An underwater acoustic positioning system is a system for the tracking and navigation of underwater vehicles or divers by means of acoustic distance and/or direction measurements, and subsequent position triangulation. Underwater acoustic positioning systems are commonly used in a wide variety of underwater work, including oil and gas exploration, ocean sciences, salvage operations, marine archaeology, law enforcement and military activities.
Over a wide range of wavelengths the ocean is opaque to electromagnetic radiation but relatively transparent to sound. This property motivates a growing band of oceanographers to explore the possibilities of underwater acoustics as a tool for ocean measurement. At the largest scales, the temperature dependence of sound speed allows monitoring of path‐averaged temperature variability over ocean basin scales with great precision.
