Abstract
A small area west of Verrill Canyon on the Scotian Slope, between the Shubenacadie H-100 and Acadia K-62 deep-water well sites, was examined to address the question of whether sedimentological and geomechanical features of piston cores would explain the localized occurrence of sediment failures. The seabed in the area was divided into zones of disturbed, undisturbed, and erosional areas. Six continuous acoustic reflectors were traced throughout the area from high-resolution acoustic records. The acoustic surveys showed that failure planes are restricted to specific horizons. Nine sediment cores, providing a composite stratigraphy of the acoustic section, were described for lithological variation and measured for a suite of physical properties. Failure planes appear to correlate with sandier intervals in cores. This provides some predictive capabilities elsewhere on the slope.
