Abstract

This thesis presents diverse theoretical and practical applications of the ERS 1/2 and RADARSAT satellite images of the Synthetic Aperture Radar SAR sensor (near 330 images in the Northwest Mediterranean NWM and 980 in European coastal waters) Other types of satellite images were used to study the marine pollution and dynamics studies of the NWM and other European areas. Principal source of information constitutes a collection of the SAR images obtained on periodic form during the 1996-1998 years generally by the Clean Seas European project, also by the Oil Watch and the ERS-1/2 SAR Exploitation Study in Catalonia projects. The geographical area of interest includes the NWM maritime zone: Balearic Islands - Ebro Delta - Cap of Creus - Gulf of Leon - Marseilles - Balearic Islands. <br/>During the presents studies there we elaborated a thematic collection of the SAR (full and detailed fragments) images of the almost 300 oil spills and of the 42 coastal plumes detected in the NWM in the period 1996-1998 also thematic maps and the statistical analysis of their topologic characteristics and of their temporary/spatial occurrences were elaborated. <br/>The area of the all accidental spills and plumes that took place in the period 1996-1998 in the NWM was also estimated (the diameter is 146 km and it oil mass is 4.477 Tm), we made a comparative analysis of the results of the Clean Seas project from different zones of studies (NWM, North Sea, Baltic Sea) and the statistical analysis of the occurrence of disasters involving oil spills in European waters in base of the results of the present work and of the historical information of the past 34 years, relating them to Zipf's law. The general conclusion is that the small habitual oil spills play a significant role in the overall marine pollution due to its very frequent occurrence.<br/>In the area of study of the dynamics of the NWM we present the results of the topologic and spatial analysis of the vortices detected by the satellite sensors, the thematic maps, the comparison with the laboratory experiments, the quantitative analysis of the particularities of tide in different points of the NWM, the examples of the application of the multifractal analysis and also a practical method proposed in order to distinguish the sea surface structures of different origins.<br/>The obtained results have allowed to obtain a general and statistically justified vision of the level of the marine pollution of the NWM, as well as in other European maritime zones. It was also possible to obtain quantitative information on the complex superficial dynamics of the NWM, which can be useful to quantify the capacity of surface diffusion of the ocean.
