Résumé(Sommaire disponible en anglais seulement)
New multibeam and backscatter data were collected during Expedition ARA04C in key areas of the study zone. These data will help advance the scientific understanding of the degrading permafrost on the shelf and at the shelf edge, the nature of pingo-like features (PLFs), deep-water fluid expulsion zones, and the eastern-shelf of the Mackenzie Trough and its deep-water extension area. Data are of general high quality revealing formerly unknown details, such as the Mackenzie Trough "Gary Knolls" zone with many PLFs and moats, the canyon-type setting of the deep-water Mackenzie Trough, as well as a newly developing mud volcano site. Post-processing of the backscatter data will be carried out at KOPRI and the GSC after the expedition and will be integrated with the multibeam data.
