In this movie, a survey ship uses a multibeam sonar and a side scan sonar. Multibeam measures the depth of the sea floor and the side scan identifies items on the sea floor. Scientists use the multibeam soundings to create rainbow-colored maps that depict the depth of the Sea floor. The side scan sonar paints a black and white image.
