The Bloop An ultra-low-frequency, high-amplitude underwater sound detected by NOAA in 1997. It rose in frequency over about a minute.
1 Sources 5 Connections NOAA The U.S. National Oceanic and Atmospheric Administration. It detected the sound, and its Vents Program attributed it to an ice quake.
1 Sources 3 Connections Pacific Marine Environmental Laboratory The NOAA laboratory that designed and built the hydrophone array that caught the sound.
1 Sources 2 Connections Equatorial Pacific hydrophone array Autonomous hydrophones placed to monitor undersea earthquakes, ice noise and marine mammal populations. They recorded the Bloop.
1 Sources 3 Connections SOSUS The U.S. Navy Sound Surveillance System, originally designed to detect Soviet submarines. NOAA's hydrophone array was built to augment its use of it.
1 Sources 1 Connections 50°S 100°W Where the sound was roughly triangulated: a remote point in the South Pacific west of the southern tip of South America.
1 Sources 1 Connections Ice quake A tremor from ice rather than rock, such as an iceberg calving or gouging the seabed. NOAA attributes the Bloop to a large one.
1 Sources 2 Connections Iceberg A53a An iceberg tracked as it broke up near South Georgia Island in early 2008. Ice quakes recorded while tracking it had spectrograms similar to the Bloop.
1 Sources 1 Connections Between Bransfield Strait and the Ross Sea The most likely location of the iceberg that made the sound, or possibly Cape Adare.
1 Sources 1 Connections The giant creature idea A 2002 magazine article amplified a scientist's "hunch" into talk of a giant creature. The same scientist had said in 2001 that he believed it was ice calving in Antarctica. By 2012 the animal idea had been replaced by ice.
