View Available Hint(s)for Part E Radar from a satellite is used to detect slight variations in the sea surface, which correspond to topography at the sea floor. A ship emits sound waves that bounce off of the ocean floor and back to the ship. The wave travel time is used to calculate ocean depth. A ship uses multibeam sonar to produce robust, shaded relief bathymetry maps of continental shelves. Seismic signals produced from an explosion travel to the ocean floor, penetrate some layers, and reflect back to a receiver. A bathymetric survey conducted by a ship lowering a weighted rope at certain locations to ascertain ocean depth.
