In Steve Alten's The Loch, the source of the Bloop is revealed to be a colony of giant, carnivorous eels, one of which lives in Loch Ness.The comic book Atomic Robo had Robo investigate the source of the Bloop for the NOAA in a deep sea submersible."The Big Bloop" plays an important role in Jean-Marie Blas de Roblès's novel Island of Point Nemo.The children's television animation The Deep Season 1 Episode 23 finds that the sound comes from a form of sentient coral.NOAA posted a refutation on their web site. A 2012 American made-for-TV thriller produced for Animal Planet and Discovery Channel in the form of a documentary titled Mermaids: The Body Found suggested the Bloop sound was evidence for the existence of mermaids or an unknown species in the oceans.The Bloop was one of the phenomena investigated in the second episode of the first season of Weird or What? on Discovery Canada.Over the last decade consensus has, in fact, supported the argument that the noise is produced by ice fracturing processes." : 175 In popular culture Is it even remotely possible that some creature bigger than any whale is lurking in the ocean depths? Or, perhaps more likely, something that is much more efficient at making sound? : 174–175Īccording to author Philip Hayward, Wolman's speculations "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. That means it must be far louder than any whale noise, or any other animal noise for that matter. There's one crucial difference, however: in 1997 Bloop was detected by sensors up to 4,800 km (3,000 mi) apart. Fox stated that while the audio profile of Bloop does resemble that of a living creature, the source was a mystery because it would be "far more powerful than the calls made by any animal on Earth." Wolman states in the article that Fox initially speculated Bloop to be ice calving in Antarctica, but later came to believe the sound to be like that of an animal in origin: įox's hunch is that the sound nicknamed Bloop is the most likely to come from some sort of animal, because its signature is a rapid variation in frequency similar to that of sounds known to be made by marine beasts. NOAA's Christopher Fox, interviewed by David Wolman for an article in New Scientist, did not believe its origin was man-made, such as a submarine or bomb, nor a familiar geological event such as a volcano or an earthquake. The acoustical signals emitted by this failure process are similar to those emitted from a collapsing air bubble in a fluid." : 121 Animal origin "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," : 137 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. : 121 According to Xie, both events will produce sound in the failure sequence (breakup) of an ice floe: : 137 Ridging occurs when that ice bends or slides at the ridges. Rubbing involves two or more areas of compacted glacial ice floes which are being forced together, inducing shear deformation at its edges and triggering horizontally-polarized shear waves, i. Two processes known as rubbing and ridging are responsible for acoustical emissions similar to those from ice calving. : 55 As oceanographer Yunbo Xie explains, the alteration of waveforms from a detected sound "can also be caused by so-called angular frequency dependent radiation patterns associated with antisymmetric mode motion of the ice cover." : 59 Rubbing and ridging events within an ice floe In ice calving, variations result from a sound source's own motion. ![]() ![]() Sounds generated by ice quakes are easily determined through the use of hydrophones since sea water, an excellent sound channel, allows the ambient sounds generated through ice activities to travel great distances. The iceberg(s) involved in generating the sound were most likely between Bransfield Straits and the Ross Sea or possibly at Cape Adare, a well-known source of cryogenic signals. This was found during the tracking of iceberg A53a as it disintegrated near South Georgia Island in early 2008. Numerous ice quakes share similar spectrograms with Bloop, as well as the amplitude necessary to detect them despite ranges exceeding 5000 km. The NOAA Vents Program has attributed the sound to that of a large cryoseism (also known as an ice quake). Problems playing this file? See media help.Īccording to the NOAA description, the sound "rose" in frequency over about one minute and was of sufficient amplitude to be heard on multiple sensors, at a range of over 5,000 km (3,000 mi).
