Analyse harmonique des séries chronologiques des niveaux d’eau et des courants au niveau de RasTaguermess et à el kantara dans le golfe de Gabès OceanDocs
Atoui., A.; Brahim, M.; Sammari, Ch..
Dans le cadre d’un programme national concernant l’étude de la circulation des eaux dans le littoral tunisien nous avons installé des courantomètres et des houlographes marégraphes dans le golfe de Gabès et notamment à l’Est de Djerba, en face de Ras-Taguermess et au niveau d’El Kantara. L’analyse harmonique des séries temporelles de niveau d’eau au niveau de Ras Taguermess et El-Kantara montre la dominance des composantes de la marée semi-diurne avec prédominance de la composante semi-diurne (M2) de période 12 h 25 mn. L’analyse en composantes principales où en fonction orthogonale empirique (EOF) des courants de la marée montre qu’au niveau d’El- Kantara la vitesse des courants est de 45 cm.s-1 et que sa direction est de 29° par rapport à l’Est ;...

Aspects temporels de l' impact de rejets radioactifs effectues en mer, sur les eaux d' une station littorale de la Manche ArchiMer
Fraizier, Albert; Guegueniat, Pierre; Salomon, Jean-claude.
Time-dependent impact of seaward radioactive discharges on waters of one coastal station of the English Channel. The disposai at sea of liquid waste from the nuclear fuel reprocessing plant at La Hague (CEA/Cogema) causes modifications to the radioactivity of marine waters in both space and time. Fluctuations in this radioactivity are controlled by many different parameters; to study these parameters, samples were taken, in particular, from a coastal site situated 5 km from the outlet pipe. The overall impact of these releases on the radioactivity of sea-water depends on various factors, including the amount and frequency of discharges, the hydrodynamic regime of water masses in the region and local meteorological conditions. In order to assess this...

Atmospheric Corrections and Multi-Conditional Algorithm for Multi-Sensor Remote Sensing of Suspended Particulate Matter in Low-to-High Turbidity Levels Coastal Waters ArchiMer
Novoa, Stefani; Doxaran, David; Ody, Anouck; Vanhellemont, Quinten; Lafon, Virginie; Lubac, Bertrand; Gernez, Pierre.
The accurate measurement of suspended particulate matter (SPM) concentrations in coastal waters is of crucial importance for ecosystem studies, sediment transport monitoring, and assessment of anthropogenic impacts in the coastal ocean. Ocean color remote sensing is an efficient tool to monitor SPM spatio-temporal variability in coastal waters. However, near-shore satellite images are complex to correct for atmospheric effects due to the proximity of land and to the high level of reflectance caused by high SPM concentrations in the visible and near-infrared spectral regions. The water reflectance signal ((w)) tends to saturate at short visible wavelengths when the SPM concentration increases. Using a comprehensive dataset of high-resolution satellite...

Balneola vulgaris gen. nov., sp nov., a member of the phylum Bacteroidetes from the north-western Mediterranean Sea ArchiMer
Urios, Laurent; Agogue, Hélène; Lesongeur, Francoise; Stackebrandt, Erko; Lebaron, Philippe.
A novel aerobic, Gram-negative bacterium, named 13IX/A01/164(T), was isolated from surface waters in the coastal north-western Mediterranean Sea. Cells were motile, straight rods, 2-5 mu m long and 0-2 mu m wide, and formed orange colonies on marine agar medium. The G+C content of the genomic DNA of strain 13IX/A01/164T was 42 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed the strain in the phylum Bacteroidetes within the family Crenotrichaceae. On the basis of 16S rRNA gene sequence comparison and physiological and biochemical characteristics, this isolate represents a novel species of a new genus, for which the name Balneola vulgaris gen. nov., sp. nov. is proposed. The type strain of Balneola vulgaris is 13IX/A01/164T (=DSM 17893T=CIP...

Bilan 1997 de la contamination des eaux côtières françaises par les composés organostanniques. ArchiMer
Michel, Pierre; Averty, Bernard.
Il y a quinze ans, la France prenait des mesures réglementaires pour restreindre l'usage des composés organostanniques dans les peintures antisalissures utilisées pour la protection des coques de bateaux. Il s'agissait alors d'une réaction d'urgence face au problème vital posé à l'ostréiculture française. La France était le premier pays à prendre de telles dispositions. Depuis, la réglementation a été confirmée à plusieurs reprises, en dernier lieu par le décret n°92-1074 du 2 octobre 1992. Quinze ans plus tard, où en sommes nous ? La campagne de mesure des composés organostanniques dans l'eau de mer, conduite par l'IFREMER de juillet à septembre 1997 a permis de faire le point de la situation. La contamination des côtes françaises reste préoccupante. Pour...

Cu, Pb AND Zn DISTRIBUTION IN NEARSHORE WATERS IN SAN JORGE BAY, NORTHERN CHILE Gayana
Salamanca,Marco A.; Camaño,Andrés; Jara,Bibiana; Rodríguez,Tatiana.
An extensive spatial survey metal content to study the spatial distribution of Cu, Pb and Zn concentration in nearshore waters of San Jorge Bay, along the coast of Antofagasta City, Chile was carried out located near the Atacama desert, which represent the largest populated urban settlement in northern Chile (~ 260,000 inhabitants). The coastal zone of this area is under an intensive use as discharge location of pollutants of different sources. Dissolved Cu varies between 0.97 to 1.65 mug l-1, in the southern part of the study area and in front of an industrial discharge, respectively. The dissolved Pb shows a narrow concentration range (0.019 to 0.029 mug l-1) and Zn content varies between 1.7 mug l-1 in the northern part of the study area to 2.0 mug l-1,...

Determination du profil des flores bacteriennes des zones littorales. Application a l'evaluation de l'impact des rejets ArchiMer
Bunetel, L; Segui, A; Guerin, J; Lerman, I; Cormier, M.
The principle of this method is to evaluate, by counts exercised upon selective media, the relative importance of the different bacteria families in the flora of the coastal waters. It is important to separate the contaminant species and the commensal species in the marine environment. Ten culture media distributed into four categories (selective, non selective, saline and non saline) were examined by numeration. Counts were transferred on a diagram allowing to plot down a profile of bacterial flora of water sampled from a given geographical area. The profiles are arranged by a classification method. The sampling points with similar or adjoining profiles were assembled and marked on the chart. In this way, the authors obtained areas representing the impact...

Development of a Semi-Analytical Algorithm for the Retrieval of Suspended Particulate Matter from Remote Sensing over Clear to Very Turbid Waters ArchiMer
Han, Bing; Loisel, Hubert; Vantrepotte, Vincent; Meriaux, Xavier; Bryere, Philippe; Ouillon, Sylvain; Dessailly, David; Xing, Qianguo; Zhu, Jianhua.
Remote sensing of suspended particulate matter, SPM, from space has long been used to assess its spatio-temporal variability in various coastal areas. The associated algorithms were generally site specific or developed over a relatively narrow range of concentration, which make them inappropriate for global applications (or at least over broad SPM range). In the frame of the GlobCoast project, a large in situ data set of SPM and remote sensing reflectance, R-rs(lambda), has been built gathering together measurements from various coastal areas around Europe, French Guiana, North Canada, Vietnam, and China. This data set covers various contrasting coastal environments diversely affected by different biogeochemical and physical processes such as sediment...

The state of pollution in the Lagos lagoon was examined by a field survey of twenty-six sites (stations) in the dry and wet season in 1985. Some selected sites were further re-examined in the same period in 1986. The sediment trace metals and total hydrocarbons were analysed. The relationship between non residual and residual trace elements was examined. For both years of study, total trace metal levels (mg/kg) fell in the ranges: Cu,1.9 – 132.4, Cr, 2.9 – 167; 7.8 – 830. 6; Ph, 1.6 – 483.1 and Cd, 0.04 – 15.5. Total hydrocarbon concentrations in 1985 ranged from 0.25 to 2766.27 mg/g with high concentrations in muddy and sandy sediments. The results show marked variations and non – uniform distribution from one season to another. With few exceptions,...
