"Ocean surface waves and tidal 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 mobilisation of sediment on continental shelves is critical for the spatial planning and management of Canada's offshore lands. Modelled waves, tidal current and circulation current data for a 3-year period were used in a combined-flow sediment transport model to simulate the seabed shear stresses and the mobilization of observed sediment grain size on the Canadian Atlantic Shelf. The modelling results are presented and analyzed to derive updated framework of seabed disturbance and sediment mobility on the Atlantic Shelf"--Summary, page 1.
