The Sound Surveillance System (SOSUS) is a multibillion-dollar network of hydrophone arrays mounted on the seafloor throughout the Atlantic and Pacific oceans.
The SOSUS system takes advantage of the sound channel that exists in the ocean, which allows low-frequency sound to travel great distances.
At the end of the Cold War, the Navy decided to allow this system to be used by scientists with suitable security clearances, in what was called “dual-use.” SOSUS is now used to study hydrothermal vents and pinpoint underwater volcanic eruptions. The system is also used to study the vocalizations of whales. Scientists can study and track whales in the Atlantic and Pacific oceans using the SOSUS hydrophone arrays. This system has also been used to measure ocean temperatures in relation to climate change. By measuring the travel time of sound waves, the SOSUS system is able record average ocean temperature changes over an ocean basin.
