This report contains 15 maps (scale 1:1,5 million) presenting the geological database, bathymetry and various interpretations of the geology in the Norwegian Trench off southern Norway and the northern part of the adjacent North Sea Plateau. A short description is given for each map. The maps, made as a part of the Skagerrak Project (Longva & Thorsnes 1997, Ottesen et.al. 1996), have been extended further west and north, resulting in a map coverage from Langesund to Stavanger and west to 30E. The following maps are presented in the report: 1. Bathymetry 2. Side scan sonar interpretation and multibeam bathymetry 3. Seismic lines 4. Sea bed samples\/short cores 5. Depth to bedrock 6. Bedrock geology 7. Quaternary geology 8. Total thickness of Quaternary sediments 9. Thickness of pre-Late Weichselian sediments 10.Depth to Late Weichselian erosion surface 11.Thickness of upper unit of glaciomarine sediments 12.Thickness of Holocene sediments 13.Interpreted seismic profiles 14.Shallow gas and pockmarks 15.Sea bed sediments
