Повний текст джерелаCoastal areas concentrate strong societal, economic and environmental issues. Monitoring and understanding the evolution of sea level in these zones is a key question, specially in the context of global climate change. To better understand the complex coastal dynamics, one needs to link and compare in-situ measurements (especially tide gauge ones) with global observations from altimetry satellites. Thanks to the development of GNSS technologies, it is now possible to design instruments that can map sea level, filling the gap between coastal observations and the satellite pass. This thesis presents an exhaustive study of two of these innovative systems: the CalNaGeo GNSStowed carpet and the Cyclopée system, mounted on the PAMELi autonomous surface vehicle. Through a series of tests, these two instruments have demonstrated their ability to measure sea level with centimetre accuracy. These new in-situ observations offer many perspectives for understanding and assessing the quality of altimetry data approaching the coast. We have analysed the raw altimetry observations and the correction parameters used to derive the water level in two coastal areas: the Pertuis Charentais and the Noumea Lagoon. In Noumea, in-situ data acquired during the GEOCEAN-NC campaign and those from coastal tide gauges were used to reconstruct along time series of sea level at the crossover point of three satellite tracks. By comparing in-situ and satellite data using methods developed at dedicated calibration/validation sites, we were able to reanalyse about twenty years of altimeter observations and re-address the question of relative and absolute sea level in this region

Повний текст джерелаThe rapid evolution of Charente's seashore is directly linked to numerous morphodynamic agents. Those marine factors stimulate each other and determine a very complex coastal landscape. This morphology includes cliffs marking by a permenent evolution. They are followed by very wide and heterogenous reef plate covered by depressions like bays, some of them being occupied by sand. Nevertheless, this dynalic tends to control the global evolution of Charente's seashore. Sandy coasts show many sand bars, whose aspects change very rapidly running along them, one can see, shore dunes more or less fixes by vegetation. The orientation and the origin of Charente's seashore are directly or indirectly linked to a favourable geological context (relative weakness of the rocks of the region), specially in cretaceous and jurassic periods. In the other hand, structural history shows that important accidents affected this region. At last, recent landforms of the coastal region of charente keeps after all the influences of last quaternary climatic changes

Повний текст джерелаThe purpose of this thesis is the study and the analysis of social and economic mutations for breeders of oysters. In the introduction, our hypothesis is that biological and economic constraints directly influence the family relations. These family relations turn into social production relations by the concept of the social and sexual partition of work. These relations move and influence the breeders of oysters when they can be neither checked nor quantified. In the second part, we shall see the social relations of producers : men and women place in production, the domination and the oyster-representations system, the exchange disposition and the distribution of the social produce. The third part treats of social and economic mutations in the oyster-society. The conclusion resumes the main points of the different parts and teaches us that, in the reproduction system of production way, imagination and dynamism in the oyster society play a leading role in the relations between biological constraints and economic constraints

Повний текст джерелаThe descriptive and analytical study of the diffent ways in which people have approached sea-bathing in la rochelle (charente-inferieure), in the 19th and 20th centuries, reveals an evolution in sea-bathing uses three succesive and distinct periods become evident beetween june 1870 and june 1936. The illusion of the hygienic effects of sea-bathing which brought about the apogy of essentially hygienic and therapeutic uses of maritimes bathing was followed by the abandonment of such usages, and, from 1890 to the first world war was replaced by apase of introduction of sea-bathing as a mass leisure activity during which the practice of swimming in the sea developed as a sport. The third period, between the two world wars was marked by a distinctive rise in the development of seaside leisure activities, notably as sport. This division into periods which is founded on the observation and description of various practice is confirmed by the research of patterns which can be conducted through the subsequent analysis of these practices. Three patterns thus make it possible to appreciate the ensemble of se-bathing usages : an hygienic pattern, a sport pattern and a play pattern. These come together, overlap and appear as a basic of the ensemble of the identified uses of sea-bathing in particular, they make it possible to understand their evolution and transformations. In short, if swimming appears as a permanent feature in la rochelle, as a distinctive use of sea-bathing and the one which representing the path of excellence, leisure sea-bathing, in various forms, nonetheless remains the most frequent usage

Повний текст джерелаThe effects of PAHs, considered among the most toxic by the United States Environmental Protection Agency, were tested in vitro and in vivo on two commercial species of the Pertuis-Charentais (Charente-Maritime, France): sea bass, Dicentrarchus labrax, and the Pacific oyster, Crassostrea gigas. This study was carried out as part of the European project EROCIPS with the aim of finding new immunological biomarkers caused by occasional pollution by hydrocarbons. During in vitro experimentation, pollutants and immunological biomarkers were choosen. Thereafter, the in vitro exposures to the soluble fraction of Erika’s heavy fuel oil and its fluxant, light cycle oil, began. These exposures enable the validation of the experimental system used, with, in particular, the measurement of bioaccumulated PAHs and metabolites and of choice of the immune biomarkers. The phenoloxidase activity of molluscs and the haemolytic activity of the alternative complement pathway of fish were proposed, for the first time, as suitable biomarkers for the evaluation of pollutant risks in field conditions
