Starting in the 1960s and continuing until the 1980s, sailors in Russian submarines patrolling the North Atlantic and Arctic Ocean would occasionally hear strange sounds. These underwater noises reminded the submarine crews of frog croaks, so they called the sounds “quackers” (from the Russian word for frog sounds). The sources of the sound seemed to be moving with great speed and agility; however, the submarines’ sonar (a method of detecting objects underwater) was unable to detect any solid moving objects in the area. There are several theories about what might have caused the odd sounds.
The first theory suggests that the strange noises were actually the calls of male and female orca whales during a courtship ritual. Orca whales are known to inhabit the areas where the submarines were picking up the bizarre noises. Orcas have been studied extensively, and the sounds they make when trying to attract a mate are similar to those that the submarines were detecting.
A second idea is that the sounds were caused by giant squid. Giant squid are giant marine invertebrates that live deep in the ocean and prey on large fish. They are difficult to detect by sonar because they have soft bodies with no skeleton. Not much is known about giant squid behavior, but their complex brains suggest they are intelligent animals. It is possible they have the ability to emit sound, and perhaps they approached the submarines out of curiosity.
A third theory suggests the Russian submarines were picking up stray sounds from some military technology, like another country’s submarines that were secretly patrolling the area. Perhaps the foreign submarines did not register on the sonar because they were using a kind of technology specifically designed to make them undetectable by sonar. The strange froglike sounds may have been emitted by the foreign submarines unintentionally.
When it comes to the source of odd sounds detected by Russian submarines from 1960s to 1980s, the speaker completely refutes the information from the reading material.
Initially, the author claims that the strange noises derived from the call of orca whales attracting a mate, which is similar to the sounds that the submarines found. However, the lecturer holds an opposite view. To be specific, it is known to us that orca whales live in the surface of ocean instead of deep sea where submarines usually sail. Evidently, those noises detected by those russia submarines in the deep sea could not be the voice of orcas who muttered on the surface.
In addition, in the passage, giant squid was brought under suspicion for the reason that they might emit some sound and even approach the submarines. The professor, nevertheless, argues against this viewpoint. To elaborate, the hazard occurred during only ten years, whereas if there are giant squid in that area, the noise would not disappear in ten years because they hardly migrate where they live for many years. As a result, the sound would continue for decades, which conflicts with the theory stated by the author.
Lastly, the writer professes that the sound was made by other submarines that were secretly patrolling in the deep sea. But from the listening, we know that direction of a submarine cannot change fast and acutely. While the sonar suggested that this object could divert its direction easily. Moreover, the engine of submarines are always accompanied with tremendous noise, which, as a matter of fact, these russia submarines did not find at that time. So it is self-evident that this state made by the author is totally wrong.
