Description: Ultra high resolution multi channel seismic data has been collected during the expedition He525 with R/V Heincke between 2019-03-05 and 2019-03-08 in the German North Sea to conduct a feasibility study on boulder detection in the shallow sub-seafloor with beamforming on ultra-high resolution seismic data. The campaign took place in the north of Helgoland where boulders on the seafloor have been identified. A digital solid-state streamer system (HTI) in a planar array set-up with 48 channels in a 8x3 m tow frame as well as a ultra high resolution seismic source (Applied Acoustics Dura-Spark 400 with a CSP-N 2400 Negative Discharge, 1750 J) were employed to acquire the profile GeoB19-112. The acquisition set-up is optimized for diffraction imaging but conventional seismic reflection imaging quality is limited. The data archived has been processed for diffraction imaging and thus boulder detection in a small area of interest (60x60 m). The archived Kingdom Porject required SQL 2012 (forward compatible, may require project updates).
