Data sets

High-resolution multi-channel seismic reflection (MCS) profiles from the southeastern North Sea acquired during expedition MSM98/2 A. Lohrberg, J. Schneider von Deimling, H. Grob, K.-F. Lenz, and Krastel, S. https://doi.org/10.1594/PANGAEA.957181

Short summary

We present an update on the distribution of tunnel valleys in the southeastern North Sea between Amrum and Heligoland based on active seismic data. Our results demonstrate that very dense grids of seismic profiles are needed to understand the distribution and the formation of tunnel valleys in a given region. We also demonstrate that acquiring offshore active seismic data is time- and cost-effective to learn more about the formation and filling of tunnel valleys in different geological settings.
