"Ocean surface waves and currents can interact to produce strong seabed shear stress and mobilization of sediments that can significantly impact the seabed stability and benthic habitats on continental shelves. Therefore the knowledge of the magnitude and frequency of seabed disturbance by waves and currents and the resulting mobilization of sediment on continental shelves is critical for the spatial planning and management of Canada's offshore lands. Modelled waves, near-bottom tidal current and circulation current data for a 3-year period were used in a widely applied sediment transport module to simulate the seabed shear stresses and the mobilization of observed sediment grain size for the Scotian Shelf bioregion. The modelling results are presented and analyzed to derive updated understanding of seabed disturbance and sediment mobility on the Scotian Shelf"--Summary, page 1. Sediment transport Scotian Shelf.
