520 |aExpedition ARA04C was conducted from September 10 - September 26, 2013 to investigate the Canadian Beaufort Sea shelf and slope region. The expedition was carried out under the regional geo-hazard assessment project of the offshore Beaufort region within the Geological Survey of Canada's (GSC) Public Safety Program. During the expedition multichannel seismic data were collected that have been analysed to detect and map ice-bearing sediments using the seismic refraction technique. The results from the refraction velocity analysis allowed verification of major boundaries of permafrost or ice-bearing sediment occurrences from previous work carried out by the GSC in 1987, but also define several critical corrections, especially near the shelf edge zone.
