Full textThe present day Aude valley’s coastal landscape is the result of unstable lagoonal and deltaic environments during the last millennia. The understanding of past environmental dynamics is a key issue of the local ar-chaeological research, because since the Neolithic period human beings have settled in this area. This work aims to identify and explain the fluvio-lagoonal landscape’s evolution in the Narbonne region during the Holocene by using sedimentology, micropalaeontology and radiocarbon sediment datations. First, we analysed the present ostracods spatial distribution in modern lagoons and river mouths in order to use this microfauna as a bioindicator of past environmental conditions in the study area. Various aquatic envi-ronments (60) from the NW Mediterranean coastline were studied. The present ostracod assemblages characterize different stages of isolation, from completely closed lagoons to widely open marine bays, as well as intra-lagoonal environmental variability in relation to the inlets and river mouth proximities. The proposed database can be used to reconstruct coastal geomorphologies and dynamics, such as the holocene evolution of delta and barrier-lagoon systems in the Gulf of Lion. Second, sedimentary recording studies have been used to analyse the Narbonne’s coastal evolution. This study is based on nine cores distributed over the southern and eastern deltaic branches of the Aude river. With theses results, it is possible to propose a palaeogeographic scenario associated with the environmental dynamics of the lower valley since 9500 years cal. BP. This same data informs us about the local context of the Holocene sea level rise during the 9500-6000 years cal. BP. Several issues are discussed such as : the Holocene’s transgressions of the Gulf of Lion’s lagoons, the extreme marine event near the bay head delta around 5200-5000 years cal. BP, and the Aude delta’s rapid progradation during the last millennium. Additionally, we identified two periods of lead enrichment; which are consistent with the major mining peaks known in Languedoc (beginning of the first century AD - beginning of the classical Middle ages) and suggest a record of fluctuating metallurgical activity

Full textThe sedimentary bars of the nearshore control the dynamics of the beaches. Understanding the couplingbetween aerial and submerged beaches is essential at a time when entire urban sectors of the Occitanie region are subject to erosion. Thequestion of beach topography thus appears to be a crucial knowledge to anticipate future changes induced by the global rise in mean sea level.The objective of this thesis is to contribute to the comprehension of the aerial beach/submerged beach systems and their interconnections, bylooking at the particular case of the Mediterranean coasts. This thesis is based on the study of a beach with a double crescentic nearshore barsystem: the beach of Leucate. Similar crescentic bar systems are present in the southern part of the Gulf of Lion (between Leucate and Argelès-sur-Mer), i.e. about 40 km of coastline. A first part of the work was dedicated to the morphodynamics of the aerial beach, in particular to itsevent and seasonal dynamics in relation to the atypical forcing of the region on the sites of Leucate and La Franqui (prevailing onshore wind,long periods of fair weather, short and intense storms). A specific part on the Leucate site was then devoted to quantify the wind transportinduced by the onshore wind (Tramontane), so characteristic of the area. The second part of the work concerned the underwater beach ofLeucate and its system of double festoon bars at different time scales (20 years, seasons, events). This work allowed us to identify the controlparameters and the morphological response of this Mediterranean system. This has also led to the study of the establishment and dynamics of athird system of proximal bars intercalated locally between the internal bar and near the coastline, the Low Beach Bars, which have been littlestudied until now. A third part is devoted to the interactions between the aerial beach and the underwater beach through two examples. Thecouplings between the coastline and the bars on the site of Leucate, and the more complex example of the grau of La Franqui in which thesecouplings control the position of the estuary and its dynamics.This work has led to the description of a model of aerial beach evolution on anevent-driven and seasonal scale, which can be applied to the beaches of the southern Gulf of Lion. The work on the underwater beach hasallowed to highlight a diversity of bar typologies (especially for the internal bar), and a dynamic of the double bar system characterized by astability of bars more important than in other environments. Regarding the couplings between these two compartments, we have highlighted theimpact of the couplings between the nearshore bars and the coastline whose morphology evolves according to the couplings

Full textThe aim of my PhD is to better understand the genesis of signals based on archaeal and bacterial membrane lipids, tetraethers, in coastal marine environments by studying two adjacent sedimentary archives taken from the Gulf of Lions and covering the last glacial cycle. These archives were taken from the relatively shallow upper continental slope, which receives substantial terrigenous inputs during glacial periods. The study site thus has accumulation rates of about one meter per thousand years during glacial periods, which allows me to study the abrupt variability of Quaternary climates in addition to their longer-term variability. First, I have considerably improved the analysis of tetraethers, by adopting a new method for isomer separation and by optimizing the analytical instrument and signal detection. Second, I have tested a novel oceanic paleothermometer based on hydroxylated tetraethers (RI-OH index) for the first time in the western Mediterranean Sea. Third, I have studied the origins of tetraethers and their responses to sea level variations. The novel oceanic paleothermometer gives particularly encouraging results despite terrigenous inputs. However, bacterial tetraethers have mixed origins and complex, non linear responses to sea level variations. Possible explanations include the complex sedimentary dynamics of the Gulf of Lions and biases in tetraether-based signals

Full textUnder effect of tectonical, eustatic and morphological factors, marine sediments mainly confined on the continental shelves, move to the slope and to the abyssal plain where they feed sedimentary bodies more or less extended. In the Gulf of Lions (north-western part of the Mediterranean), the Pyreneo-Languedocian Sedimentary Ridge, located at the foot of the Catalano-Languedocian slope is an enlarged sedimentary levee. It forms the southern levee of the Creus Cape valley and the western one of the Sète valley. This sedimentary ridge is characterised by dune-like structures which have mainly a hydro-sedimentary origin (sediment waves). Seismical, morphological and sedimentological studies conducted on the Ridge form a multi-scale study that allowed us to appreciate its original causes, the factors responsible for its construction during the Plioquaternary (salt tectonics, gravity flows, plastic deformation mechanisms) involving a new regional light

Full textThe aim of this present work was firstly to study the nature and the reasons of spatio-temporal distribution of Artificial Reef (AR) fishes, secondly to analyze the fishing yield around the ARs and finally to characterize the AR users and their perceptions for this tool. Three AR localities of the Languedoc-Roussillon region (Northwestern Mediterranean Sea -France) were studied. The spatio-temporal evolution of fish communities was studied by underwater visual census. An increase of species richness with the AR age was detected. The habitat complexity was also identified such as a factor impacting the fish communities. At the regional level, the degree of isolation plays a role on fish communities of ARs. At the local level, the study suggest an effect of some environmental factors such as the presence of a river, the state of health of natural area in surroundings or the artisanal and recreational fishing pressures. The study of fishing yields providing of experimental fishing showed a higher yield in a radius of 300 m around ARs for hard substrate fishes and the fishing yield was higher at ARs than at natural reefs. Thus, ARs appear as a potential tool of sustain for artisanal fishing. This was confirmed by the artisanal fishermen. Results of semi-directed interviews of AR users indicated a great satisfaction of AR as to sustain their professional activity. Other users use ARs but lower proportion but in the future this could be change. Thus, it is necessary for the planning of ARs to consider locally environmental factors, but also intrinsic to the AR such as complexity. The users perception must also be taken into account in any future governance of AR

Full textProblems in coastal environments are often linked to the position of the shoreline, which has moved for 6000 years. Gulf of Lion (Mediterranean Sea) is an exceptional natural laboratory for morphodynamical studies of the shoreline in microtidal environment, using the existence of coastal lagoons behind the barrier island and subtidal sandbars on the shoreface. Lagoons are environments where the sedimentary infill is well preserved. The sedimentary record can be used for the paleo-reconstruction of the lagoon and of the sandy barrier. The first goal of this work is to characterize the evolution of Thau lagoon and Sète sandy barrier from the sedimentary infill. Using data of seismic reflexion and sedimentary cores, three mains units have been described. The main steps of the lagoon edification have been reconstructed using the analyses and the datation of the sedimentary samples. Coast showing systems with two sandbars have been observed in meso- and macrotidal environments. Their study in microtidal environment is less abundant, that’s why the system of Leucate Beach has been studied since 2000. The second goal of this work is to propose a conceptual modeling based on the morphodynamics of the system, from geophysical and hydrodynamical data. This model is based on morphodynamic observed sequences, it is necessary to create two beach states which can be included in the usual classification. It shows the role of the significant wave height and the incidence of the waves in the morphodynamics of the system
