Which is precisely what SOSUS and previous versions of SURTASS did.
Looking at these assurances, and at the map in the OEIS/EIS of SURTASS LFA Sonar Potential Operating Areas (see graphic), one could logically reach the conclusion that SURTASS LFA is intended for use in the open ocean, much as SOSUS was used to detect the Soviet submarines of a generation ago.
But since SOSUS covered only a portion of the world ocean, PMEL launched a strategy to develop moored, autonomous hydrophones that could be deployed for long durations in the SOFAR channel to monitor seismicity in more remote ocean regions.
57) It is noted that "the SOSUS [Sound Surveillance] system substantially helped the U.
After World War II, that became an important matter; the United States constructed elaborate global networks of AUTOVON/AUTODIN communications, DSP and other satellite downlinks, the DEW Line and BMEWS, SOSUS, NUDETS, signals-intelligence ground installations, and much more.
AUTOVON/AUTODIN = Automatic Voice Network/Automatic Digital Network; DSP = Defense Satellite Program; DEW = Distant Early Warning; BMEWS = Ballistic Missile Early Warning System; SOSUS = Sound Surveillance System; NUDETS = Nuclear Detonation Detection and Reporting System.
Despite some SOSUS contacts in and to the south of the Greenland-Iceland--United Kingdom gap, none of the Foxtrots had been firmly tracked as of 25 October, when they reached their stations off Cuba.
These sensors included improved SOSUS arrays, towed arrays on American nuclear-powered attack submarines (SSNs), improved sonobuoys for P-3 and S-3 aircraft, and eventually towed arrays on surface combatants.

38) The lack of SOSUS capabilities in the Mediterranean was somewhat alleviated by the deployment of surface ships equipped with towed-array surveillance systems.
