SOSUS, an acronym for SOund SUrveillance System, was a chain of underwater listening posts located for the most part across the northern Atlantic Ocean near Greenland, Iceland and the United Kingdom -- the so-called GIUK gap.
SOSUS development was started by the Committee for Undersea Warfare in 1949, a panel formed by the Navy, in order to further research into anti-submarine warfare.
SOSUS in the North Pacific is currently being analyzed for low-frequency vocalizations from marine mammals living in the open ocean.

 SOSUS
SOSUS development was started by the Committee for Undersea Warfare in 1949, a panel formed by the U.S. Navy in order to further research into anti-submarine warfare.
In 1961 SOSUS tracked the USS George Washington from the United States all the way to the UK.
Most of the system in the Atlantic is now turned off, although some of the chains are being used to track the vocalizations of whales in various study projects.

Since the end of the Cold War, the Navy has found a new use for its high-tech Sound Surveillance System (SOSUS): it is sharing it with scientists for research in tracking and studying whales and other marine mammals.
With multiple hydrophones in each SOSUS location, Navy specialists could pinpoint the location of submarines anywhere in the ocean, and they could determine not just whether it was a submarine, but also what kind of submarine, how fast it was moving, and in what direction.
SOSUS is now one of the essential research tools used by the National Marine Mammals Laboratory.

The year 1957 also saw the extension of SOSUS to the Eastern Pacific, with the installation of NAVFACs and associated arrays at – from south to north – San Nicholas Island, Point Sur, and Centerville Beach, California; Coos Bay, Oregon; and Pacific Beach, Washington.
The primary threat against which SOSUS was originally designed was snorkeling Soviet diesel submarines at the surface, and the system’s key technical characteristics – such as frequency coverage – were established accordingly.
In a 1961 demonstration of the capabilities of the system, SOSUS tracked the USS George Washington (SSBN-598) across the North Atlantic on her first transit from the United States to the United Kingdom.

The basic physical phenomena subsequently exploited in SOSUS to achieve longer-range submarine tracking were only discovered in the late 1930s and not adequately understood until mid-way through the 1939-1945 war.
The first prototype of a full-size SOSUS installation – a 1,000-foot-long line array of 40 hydrophone elements in 240 fathoms of water – was deployed on the bottom off Eleuthera by a British cable layer in January 1952.
These early SOSUS line arrays were positioned on the sea floor at locations that accessed the deep sound channel and oriented at right angles to the expected threat axis.

First, the Navy has for now completed their repairs to the three coastal arrays (of the six total) we use to monitor Juan de Fuca Ridge earthquakes.
In addition, we have upgraded all three SOSUS processing workstations, upgraded the servers that transfer, beamform, and backup hydrophone data from Whidbey, added a 2-Terabyte hard-disk for temporary data storage (holds ~2 years of data), and added a gigabit network, all of which have significantly increased our data processing speed.

SOSUS is the Navy underwater sonar listening system that hears most subs in all the world's oceans.
We later discovered the SOSUS indications that the sub had gone down at 180.0 Lon x 40.0 Lat (about 2,000 miles NW of Hawaii) a point more than 300 miles off the course the Russians were searching.
Doing underwater explosions as part of the research related to the Scorpion sinking led John to speculate that the explosion recorded at 180x40 had to be very loud, not something caused by an air tank imploding.
