Paleobathymetric reconstruction in the Hammerfest and Tromsø basins, southwestern Barents Sea
Seismic interpretation of 13 lines has been conducted in the Hammerfest and Tromsø basin areas in the southwestern Barents Sea. Based on interpretations, a 3D Geomodel comprising 10 layers has been constructed. Depth conversion of the Geomodel was accomplished after building of the herein required v...
