Abstract
The aim of the cruise was to (1) acquire high-resolution seismic data in areas with identified gas seepage sites in the Storbanken area to study the mechanisms controlling near-surface migration and seepage, (2) to complement the cross-disciplinary data repository by CAGE in this area, and (3) to search for seafloor seepage sites based on regional structural features (e.g., fault lineaments, glacio-tectonic features).
