The canyon head lies just offshore of Moss Landing on the Central California coast. When they mapped out an area near Hawaii, they noticed it was a humongous landslide. The multibeam sonar produces high-resolution bathymetry (analogous to topography on land), the sidescan sonars produce imagery based on the intensity of the sound energy's reflections, and the subbottom profiler penetrates sediments on the seafloor, allowing the detection of sediment layers, faults, and depth to the basement rock. The topography of the ocean surface mimics the rises and dips of the ocean floor due to the gravitational pull. Go back to see more maps of. History of the Oregon Wine Industry The. Procedure.
