Various Recordings from the Oceanic Depths 1

Recordings from the National Oceanic and Atmospheric Administration (NOAA). Using the SOSUS system - SOund SUrveillance System operated by the US Navy to track Soviet submarines during the Cold War. Many military-tech like sonar have been handed in 1970s for civilian use. The SOSUS system today serves the scientific community.

The video is separated into four parts.
Part 1 - Sounds of Marine Mammals (ie. whales)
Part 2 - Man-made (ie. boats, ships)
Part 3 - Natural (ie. earthquakes, tremors)
Part 4 - Unidentified Sounds

The recordings are usually sped up 10x-16x to be audibly discernible. Part IV unidentified sounds are recordings containing unique audio signatures that are uncategorized and are inconclusive. They are only given nicknames.
