Supplementary Data for a Feasibility Study on Boulder Detection in the Shallow Sub-Seafloor with Beamforming on Ultra-High Resolution Seismic Data

Ultra high resolution multi channel seismic and multi-beam echo sounder data has been collected during the expedition He525 with R/V Heincke in March 2019 to conduct a feasibility study on boulder detection in the shallow sub-seafloor with beamforming on ultra-high resolution seismic data. The campaign of one week took place in the north of Helgoland in the German North Sea sector.
