After the Cap: Risk Assessment, Citizen Science and Disaster Recovery Ecology and Society
McCormick, Sabrina; George Washington University; sabmc@gwu.edu.
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,...

Assessing chronic fish health: An application to a case of an acute exposure to chemically treated crude oil ArchiMer
Mauduit, Florian; Domenici, P.; Farrell, A. P.; Lacroix, C.; Le Floch, S.; Lemaire, P.; Nicolas-kopec, A.; Whittington, M.; Zambonino-infante, Jose-luis; Claireaux, Guy.
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)...

Biological effects of the "Erika" oil spill on the common mussel (Mytilus edulis) ArchiMer
Bocquene, Gilles; Chantereau, Sebastien; Clerendeau, Christelle; Beausir, Emilie; Menard, Dominique; Raffin, Bernard; Minier, Christophe; Burgeot, Thierry; Leszkowicz, Annie Pfohl; Narbonne, Jean-françois.
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...

Chemical and microbiological characterization of mangrove sediments after a large oil-spill in Guanabara Bay - RJ - Brazil BJM
Maciel-Souza,Maria do Carmo; Macrae,Andrew; Volpon,Antonia Garcia Torres; Ferreira,Patrícia Silva; Mendonça-Hagler,Leda Cristina.
Seventeen months after a 1,3 million L oil spill into Guanabara Bay, analyses of mangrove sediments showed that the three sites closest to the spill remain highly polluted (>10 µg-g-1 polyaromatic hydrocarbons). A fourth site was less polluted, from which most hydrocarbon degrading bacteria were isolated.

Community Adaptation to the Hebei-Spirit Oil Spill Ecology and Society
Cheong, So-Min; University of Kansas; somin@ku.edu.
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.

Effect of coastal processes on the distribution and persistence of oil spilled by the Amoco-Cadiz - Preliminary conclusions ArchiMer
D'Ozouville, Laurent; Gundlach, E.r.; Hayes, M.o..
The section of North Brittany contaminated by the "AMOCO-CADIZ" oil spill (17 March 1978) is a low-lying ria coastline dominated by dynamic processes favorable for the rapid dispersion of the oil. Aerial and ground surveys were made of the impacted area on 19 March - 2 April and 20 - 28 April 1978, to detail the distribution and persistence of oil along the shoreline. Oil deposition on the shoreline was primarily controlled by local geomorphology (e.g. rocky headlands, tombolos, crenulate bays, etc..) and wind-driven currents. Our results indicate that approximately 62.000 tons of oil was spread along 123 km of coastline and offshore rocks at the time of our first study. During the second study period, oil was distributed along 375 km of shoreline and...

Esquisse d'un bilan écologique provisoire de l'impact de la marée noire de l"Amoco-Cadiz" sur le littoral ArchiMer
Chasse, C..
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...

Etat de la pollution par les hydrocarbures dans l'Aber Benoit ArchiMer
Allen, G.; D'Ozouville, Laurent; L'Yavanc, Jacky.
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.

From frequent hurricanes to the Deepwater Horizon oil spill in coastal Louisiana: the impact of regulatory change Ecology and Society
Cheong, So-Min; University of Kansas, Department of Geography; somin@ku.edu.
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...

Impacts of oil spills on altimeter waveforms and radar backscatter cross-section ArchiMer
Cheng, Yongcun; Tournadre, Jean; Li, Xiaofeng; Xu, Qing; Chapron, Bertrand.
Ocean surface films can damp short capillary-gravity waves, reduce the surface mean square slope, and induce “sigma0 blooms” in satellite altimeter data. No study has ascertained the effect of such film on altimeter measurements due to lack of film data. The availability of Environmental Response Management Application (ERMA) oil cover, daily oil spill extent and thickness data acquired during the Deepwater Horizon (DWH) oil spill accident provides a unique opportunity to evaluate the impact of surface film on altimeter data. In this study, the Jason-1/2 passes nearest to the DWH platform are analyzed to understand the waveform distortion caused by the spill as well as the variation of σ0 as a function of oil thickness, wind speed and radar band. Jason-1/2...

Influence of crude oil exposure on cardiac function and thermal tolerance of juvenile rainbow trout and European sea bass ArchiMer
Anttila, Katja; Mauduit, Florian; Le Floch, Stephane; Claireaux, Guy; Nikinmaa, Mikko.
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...

Influence of oil exposure on the physiology and ecology of the common sole Solea solea: Experimental and field approaches ArchiMer
Claireaux, Guy; Desaunay, Yves; Akcha, Farida; Auperin, Benoît; Bocquene, Gilles; Budzinski, Hélène; Cravedi, Jean-pierre; Davoodi, Fariba; Galois, Robert; Gilliers, Camille; Goanvec, Christelle; Guerault, Daniel; Imbert, Nathalie; Mazeas, Olivier; Nonnotte, Guy; Nonnotte, Liliane; Prunet, Patrick; Sebert, Philippe; Vettier, Aurélie.
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...

Nickel and vanadium contamination of benthic invertebrates following the "Erika" wreck ArchiMer
Chiffoleau, Jean-francois; Chauvaud, Laurent; Amouroux, David; Barats, Aurélie; Dufour, Aurélie; Pecheyran, Christophe; Roux, Nathalie.
Levels of nickel and vanadium, trace metals found in high concentration in the oil spilled from the "Erika" tanker off Brittany (France) in December 1999 (41 +/- 1 and 87 +/- 3 mg kg(-1) respectively), have been monitored over a one-year period following this accidental event in several benthic invertebrates. Ni and V in mussels (Mytilus edulis) and oysters (Crassostrea gigas) soft tissues were analysed twice a month by graphite furnace atomic absorption spectrometry and a scallop (Pecten maximus) shell daily growth bands were sampled every three bands by laser ablation and analysed by ICP-MS for these two contaminants. Survey data for mollusc tissues were compared with reference data arising from the national monitoring database. Ni concentrations in...

Partially supervised oil-slick detection by SAR imagery using kernel expansion ArchiMer
Mercier, Grégoire; Ardhuin, Fanny.
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...

Quick stimulation of Alcanivorax sp. by bioemulsificant EPS2003 on microcosm oil spill simulation BJM
Cappello,Simone; Genovese,Maria; Denaro,Renata; Santisi,Santina; Volta,Anna; Bonsignore,Martina; Mancini,Giuseppe; Giuliano,Laura; Genovese,Lucrezia; Yakimov,Michail M..
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,...
