Summary(Plain Language Summary, not published)
In summer 2021, the GSC (Atlantic) team continued work on mapping seabed habitats and marine geohazards in the West Orphan Basin and northeast Newfoundland slope (Labrador Sea), and included the Northeast Newfoundland Slope Closure - an area known for high-density populations of deep-sea corals, sponges and sea pens. Objectives of this study were to ground-truth and date several submarine failures through piston coring, and to image unique habitats using the DeepImager - an upgraded underwater video system developed in-house. The work focussed on the northern part of Orphan Basin and on Orphan Spur.
