The scientists investigated the types of sediment found on the upper and middle slopes off the coast of Nova Scotia, Canada. They discovered a mix of mud, sand, and gravelly mud caused by massive movements and underwater currents. The steep upper slope and channel edge mostly have thick sandy layers with some mud in between. The middle slope's smaller, hilly areas contain thinner sandy layers and slumped beds. In the lower sections, there are frequent sandy layers with just a bit of mud, forming lobes. In stable areas, there's a mix of bioturbated mud and sandy mud. This study shows that different parts of the slope have unique sediment patterns formed by various processes.
