Dr. Stefan WENAU
in the MTU working group 2010-2019.
Now at Fraunhofer IWES as Senior Scientist
My research interests lie mainly with marine 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, North Sea
|The impact of slope failures on sediment-ocean current interaction and resulting slope sedimentation
|Distribution of fluvial sediment input along a continental margin by ocean currents
|Water column acoustics
|Acoustic gas bubble imaging, automatic detection
|Geophysical site surveys
|Shallow seismic and acoustic imaging, Boulderdetection
|North Sea, Baltic Sea
|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.
|IMGAM - Intelligentes Monitoring von klimaschädlichen CO2 / CH4 Gasaustritten im Meer
|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.
