Abstract
DREA has collected geoacoustic data to characterize the experimental areas for the Boundary 2001 sea-trial, in particular Sable Island Bank on the Scotian Shelf. Measurements include bathymetry, vertical incidence seismic reflection, sidescan sonar, wide angle reflection and bottom loss (WARBLE), grav samples, and geotechnical data using a cone penetrometer. The Scotian Shelf has numerous surficial seabed features that could create false targets, or "geoclutter", for tactical and low frequency active sonars. It has also been observed that the seabed at experimental location NS-1 is dynamic; bed forms have rotated or been destroyed in a six month interval between sidescan measurements.
