Recently, some odd sounds, called quackers, were detected by Russian sailors in North Alantic and Artic Ocean. However, these sounds could not be distinguished by the sonar. In this case, the article proposes three possible theories about the origins of these sounds. However, none of these three theories are in favor by the professor since all of them are problematic from the viewpoints of professor.
First, the article suggests that quackers might be made from some special courtship rituals of Orca whales because males Orca whales usually use this kind of sounds, which is quite similar to these odd sounds detected by submarines, to attract the females. However, the professor points out that altought this theory of Orca seems to be possible, it is unlikely to happen. As the materials shown by the professor, the Orca whales live near the surface of the oceans while the submarines dive deeply into the seas to operte. Thus, these sounds could not be tracked by the sonars. What\'s more, this kind of whales are so massive that they could be seen by the detectors.
Then, the article states that this sounds would be produced by the giant squid, a kind of deep sea specie with soft body and no skeletons, which makes it quite difficult for sonars to detect it. But it\'s a tatally different case when it comes to the points of professor, the sounds of squids was first tracked by the sonars during 1960s. However, it has disappered since 1980s. Therefore, it would not be certain that why the squid appeared and disappear and it could not be the origin of the sounds.
Third, as the article shown, this sounds would be from some military technology of other country, which has not been registered in the sonars, making it unable to be detected. Nevertheless, as it described by the materials from the professor, the sounds moved around and changed its directions when being tracked. Therefore, it could not be the sounds of the submarines, because there would not be such a fast submarine without engine noises.
In a nutshell, the origin of these odd sounds are still unknown and it need more evidences.
