Estimation par spectrofluométrie des concentrations d'hydrocarbures dans l'eau de mer en Manche Occidentale à la suite du naufrage de l"AMOCO CADIZ" du 30 mars au 18 avril 1978
Provedor de dados: 5
Autores: Marchand, Michel.
The oil .pollution,resulting from the "AMOCO CADIZ" tanker spill on the Brittany coast of North Finistere-has affected a very large section of the western Channel, limited for the period covering March 30 to April 18 to the west by the 5°W meridian, to the east by the St-Brieuc Bay, to the north by the 49°20' parallel. The contents of hydrocarbons observed in sea water at different levels show that the whole of water column is contaminated by hy­drocarbons and indicate very probably the pollution of the sedimentary phase in the areas, hited by the drifting sheets.

Observations préliminaires recueillies dans l'exécution des programmes entrepris par la station biologique de Roscoff
Provedor de dados: 5
Autores: Bergerard, S.
We have tried to expose here the first observations on the basis of , previous knowledge and studies in progress when the wreck arrived, in particulary of benthic Populations Dynamics by the workers of the Biological Station. These results, still very fragmentary, allow never the less to definite the programs required for the second phase, essentially on the populations of fine deposits of the Morlaix and Lannion bays.

Dégradation bactérienne du pétrole brut dans des sédiments marins littoraux de la Bretagne nord
Provedor de dados: 5
Autores: Fusey, P.; Oudot, J.
The weathering of petroleum was monitored by high temperature high resolution gas-liquid chromatography in northern Brittany seashore sediments, either contaminated by the Amoco Cadiz oil or experimentally polluted. Most aliphatic and aromatic hydrocarbons were relatively rapidly degraded, but some compounds like isoprenoids (pristane and phytane), triterpanes and alkylated phenanthrenes and dibenzothiophenes appeared to be more recalci­trant. In high energy sites (Roscoff beach), cleaning of the sediments was achieved between 12 and 18 months, whereas the Abers muddy sediments contained after two years bacterially neosynthesised very long chain n-alkanes (&gt;n-C50). Interaction between physical leaching and biodegradation was responsible for sediments...

Effet du pétrole de l'"Amoco Cadiz" sur les oiseaux de mer. Bilan provisoire
Provedor de dados: 5
Autores: Monnat, J.y.
Immediatly following the AMOCO CADIZ oil spill, the S.E.P.N.B. carried out health centers for oiled birds from Finistère, and estimated the impact of the oil spill on seabirds. In the whole, 15 to 20 000 birds are dead because of the AMOCO CADIZ oil spill. 41 species have been oiled, among which 35 usually live in marine environment. The species most stressed belong to alcidae. The mortality rate (0,1 bird/ton of oil) seems to be, at. present day, the lowest rate never mentionned in the litterature.

Impact de la pollution aux hydrocarbures sur l'écophysiologie et la pathologie des bivalves d'intérêt commercial de la Côte Atlantique
Provedor de dados: 5
Autores: Martin, Jean-louis; Haure, Joel; Thebault, Anne; Goulletquer, Philippe.
The evaluation of the ecological and economical consequences of the hydrocarbon pollution of the Erika implies the setting up of monitorings, analysis and experiments in the short, medium and long term. Among the consequences to be evaluated, a great deal of attention has to be paid to the direct impact on the biology and production performances of the main shellfish species as about 30% of the national production (around 130,000 tons of oysters and 60,000 tons of mussels per year) is cultivated in the impacted area. The main difficulty in evaluating the effects of the contaminants on a distinct part of the ecosystem which is mostly dominated by a cultured population dwells in the different approaches to set up as well as the variability of the answers...

Traitement biologique de nappes d'hydrocarbures en mer et influence de facteurs abiotiques
Provedor de dados: 5
Autores: Tagger, S.; Bianchi, A.; Julliard, M.; Le Petit, J.; Roux, B.
The supply of hydrocarbons oxidizing marine bacteria to petroleum polluted sea water has not resulted in an increase in the hydrocarbons degradation potential of this water. All the allochtone species have disappeared from the dominant microflora seven days after the treatment while the autochtone bacteria show a capacity for adaptation to the petroleum products which needs about four days of petroleum-contact to appear. This confirms the advantage of a fast proliferation of these bacteria in oil slides which could be provoked by supply of immediately assimilable nitrogenous and phosphorised mineral compounds. The degradation potential of polluted water must be raised to its maximum as fast as possible after an oil spillage in order not to let the aromatic...

Amoco-Cadiz : Informations sur la contamination des espèces exploitées
Provedor de dados: 5
Autores: Michel, Pierre; Abarnou, Alain.
This report is a statement of the analytical results obtained in the control of the exploited species three months after the AMOCO CADIZ ran aground on the coast of Brittany. Different samples have been studied, among these : algae, crustaceans (Maïa squinado and Cancer pagurus). twenty species of fish, and molluscs (Ostrea edulis. Crassostrea gigas. Mytilus edulis) Algae have been heavily contaminated but are partically available for algi­nate industry. Molluscs are not presently edible within the whole polluted area. Fishes and crustaceans are less polluted.

Critères de pollution par hydrocarbures dans les sédiments marins. Étude appliquée à la pollution du "Bohlen"
Provedor de dados: 5
Autores: Marchand, Michel; Roucache, J.
In October 16, 1976, the tanker "Bohlen" was wrecked in the Mer d'Iroise, at about 35 miles of Brest, and lossed about 7 000 t of Boscan crude oil. The coast of Brittany was polluted by 3 000 t, and 4000 t were dispersed in the marine environment. In July 1977, 23 surface sediment samples were collected to look for the traces of oil spill in the sea bottom, 9 months after the shipwreck. Only one sediment was very iittle polluted by the Boscan crude oil. Elsewhere, two other kinds of oil pollution were observed in sorne sediment samples. Severa! quantitative and qualitative criteria were used to research sorne oil pollution in the marine sediments and to know the origin: hydrocarbon concentrations, ratios total organic extra ct 1 organic carbon,...

Impact de l'Erika sur la pathologie de bivalves d'intérêt commercial: résultats préliminaires
Provedor de dados: 5
Autores: Thebault, Anne; Robert, Maeva; Renault, Tristan; Dumais, M.; Goulletquer, Philippe.
Après le naufrage de l'Erika, la question s'est rapidement posée de l'impact des hydrocarbures sur la santé des coquillages, car la pollution concernait des zones de production conchylicoles. Le suivi zoosanitaire en place dans ces zones permettait d'avoir des données de référence avant impact. Il a été choisi différents sites exposés de référence, qui ont fait l'objet d'analyse en toxicologie et en pathologie. A la différence du cas de l'Arnoco Cadiz, l'effort n'a pas été mis uniquement sur les huîtres mais aussi sur d'autres espèces de coquillages, comme les moules et des fouisseurs, particulièrement exposés comme les coques et les palourdes. La mesure de l'exposition effectuée par la Direction de l'Environnement Littoral (MONERlKA) montre qu'une...

Evolution des hydrocarbures et activité bactérienne dans les sédiments côtiers méditerranéens
Provedor de dados: 5
Autores: Azoulay, E.; Dubreuil, J.; Colin, H.; Dou, H.; Mille, G; Giusti, G.
The evolution of the hydrocarbons in the marine sediments of the mediterranean coast was studied by two different but complementary methods. In the first part of this study we describe results obtained through a technique specially adapted to sediments. It leads to a relatively accurate and reproducible determination of the hydrocarbon concentrations in sediments collected at many sites of the mediterranean coast polluted or not by chroni­cal petroleum inpout (Brusc lagoon, zones of Embiez, Fos, Carry-le-Rouet, and Etang de Berre).  The hydrocarbon concentrations in the non-polluted sediments are always inferior to 300 mg/kg of dry sediment with important variations according to seasons (x 4 during winter). In the polluted sediments the hydrocarbon...

Origin of organic compounds in fluids from ultramafic-hosted hydrothermal vents of the Mid-Atlantic Ridge
Provedor de dados: 5
Autores: Konn, Cécile.
Natural gas, primarily methane (CH4), is produced in substantial amounts in ultramafic-hosted hydrothermal systems. These systems could also generate oil (heavier hydrocarbons) and the first building blocks of life (prebiotic molecules). In the presence of iron bearing minerals, serpentinisation reactions generate H2. Subsequently, CH4 could be synthesised by Fischer-Tropsch Type (FTT) reaction (4H2 + CO2 -&gt; CH4 + 2H2O) which is an abiotic process. This has lead to the idea of abiotic formation of larger organic molecules. Both thermodynamics and laboratory work support this idea, yet field data have been lacking. This study focuses on determining the organic content of fluids from ultramafic-hosted hydrothermal systems from the Mid-Atlantic Ridge (MAR)...
