Le bassin profond du Bas-Congo est une marge passive affectée par une forte déformation salifère. Elle présente des sorties naturelles d'hydrocarbures lourds qui ont des impacts majeurs sociétaux, biologique, écologique et économique. L'objectif de ce travail est de comprendre les modes de fonctionnement de ces systèmes, depuis la mobilisation des hydrocarbures dans les sédiments, jusqu'à l'exutoire en fond de mer, puis en surface mer. Cette étude combine des analyses de données issues de l’imagerie spatiale, de l’océanographie, de la géochimie et de la géophysique marine afin d'obtenir à une vision intégrée multi-échelle des zones d’expulsion naturelles d'hydrocarbures dans le bassin profond du Bas-Congo. L'analyse de données issues de l'i...
