Abstract:
The Baltic Basin is known for its numerous Paleozoic hydrocarbon reservoirs. There is published evidence that hydrocarbons are leaking from the seafloor, however, little is known about the hydrocarbon migration pathways from Paleozoic source and reservoir rocks towards the seafloor and the escape structures. To investigate the processes related to fluid escape at the seafloor, we utilized a bathymetric map from the eastern margin of the Gotland Deep. The data was acquired during the 2021 M177 Meteor expedition led by the University of Hamburg.
Data acquisition was carried out using the hull-mounted SIMRAD EM710 multibeam swath sounder system, which operates in a frequency range between 70 and 100 kHz. The data was calibrated with the water velocity by using two sound velocity measurements. Data processing included manual removal of data errors and gridding with a grid size of 5 x 5 m. Due to bad weather during the acquisition and the resulting ship movements, some errors and artifacts (e.g. periodic wobbling) remained in the data even after intensive processing. The grids are available in UTM coordinates (UTM zone 34N).
