Abstract
Avalanche scars, landslide scree and debris flow tongues have been imaged in plan view on the continental slope of the western margin of the North Atlantic. Their detection and mapping has been accomplished with a tethered deep-ocean side-scan sonar having a swath width of 5 km. The sonar was constructed to search for and locate the wreck of the S. S. TITANIC (Wilford, 1980). We have subsequently used it in cooperation with the U.S. Geological Survey to explore the continental slope of New England and the mid-Atlantic margin of the United States (Robb et al., 1981, a, b; McGreggor et al., 1981).
