This chapter discusses the use of sound or acoustics for exploring the sea and for understanding the life histories of marine organisms. It describes how acoustics is used for surveying deep ocean landscapes and migrations in diverse fauna living below the surface waters. The chapter discusses sonar, or echo sounding, which is used by ships to measure the depth of the ocean or to find fish. It also looks at marine bioacoustics, a field of study concerned with organisms making and detecting sound in the sea. The chapter furthermore discusses how fishes produce noise, and examines the mechanism of echo-hunting or echolocation by dolphins.
