Pockmarks, a paleo fluid efflux event, glacial meltwater channels, sponge colonies, and trawling impacts in Emerald Basin, Scotian Shelf : autonomous underwater vehicle surveys, William Kennedy 2022001... : M183-2/8933E-PDF
"The Geological Survey of Canada Atlantic (GSC-A) Gavia Autonomous Underwater Vehicle equipped with a dual frequency (540 kHz/1600 kHz) Edgetech 2205 bathymetric sidescan sonar system and a Teledyne Benthos 12-23 kHz sub-bottom profiler was successfully deployed on offshore Scotian Shelf sites. It surveyed three small areas: two that were across known benthic sponge, Vazella pourtalesii (Russian Hat), within a DFO directed trawling closure area on the SE flank of Sambro Bank, and one across a series of pockmarks, eroded cone-shaped depressions in soft mud due to fluid efflux"--Executive Summary, page 1.
