'Seismic and acoustic imaging of fluid seepage structures in different sedimentological and tectonic settings in the Lower Congo Basin'
I work with multichannel seismic data, Parasound sediment echosounder as well as bathymetric data collected during several research cruises to the Lower Congo Basin, West Africa (M47/3, M56, M76/3a). My aim is to investigate the structure and processes at fluid seepage sites in the context of different sedimentation regimes and active salt tectonics in a passive margin setting. In the Lower Congo Basin, fluid and gas seepage is a common process as it is an active hydrocarbon basin. Processes that influence the distribution and activity of such seepage include sediment input from the Congo River and the impact of its canyon and deep-sea fan on the margin as well as active salt tectonics of Aptian evaporites. Salt movement in the subseafloor deforms the overlying sediments and forms migration pathways for hydrocarbons from deep reservoirs.
