Cruise 0103 with R/V Seisma to fjords in Sogn og Fjordane and Møre og Romsdal - cruise report

Abstract

This report summarises the work carried out during cruise 0103 to fjords in Sogn og Fjordane and Møre og Romsdal in June and July 2001 in the project \"Regional lanmdslide occurrences and possible postglacial earthquake activity in northwest Western Norway\" (Phase B1). This project is a collaboration between NGU, Norsk Hydro ASA. The University of Bergen and the Sogn and Fjordane College, aiming to identify regional slide events and interpret triggering factors for such slides. The cruise was a multipurpose cruise that involved testing of a newly developed vibrocorer (HYBAV) as well as sampling both for stratigraphical and environmen- tal (Heavy metals and dinocysts) purposes. Stratigraphical cores were retrieved at 31 locations during the cruise. In addition, two box cores and several stratigraphical cores, that were subsampled for environmental analyses, were retrieved. The cruise also involved four days of high resolution (Topas) seismic profiling. As number of technical challenges with the vibrocorer arouse throughout the cruise. The experiences with the corer will be reported elsewhere.
