Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.
The sound's source was roughly triangulated to , a remote point in the South Pacific Ocean west of the southern tip of South AmericaThe sound was detected by the Equatorial Pacific Ocean autonomous hydrophone array, [1] a system of hydrophones primarily used to monitor undersea seismicity, ice noise, and marine mammal population and migration.
Chapman helped to analyze the data from the recordings in the 1980s and discovered the data contained a “gold mine” of information about many kinds of sound in the ocean, including from marine ...
Bio-duck sound. Bio-duck is a sound recorded in the Southern Ocean, specifically in Antarctic Waters and the West Coast of Australia. [1] [2] It was first reported in 1960 by submarine personnel, who gave the sound its name, associating it with that of a duck. [3]
The sound waves of a fin whale song is loud enough to penetrate Earth’s crust and assist with mapping the ocean floor, a new study has found. Singing fin whales can help map ocean floor: study ...

The western North Atlantic showing the locations of two experiments that employed ocean acoustic tomography. AMODE, the "Acoustic Mid-Ocean Dynamics Experiment" (1990-1), was designed to study ocean dynamics in an area away from the Gulf Stream, and SYNOP (1988-9) was designed to synoptically measure aspects of the Gulf Stream.
Experts refer to the temperature further below the surface as ocean temperature or deep ocean temperature. Ocean temperatures more than 20 metres below the surface vary by region and time. They contribute to variations in ocean heat content and ocean stratification. [11] The increase of both ocean surface temperature and deeper ocean ...
