Full textDue to their dire impacts on marine life, public health, and services, accidental oil spills require an immediate response. Effective action starts with a good knowledge of the ocean dynamics prevailing in the contaminated region. The Lagrangian approach has been proposed as a supportive tool in marine pollution management. The goal of this thesis is to use and develop Lagrangian tools to analyze two oil spill events extending on a scale smaller than that of the DeepWater Horizon oil spill. These are an offshore East China sea oil spill (2018) and a near-coast East Mediterranean accident (2021). The calculation of Lagrangian fronts have been more robust and more informative on the dispersion pathways than the direct advection of a numerical tracer. The inclusion of the wind effect is also found to be essential, being capable of suddenly breaking Lagrangian fronts. A new technique is also proposed, rooted in the Lyapunov theory, by which the drifting speed of a Lagrangian front can be estimated based on near real-time information alone. This information allows to predict the Lagrangian front future location over a few days and to study frontal drifting speeds at global and Mediterranean scales. A further contribution to a Lagrangian experiment in the Mediterranean highlights the Lagrangian shortcoming of nadir altimetry and the need for future altimetry missions like SWOT

Full textPollutions of coastal areas by oil spills, where they occur, can have consequences on the environment and the coastal societies. This thesis proposes to assess the coastal vulnerability to pollution according to the seasons and in two very different sites: the coast of Pays de la Loire in France and the East coast of the Azov Sea in Russia. The objective is to identify issues that could be damaged and choose transposable variables, easy to obtain, in order to prioritize them. Many studies in the world have focused on coastal vulnerability at oil pollution since the end of the 1970s. First morphological, biological and economic indexes have been gradually integrated, before the development of a global vulnerability index. It appears that these indexes are often difficult to calculate because of the diversity, the absence or reliability of some data. Our assessment of the environmental sensitivity is based on three variables: the type and nature of substrate, the calculation the remanence in situ which is an innovation and the biological sensibility. Economic vulnerability is evaluated on two levels: first according to the duration of interruption to differentiate activities among themselves, then according to the number of workers to differentiate companies from each other. The mapping results suggest a new transposable approach to coastal vulnerability and represents a potential decision support tool

Full textThe present study treats with the contamination by hydrocarbons, with superficial sediments of various stations repartee on two sites : the bay of Skikda (situated in the Mediterranean Sea) and the Saf-Saf oued (in its part downstream) with flows into this bay.This contamiation was studied by point of view geographical distribution, origin and nature of hydrocarbons extracts. The contents in found hydrocarbons are slightly more raised in the Saf-Saf oued (278 mg.kg-1sed. dry), that in the site sea (200 mg.kg-1 sed. dry). Compared with other studies made in the Mediterranean Sea, our results testify of an average level of contamination. The identification of the main origins of hydrocarbons presents in sediments of both sites, was made by using several indications relative to hydrocarbons saturated and in aromatic polycyclic hydrocarbons. The values of these indications allowd to highlight several origins for hydrocarbons as well in the Saf-Saf oued, as in Skikda bay (originate biogenic natural terristerial and/or marine, originate natural or oil pyrolytic and oil origins). A statistical study made the object of a second part of this work, by means of series of analysisesand of one-various tests (ANOVA, Tukey and Dunnett applied to periods, then to the stations for each of 5 characteristics), two-various (study of the correlations) and several-various (MANOVA, ACP and hierarchical analysis). These tests were applied to the data of both sites of studies and allowed to confirm the results obtained in the first part of the work

Full textLebanon coastal zone (LCZ) which extends over 220 km along the Eastern Mediterranean Sea is a typical case of most coastal areas of the developing countries in the Mediterranean region, where the combination of a wide range of anthropogenic activities are contributing to water pollution and environmental degradation, by the direct and indirect release of a large number of pollutants into the sea via atmospheric and river inputs. Amongst the numerous environmental concerns we are facing, the marine environment is one of the top priorities that must be addressed. Due to its ecological importance, the evaluation of coastal sediment quality constitutes an important area of research to give a clear picture of water pollution status. Much attention was paid of some priority pollutants such as persistent organic pollutant (POPs) and heavy metals as known to be toxic, persistent and bio-accumulative, carcinogenic and mutagenic. There is an urgent need to survey the levels of these pollutants in sediments due to the great lack of information in the eastern part of the Mediterranean Sea in general and particularly in Lebanese coastal zone which render our study very important and useful regionally and locally by local authority and policy makers during coastal zone management. The semi-enclosed basins such as ports and bays are very vulnerable ecosystem where build-up greatly amount of these pollutants in sediments. This why we focus on our studies of the assessment of ports sediment quality of some possible hotspots where the re-suspension and oxidation of anoxic sediment occur frequently. A special attention was taken to Tripoli harbour which is the second Port of Lebanon due to its location near some reserved island. The pollution levels of LCZ by these pollutants are assigned as moderate to high. An emergency proposal plan was prepared for Tripoli Harbour, this will assists harbour authority to response for all fire and oil spill accidents as a first step for a durable development inside this promising harbor
