Summary(Plain Language Summary, not published)
The Amundsen 2020804 (Amundsen Science 2020 Leg 2a) expedition took place in the northeast Newfoundland slope and northern Orphan Basin region between Latitudes 50.1 - 52.6 N and Longitudes 51.1 - 48.8 W. The expedition took place during August 14th - 24th 2020, departing from and returning to St. John's, Newfoundland on board CCGS Amundsen. The cruise activities consisted of sampling the seabed by collecting piston cores, gravity cores, box cores, grabs and bottom camera imagery during daylight hours and surveying the seabed using sub-bottom profiler and multibeam echosounder during night hours with sound velocity measurements taken along the track. The scientific objectives of the Amundsen 2020804 cruise included geological and habitat mapping, identification and dating of geological hazards, and gaining better understanding of geological controls on ecological processes. The sites of interest were located largely within the Northeast Newfoundland Slope Fishery Closure - an area known for high-density populations of deep-sea corals, sponges and sea pens.
