Structure and evolution of the Bellsund Graben between Forlandsundet and Bellsund (Spitsbergen) based on marine seismic data

The area of investigation is located within the western Spitsbergen continental shelf region seaward of Isfjorden and Bellsund. Interpretation of the MCS data from the shelf region has been made along the seismic lines acquired by the University of Bergen (Norway) during the surveys SVALEX-2001, SVALEX-2002 and Van-Mijenfjorden-2005. In addition, we have used the seismic section along line 37 from the survey Svalbard BU-1981 and geo-seismic section based on line NP-FO85/11 published by Gabrielsen et al. (1992). A location map of the seismic profiles is shown in Fig. 2.
