Scientific Interest
My research interests lie mainly with the geoscientific applications of multichannel seismic methods as well as other acoustic methods.
| Fluid flow systems | Fluid migration, fault systems, pockmark formation, salt tectonics, seafloor seepage, gas hydrates | Lower Congo Basin |
| Hydrothermal circulation through sediments and oceanic crust | Juan de Fuca plate | |
| Sedimentary systems | The impact of slope failures on sediment-ocean current interaction and resulting slope sedimentation | Namibia |
| Distribution of fluvial sediment input along a continental margin by ocean currents | Mozambique | |
| Water column | Automatic mapping of water column anomalies (e.g. gas bubble streams) | North Sea, Lower Congo Basin |
Projects
| since 2017 | Boulderdetection | Boulders in the sub-surface represent important obstacles to offshore foundations for e.g. wind farms. The Boulderdetection project aims at developing new methods for the localization of such boulders in sub-seafloor depths of several tens of meters. The project is funded by the BMWi and located at the Faculty of Geosciences in cooperation with Fraunhofer IWES and industry partners. I am involved in developing new beamforming methods using standard seismic sources and available acquisition equipment suitable for sub-seafloor imaging. |
| 2014 - 2017 | IMGAM | This BMWi project developed a new Autonomous Underwater Vehicle (AUV) that uses a multibeam echosounder to automatically image and localize gas bubble streams in the water column and also automatically samples the gas using an autoclave system. I mainly developed algorithms for the detection and localization of water column anomalies in multibeam echosounder data in order to localize the seep sites. |
| 2010 - 2014 | Fluid flow in the Lower Congo Basin | Dissertation within the GB project of MARUM: ‘Seismic and acoustic signatures of fluid seepage sites in different tectonic and sedimentary environments' |
