TPO-32 - Integrated Writing Task
Starting in the 1960s and continuing until the 1980s, sailors in Russian submarines patrolling the North Alantic 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 ocra 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 male are similar to those that the submarines were detecting.
A second idea is that the sounds were caused by giant squid. Giant squids are gaint 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 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.
The passage states an odd voice was heard in North arctic and arctic ocean for two decades by Russian submarine's crew. They called the voice quackers. The article proposes three possible theories for the source of the quackers but the lecturer refutes all the explanations.
First, the passage states that the quacker’s source is related to the ocra whales which attracting mates. The professor rejects this theory by saying that ocra whales live in superficial depth of ocean but the submarines are located in the profound parts of ocean so the voice of whales is not detectable by the submarines.
Second, the article explains that giant squid is the other specie which could emit the quackers. The lecturer does not substantiate this reason. She says that the sound was detected by the crews for two decades between 1960 to 1980 but giant squid lives in the ocean until now so it is not reasonable that it emits the voice in two decades and stops emission suddenly.
Third, the passage states that it could be emitted by a military equipment related to other countries. The professor repudiates the theory by saying that the quackers changes direction very fast but this maneuvering ability in not possible for even state-of-art submarines and in addition the engine voice of submarines could not be heard too and it is not possible even for very modern marine euipments.
