SOSUS, an acronym for sound surveillance system, is a chain of underwater listening posts located around the world in places such as the Atlantic Ocean near Greenland, Iceland and the United Kingdom—the GIUK gap—and at various locations in the Pacific Ocean. The United States Navy's initial intent for the system was for tracking Soviet submarines, which had to pass through the gap to attack targets further west. It was later supplemented by mobile assets such as the Surveillance Towed Array Sensor System (SURTASS), and became part of the Integrated Undersea Surveillance System (IUSS).

2008；By James Martin and Claudio Bagaini
Since that first step with reflection seismology was made almost a century ago一個世紀前就已經研究這門音波反射, geoscientists have taken thousands of steps toward a destination that many have characterized as the ultimate goal: reliable prediction of reservoir properties from surface seismic analysis.
