The National Oceanic and Atmospheric Administration (NOAA) of the United States discovered bloop, a very low-frequency, high-amplitude underwater sound, in 1997. By 2012, NOAA’s description of the sound as compatible with noises made via non-tectonic cryoseisms coming from glacial motions such as ice calving or through seafloor gouge by ice had superseded prior supposition that the sound emanated from a marine species.
Sound profile
The source of the sound was approximately located at 50°S 100°W, a distant location in the South Pacific Ocean to the west of South America’s southernmost point. The Equatorial Pacific Ocean autonomous hydrophone array, a network of hydrophones mainly intended to track marine animal population and movement, underwater seismicity, and ice noise, picked up the sound. The Pacific Marine Environmental Laboratory (PMEL) of NOAA developed this stand-alone system to supplement the agency’s usage of the U.S. Navy Sound Surveillance System (SOSUS), which was initially intended to detect Soviet submarines.
The NOAA report states that the sound “rose” in frequency over the course of roughly a minute and had enough loudness to be detected at a distance of more than 5,000 km (3,000 mi) by numerous sensors.
Ice quake origin
The sound has been identified as the result of a major cryoseism, or ice earthquake, by the NOAA Vents Program. Many ice earthquakes have spectrograms that resemble Bloop, and they also have the amplitude required to identify them at distances greater than 5,000 km (3,000 mi). This was discovered in early 2008 as iceberg A53a was being tracked as it broke off close to South Georgia Island.
The iceberg or icebergs responsible for the sound were probably around Cape Adare, a well-known cryogenic signal source, or between Bransfield Strait and the Ross Sea. Since saltwater is a superb sound channel and the ambient noises produced by ice activities may travel considerable distances, hydrophones are an easy way to detect sounds made by ice quakes.
Ice calving
Variations in ice calving are caused by the motion of a sound source. Large ice chunks breaking apart and moving can emit intense low-frequency noises that travel great distances in water during earthquakes. The Bloop’s unique auditory signature and broad detection range may be explained by this technique. The change in waveforms from a detected sound “may also be caused by so-called angular frequency-dependent radiation patterns associated with antisymmetric mode motion of the ice cover,” according to oceanographer Yunbo Xie.
Rubbing and ridging events within an ice floe
Noises resembling those produced by ice calving are produced by two processes called rubbing and ridging. Rubbing is the process of forcing two or more compacted glacial ice floe sections together, which results in shear deformation at the edges and horizontally polarized shear waves, or SH waves. When the ice slips or bends at the ridges, ridgelining happens. Both of these, in Xie’s opinion, will result in sound during an ice floe’s failure sequence (breakup):
While “ridging deformation(s) revealed by this event indicate that the failure process is associated with a crushing process that seals air or vacuous gaps between ice floes, a wave equation resulting from shear deformation will be defined in an ice floe with the rubbing effect coupled to the floe through its boundary with the adjacent ice.” This failure process produces acoustical signals that resemble the sounds produced by an air bubble in a fluid collapsing.
Animal origin
In a 2001 interview with CNN, Christopher Fox of NOAA indicated that he thought Bloop was Antarctic ice calving. During an interview with David Wolman for a New Scientist story in 2002, Fox expressed his belief that the source of the phenomenon could not have been human-made, such as a bomb or submarine. Although Bloop’s acoustic profile does like that of a live thing, Fox added that it is unclear where the source came from because it would be “far more powerful than the calls made by any animal on Earth.” In his essay, Wolman stated the following:
Based on its quick shift in frequency signature, which is reminiscent of sounds known to be created by marine creatures, Fox believes that the sound dubbed Bloop is the most likely to be an animal, out of all the recorded unexplained sounds. One significant distinction exists, though: in 1997, sensors as far apart as 4,800 km (3,000 mi) were able to detect Bloop. It must thus be far louder than the sounds made by whales or any other animal. Is it really feasible that some animal larger than a whale is hiding down in the depths of the ocean? Or, maybe more likely, something with far greater audio fidelity?
— David Wolman
Wolman’s theories “amplified Fox’s ‘hunch’ and—through the use of the word ‘likely’—opened the door for subsequent speculation as to what such an ‘efficient’ noise-making entity might be,” according to author Philip Hayward. The claim that the noise is caused by ice fracture processes has received widespread acceptance within the past ten years.”
