Multibeam sonar mapping in outer Frobisher Bay, 2017-2018
Multibeam sonar data and accompanying acoustic sub-bottom profile data were collected using the multibeam echosounder aboard the scientific icebreaker CCGS Amundsen. Particular focus in 2017 and 2018 mapping was on deep water troughs with apparent mega-scale glacial lineations (MSGL) in the northwest portion of outer Frobisher bay, and in the deep fault-bounded southwest margin of outer Frobisher bay.
