The CAGE20-4 expedition on RV Helmer Hanssen targeted areas on the outer margins of the Møre and Vøring basins, with emphasis on IODP drilling proposal P944 sites. High-resolution 2D and 3D P-Cable seismic studies focused in particular on the structure of igneous deposits and how tectonic and igneous events have affected the Paleogene and global climate through gas production from organic-rich sediments and release into the atmosphere via hydrothermal venting. This expedition was part of a collaboration between CAGE and the Center for Earth Evolution and Dynamics (CEED) at the University of Oslo.
