Cet article porte sur la traduction intersémiotique des iconographies religieuses (Madeleine en extase et Madeleine pénitente) de la peinture en photographie. Il met l’accent sur le genre de la nature morte, lequel implique un rapport du texte visuel avec la sensorialité de l’observateur – qui devient « consommateur » de l’image. Cette recherche vise à analyser l’intertextualité, c’est-à-dire la convocation de valeurs d’un texte à l’autre (polémiques et iréniques), mais aussi le rapport entre statut religieux et statut artistique de l’image.

New results confirm earlier findings on the importance of tiemannite acumulation on speciation and inter-tissue relationships. It is hardly surprising that, as opposed to what was concluded earlier, major inter-regional differences in Hg accumulation can be demonstrated when comparing several populations of harbour porpoise on an age corrected basis. Important inter-species differences, probably depending on prey choice, are found, even after correction for "relative age". Regional differences are more important than the inter-species variability, at least within both classically described sub-orders of cetaceans. Based on actual estimates of MeHg exposure and tissue concentrations of Hg and MeHg in harbour porpoise from the Southern North Sea, Hg detoxification through precipitation of tiemannite is evaluated to neutralise on average 12% of the overall MeHg intake at age 7. Based on the idea of a 3 fold excess in toxicity of mercury over selenium and a 5 to 15 molar concentration excess of selenium over Hg in fish, Hg seems to play the major part in the mutual detoxification. The formation of tiemannite was previously described as resulting from a two-step accumulation mechanism appearing at a threshold level of Hg 100 g/g fw in liver. The reaching of an equimolar Hg to Se ratio can, however, be fully explained by the gradual increase of tiemannite levels in liver only. The new view is that molar Hg to Se hepatic ratios go towards equimolarity along with the slow nature of the tiemannite detoxification process, with tiemannite gradually taking the upper hand over MeHg, IHg2+ and a surplus of "free" selenium with the increase of the total Hg load.

The relationship between trophic position through delta(13)C and delta(15)N and trace metal concentrations (Zn, Cd, Cu and Hg) was investigated in the tissues of six marine mammal species from the Northeast Atlantic: striped dolphin Stenella coeruleoalba, common dolphin, Delphinus delphis. Atlantic white-sided dolphin Lagenorhynchus acutus, harbour porpoise Phocoena phocoena, white beaked-dolphin Lagenorhynchus albirostris, grey seal Halichoerus grypus stranded on French Channel and Irish coasts. White-beaked dolphins, harbour porpoises, white-sided dolphins, common and striped dolphins display the same relative and decreasing trophic position, as measured by delta(15)N values, along both the Irish and French channel coasts, reflecting conservative trophic habits between these two places. Hepatic and renal Cd concentrations were significantly correlated to muscle delta(13)C and delta(15)N values while Hg, Zn and Cu did not. These results suggest that Cd accumulation is partly linked to the diet while other factors Such as age or body condition might explain Hg, Zn or Cu variability in marine mammals. Combined stable isotope and trace metal analyses appear to be useful tools for the study of marine mammal ecology. (C) 2003 Elsevier Science Ltd. All rights reserved. [less ▲]

The fertile waters of the North Sea represent one major life site for at least three different marine mammal species: the harbour porpoise, Phocoena phocoena , the harbour seal, Phoca vitulina, and the white-beaked dolphin, Lagenorhynchus albirostris. More occasionally, oceanic species such as the white-sided dolphin Lagenorhynchus acutus, the sperm whale Physeter macrocephalus or the fin whale Balaenoptera physalus can be sighted or found stranded. Very few data dealing with marine mammal diet in the North Sea are available. In order to contribute to the feeding ecology of these North Sea marine mammals, Cd as well as 15N and 13C measurements have been performed in their tissues. Sperm whales and white-sided dolphins display high renal Cd levels (258 µg.g-1 and 88 µg.g-1 dry weight respectively). Mean Cd concentrations measured in harbour porpoise, harbour seal, white beaked dolphin and fin whale kidneys remain low (mean: 5, 0.9, 0.5 and 4 µg.g-1 respectively). However, some adult porpoises display renal Cd concentrations higher than 10 µg.g-1. Mean 13C measured in the muscles of sperm whales, fin whales and white-sided dolphins are more negative compared to harbour porpoise, harbour seal or white-beaked dolphin mean value. Cd contaminated porpoises display significant lower muscle 13C than other porpoises. Both low d13C and high Cd levels suggest a greater reliance of white-sided dolphins, sperm whales on oceanic cephalopods. It appears that some harbour porpoises can also feed on oceanic squids suggesting dynamic interactions between the North Sea and the North Atlantic porpoise populations. [less ▲]

The relationship between trace metal levels, trophic position and health status has been investigated in North Sea marine mammals. Stable isotope ratio (15N and 13C, mass spectrometry) and trace metal analyses (Cd, Pb, Cu, Zn, Se, Hg, I.C.P Spectrometry and flameless atomic absorption) have been performed in tissues of 52 harbour porpoises Phocoena phocoena, 27 harbour seals Phoca vitulina, 9 white-beaked dolphins Lagenorhynchus albirostris, 6 grey seals Halichoerus grypus, 1 hooded seal Cystophora cristata, 2 white-sided dolphin Lagenorhynchus acutus, 7 sperm whales Physeter macrocephalus and 4 fin whales Balaenoptera physalus, found stranded on the Northern French, Belgian and Southern Dutch coasts. The lowest 15N value has been measured in fin whales, and the highest in white-beaked dolphins, grey and common seals, suggesting a higher trophic position. Sperm whales, white-sided dolphins and hooded seal have strongly negative 13C values and high renal cadmium levels (258, 88 and 62 µg Cd .g-1dw, respectively) indicating that they might feed, at least in part, on oceanic cephalopods. High Hg liver concentrations can be encountered in older animals and reflect a cumulative storage of detoxified HgSe over the whole life span rather than a bioamplification process. Zn, Cu and Hg concentrations were higher in harbour porpoises from the Southern North Sea compared to other areas. Some individuals were severely emaciated as shown by their muscle atrophy and reduced blubber thickness. Hepatic Zn and Se concentrations were significantly higher in emaciated juvenile porpoises than in normal animals suggesting a severe disturbance of the metal homeostasis. To conclude, within the North Sea, trace metal levels in marine mammals display strong intra- and interspecies variations due to geographic origin, age, diet, trophic position but also by nutritional status of the individuals, raising the question of the suitability of marine mammals as valuable bioindicators of trace metal pollution.

The harbour porpoise Phocoena phocoena, grey seal Halichoerus grypus, harbour seal Phoca vitulina and white-beaked dolphin Lagenorhynchus albirostris are regularly found stranded along southern North Sea coasts. Occasionally, offshore species such as the fin whale Balaenoptera physalus, the white-sided dolphin L. acutus and the sperm whale Physeter macrocephalus are also found stranded. In order to trace their diet, we measured delta(13)C and delta(15)N in their muscles as well as in 49 invertebrate and fish species collected from the southern North Sea. The delta(15)N data indicate that the harbour seal, grey seal and white-beaked dolphin occupy the highest trophic position, along with ichtyophageous fishes such as the cod Gadus morhua (mean muscle values of 18.7, 17.9, 18.8 and 19.2parts per thousand respectively). The harbour porpoise occupies a slightly lower trophic position (mean delta(15)N value of 16.2parts per thousand), reflecting a higher amount of zooplanktivorous fishes in its diet (mean delta(15)N of 14.7parts per thousand); 2 suckling harbour porpoises displayed a significant delta(15)N enrichment of 2.2parts per thousand compared to adult females. Adult females are delta(15)N-enriched compared to adult male harbour porpoises. Fin whales, sperm whales and white-sided dolphins are C-13-depleted compared to southern North Sea particulate organic matter and species, suggesting that despite regular sightings, they do not feed within the southern North Sea area.

The harbour porpoise Phocoena phocoena, the harbour seal Phoca vitulina and the white-beaked dolphin Lagenorhynchus albirostris are commonly found stranded on the Belgian and Dutch coasts. More occasionally, oceanic species such as the white-sided dolphin Lagenorhynchus acutus, the sperm whale Physeter macrocephalus or the fin whale Balaenoptera physalus are also found stranded. For the last 10 years, trace analyses (Cd, Pb, Cu, Zn, Se, Hg) have been performed in their organs as well as complementary stable isotope ratio determinations (d15N and d13C) in order to trace their respective metal level and trophic position. Sperm whales, fin whales and white-sided dolphins display strong differences in their d13C and d15N values compared to harbour porpoises, harbour seals or white-beaked dolphins. The isotopic data from white-sided dolphins, sperm whales and fin whales suggest that they do not feed mainly within this area. On the contrary, porpoises, seals and white-beaked dolphins display close isotopic data reflecting a similar nutrition within the North Sea. However significant differences appear between these species: harbour porpoises display a significantly lower d15N (mean: 16.4 0/00 against 18.70/00 and 18.8 0/00 respectively) and d3C (mean-17 0/00 against –16 0/00 and –15.70/00 respectively) than harbour seals and white-beaked dolphins reflecting a lower trophic position of the porpoises.Moreover, Harbour porpoise isotopic compositions seem to have changed over the last five years, which could reflect a switch in their diet. In marine mammals, heavy metals are mainly absorbed through the diet and so potential relations between stable isotopes and heavy metals have been investigated. For example, it is suggested that harbour porpoises occasionally feed on cadmium contaminated preys as squids and that harbour seals and white-beaked dolphins are more restrictive on fish. [less ▲]

Related to the Gulf of Corinth rifting, five earthquakes of magnitude greater than 5.8 occurred in the last 35 years. Consequently, the question of earthquake (EQ) hazard is particularly relevant. Onland, paleoseismological data are scarce and offshore data were absent before the present study. We investigated recent sediments bounding three well-defined major seismogenic faults. We retrieved 12 gravity cores from 50 to 85 cm long in three distinct sites: the southern shelf (40 to 50 m deep), a 180 m deep sub-basin, and a transect from the southern coast to the center of the gulf. We performed grain size analysis, magnetic susceptibility, loss on ignition and geochemical (X-Ray Fluorescence) measurements on cores from each site. We sought to identify layers potentially attributed to EQ-related processes like liquefaction and tsunamis for the sites on the shelves or mass transport and turbidity currents for the basins. Chronology is based on 137Cs (Atmospheric Nuclear Experiments) and 210Pb decay. Considering sedimentation rates estimates in these areas, the longer cores record about 500 years of sedimentary archives. On the southern shelf, 3 coarser layers have been identified at identical depth in 3 cores. 210Pb decay show erosion just under the first event that we attributed to the 1995 tsunami (backwash flow deposit). In the 180m deep sub-basin, among 3 clear grain-size peaks, two have been attributed to the 1817 Aegion EQ and the 1660 Galaxidi EQ. In last site, 10 “events” (grain-size and Zr/Rb peaks) have been identified in the deepest part of the transect 4 on the shelf. Their analysis is in progress, as well as paleomagnetic measurements.

“During the course of the 20th century, the planet became and is now chemically different from any previous time”. (1) Organic and inorganic chemicals occur in greater abundance because of human activity and end up in the ocean. As more humans inhabit coastal regions, question arises about the health of our oceans. Marine vertebrates such as marine fish, turtles, birds and mammals are used to get early warning about negative trends and impact linked to anthropogenic activities. Such organisms are qualified as sentinel species (2). In turn, sentinels will permit us to better characterize and potentially manage negative impacts on human and animal health associated with our oceans. Marine predators including marine mammals and birds can present elevated concentrations of these organic and inorganic chemicals in their tissues, due to their high position in the trophic chain, their life span, and their fat store in which lipophilic chemicals accumulate. Humans and marine predators share common routes of exposures such as (1) the maternal transfer through placenta and milk and (2) trophic transfer through ingestion of marine fish and shellfish. Furthermore, some human population rely on marine mammal consumption for subsistence. Marine predators offer a snapshot of ocean health that could potentially impact human health. In the hope that this paper will stimulate the research much needed for assessing ocean health in the context of a rapidly changing environment, we provide here a review of (i) levels and trends of contaminants and relationships with biotic and abiotic factors, (ii) toxicological effects and (iii) spatial and geographical trends in tissues of marine predators. We conclude this communication by presenting several necessary perspectives such a more thorough follow of organic and inorganic pollutants in the marine environment including the use of isotopic tracers to assess the local versus global aspects of marine pollution.
