oil-polluted seawater, SW+OIL). Determination of bacterial abundance, heterotrophic cultivable and hydrocarbon-degrading bacteria were carried out. Community composition of marine bacterioplankton was determined by 16S rRNA gene clone libraries. Data obtained indicated that bioemulsificant addition stimulated an increase of total bacterial abundance and, in particular,... |

I used the 2010 Deepwater Horizon oil spill to examine how crowdsourcing is used as a new form of citizen science that provides real time assessments of health-related exposures. Assessing risks of an oil spill, or disasters more generally, is a challenge complicated by the situated nature of knowledge-generation that results in differential perceptions and responses. These processes are critical in the case of the British Petroleum spill in the Gulf Coast since the identification of risks promises to have ramifications for multiple social actors, as well as the health status and long-term resilience of communities in the area. Qualitative interviews, ethnographic observations, and video data were collected with local social movement organizations,... |

The issue of whether adaptations to past disasters can impede adaptation to new disasters of a different type or intensity will be analyzed by examining the transition from frequent hurricanes to the Deepwater Horizon oil spill in coastal Louisiana. In particular, the effects of changed regulatory structures from the Stafford Act to the Oil Pollution Act of 1990 in response to the Deepwater Horizon oil spill are investigated. The article describes how the federal, state, and local governments adjust. In addition, it illustrates the shifting focus on the environment with the activation of the Oil Pollution Act and the Clean Water Act. It wraps up with a discussion of the uncertainty that is pervasive in the case of the oil spill derived from changed... |

The focus of the research is the significance of dependence for communities to survive and adapt in times of environmental disasters. It shifts the emphasis on self-reliant communities for survival and examines the types and effects of dependence and external linkages by analyzing the range of community responses that include initial responses, early social impact, compensation, and conflicts after the Hebei-Spirit oil spill in December 2007 in Korea. The findings reveal that dependence is necessary, and the effects of dependence can be both positive and negative depending on the relations between external entities and affected communities as well as the community capacity to absorb resources and information. |

After the Deepwater Horizon oil platform explosion, an estimated 172.2 million gallons of gas-saturated oil was discharged uncontrollably into the Gulf of Mexico, causing the largest deep-sea blowout in history. In an attempt to keep the oil submerged, massive quantities of the chemical dispersant Corexit (R) 9500 were deployed 1522 m deep at the gushing riser pipe of the Macondo prospect's wellhead. Understanding the effectiveness of this unprecedented subsea dispersant injection (SSDI) is critical because deepwater drilling is increasing worldwide. Here we use the comprehensive BP Gulf Science Data (GSD) to quantify petroleum dynamics throughout the 87-day long blowout. The spatio-temporal distribution of petroleum hydrocarbons revealed consistent higher... |

The droplet size distribution (DSD) formed by gas-saturated oil jets is one of the most important characteristics of the flow to understand and model the fate of uncontrolled deep-sea oil spills. The shape of the DSD, generally modeled as a theoretical lognormal, Rosin-Rammler or non-fundamental distribution function, defines the size and the mass volume range of the droplets. Yet, the fundamental DSD shape has received much less attention than the volume median size (d50) and range of the DSD during ten years of research following the Deepwater Horizon (DWH) blowout. To better understand the importance of the distribution function of the droplet size we compare the oil rising time, surface oil mass, and sedimented and beached masses for different DSDs... |

At first, the chronology of remote sensing flights organized by CNEXO, IFP and IGN is summarized. Secondly, examples of the most commonly observed phenomena along the coastline are presented. An interpretation of the various data collected is given for the area of Roscoff, taken as a model. This interpretation is extended to draw a serie of maps of sea and coastline pollution for several days between March 18 to May 26, 1978. The maps for the 18th and 21st of March are enclosed. |

The Aber Benoît, a small estuary on the North West coast of Brittany was polluted by oil from the Amoco Cadiz oil spill. Preliminary results from water and sediment samples taken in the estuary in May 1978, show that two months after the initial spill, high concentrations of hydrocarbures existed in the water and sediments of the estuary. The Aber Benoît shows a well developed salt wedge and upstream increasing suspended sediment concentrations. Oil was dispersed more or less evenly throughout the water column, in the entire length of the estuary. In the bottom sediments, oil had accumulated to depths of 30 cm. Sand bars appear to induce a trapping of oil in the estuary channel. |

Spaceborne synthetic aperture radar (SAR) is well adapted to detect ocean pollution independently from daily or weather conditions. In fact, oil slicks have a specific impact on ocean wave spectra. Initial wave spectra may be characterized by three kinds of waves, namely big, medium, and small, which correspond physically to gravity and gravity-capillary waves. The increase of viscosity, due to the presence of oil damps gravity-capillary waves. This induces not only a damping of the backscattering to the sensor but also a damping of the energy of the wave spectra. Thus, local segmentation of wave spectra may be achieved by the segmentation of a multiscale decomposition of the original SAR image. In this paper, a semisupervised oil-slick detection is... |

The wreckage of the tanker "AMOCO CADIZ" on the reefs of PORTSALL was the fourth oil spill in ten years on the coast of Brittany : it also is the largest known oil spill in the world. The patches at sea were driven eastward by westerly winds from March 17 to March 23. 140 Km of coast line was polluted. The oil spreaded more slowly towards the north west, south and north west where it spoiled some 375 Km of touristic sea coast and important fishing grounds. The coastline is six kilometers wide ; it includes islands and large reefs. The local tidal currents are very strong and reach more than three knots, during spring tides which may rise up to nine meters in a rough sea conditions. The turbulence of the water soon dispersed the slicks and mixed the oil... |

A 3-year survey was made of several biological markers in mussels (Mytilus edulis) exposed in situ to the oil that came ashore after the wreck of the "Erika" tanker on the Brittany (France) coast in December 1999. The mussel response was assessed using a set of 7 biomarkers, most of them related to the metabolism of organic contaminants. After a series of validation tests, data was evaluated for only 5 biomarkers: acety1cholinesterase (AChE), glutathione S-transferase (GST), catalase (CAT), malondialdehyde (MDA) and deoxyribonucleic acid (DNA) adducts. No significant reductions in GST or CAT levels were observed, levels of DNA adducts and MDA were high during the 6 months immediately following the accident and levels of AChE were significantly lower during... |

Human alteration of marine ecosystems is substantial and growing. Yet, no adequate methodology exists that provides reliable predictions of how environmental degradation will affect these ecosystems at a relevant level of biological organization. The primary objective of this study was to develop a methodology to evaluate a fish’s capacity to face a well-established environmental challenge, an exposure to chemically dispersed oil, and characterize the long-term consequences. Therefore, we applied high-throughput, non-lethal challenge tests to assess hypoxia tolerance, temperature susceptibility and maximal swimming speed as proxies for a fish’s functional integrity. These whole animal challenge tests were implemented before (1 month) and after (1 month)... |

Oil spills pose a threat to aquatic organisms. However, the physiological effects of crude oil on cardiac function and on thermal tolerance of juvenile fish are still poorly understood. Consequently, in this paper, we will present results of two separate experiments where we exposed juvenile rainbow trout and European sea bass to crude oil and made cardiac thermal tolerances and maximum heart rate (fHmax) measurements after 1 week (rainbow trout) and 6-month recovery (sea bass). In both species, the fHmax was lower in crude oil-exposed fish than in the control ones at temperatures below the optimum but this difference disappeared at higher temperatures. More importantly, the oil-exposed fish had significantly higher Arrhenius break point temperature for... |

Evaluating the ecological impact of an oil spill is a complex issue requiring coherently articulated examination of the sequence of interactions that link the cell, where contaminants exert their effects, to the ecosystem, where interactions with human activities arise. This sequence of interactions traverses the frontiers between scientific disciplines (chemistry, toxicology, physiology, and fisheries ecology). Using the common sole (Solea solea L.) as a model species for the coastal habitats polluted by the "Erika" oil spill, our research project attempted to define indices of functional integrity that characterised the consequences of fuel exposure at the different biological levels. The coupling of field observations with experimental laboratory work... |
