| Summary | (Plain Language Summary, not published)
The objective of the CCGS Louis S. St. Laurent 2019 expedition was to carry acoustic survey of seabed along Northeast Newfoundland shelf and slope in
order to collect high-quality bathymetric and sub-surface reflection data, using multibeam echosounder and subbottom profiler. This information is critical for understanding seabed geomorphology, geological hazards as well as benthic habitats in the
region. The survey covered a significant part of DFO's NE Newfoundland fishery closure as well as ecologically and biologically significant areas known for high-density populations of deep-sea corals, sponges and sea pens. As a result of this cruise
Canadian North Atlantic multibeam coverage was augmented by about 13,000 square kilometers of new bathymetric data and more than 2400 line miles of sub-bottom profiler data. |
