The survey was conducted from 4. to 14. september 2004, using RV G.O. SARS. The survey goals were:

• Sea-floor mapping of Isfjorden areas, continental slope, rift valley and Knipovich ridge, using the Simrad EM 1002 Multibeam sonar
• Sub-bottom profiling of the same areas, using the Simrad Topas instrument
• Seismic data acquisition over the margin, slope, rift valley and Knipovich ridge, using both a 3 km, 240 ch streamer and a single-channel streamer
• Collect gravitymeter data from all areas, using a LaCoste & Romberg marine gravitymeter, updated with ZLS Electronics.
• Collect Magnetometer data from all areas. The magnetometer, however, has not been fully commisioned for use on the new research vessel yet.
• Bottom coring samples from selected sites.
• ROV inspection of selected sites.
