Do not make noise when the whales sing (9 photos) Bashny.Net

On the coast of Australia again jumped whales. The amount of 200 pieces (194 whale and dolphin 6).
Draw and release could only 48.




WHY THEY DIE?

Why bottlenose, and with them the baleen whales, pilot whales, sperm whales,
Orca thrown onto dry land? What power makes them do it?

Since ancient times, science is struggling with the mystery mass death of cetaceans. There are many hypotheses. There are areas with special Mehta. Their only as "death zones" can not be called. This is the place where most often killed whales, dolphins. These black spots are both coasts of the USA, the Australian island of Tasmania, the southern coast of Chile, the coast of Tierra del Fuego ... And thrown something almost the same places. State of Tasmania is in first place in the world in the number of such tragedies. Over the past ten years off the coast of Tasmania, committed suicide about three thousand whales and dolphins. This is more than half of those killed in this way marine mammals worldwide.







Cetacean researcher at the University of Tasmania Mark Hindell believes that the death of cetaceans may be associated with changes in ocean currents, bringing to the coast of the fifth continent colder water and nutrients from the Antarctic ... There is a certain incompatibility.

Dutch scientist Van Heel horns concluded that shoaling due to an error radar apparatus does not receive the echo from a shallow soft bottom.

Toothed lose their orientation because of the ecological state of the sea water - its temperature effects. Or maybe it affects the phase of the moon, magnetic storms, climatic upheavals or, say, infrasound waves ...

Scientist from Cape Town Green suggested that the death of cetaceans on the shores of South Africa associated with unsuccessful attempts to track animals once existed historically Strait into the Indian Ocean, to whom they had enjoyed in the past ...







Wise Plutarch thought it was nothing more than an act of conscious suicide ...! Incidentally, this point of view, and in our time has been expressed by the famous conqueror depths Jacques Maillol. According to him, dolphins commit collective suicide in protest against the ill-mindlessly-man's relation to cetaceans. It is something like an act of self-immolation ...

Some scholars are inclined to the hypothesis of the so-called "Call of the Wild." The gist of it is that whales ostensibly - as the descendants of terrestrial creatures - with certain diseases manifest desire for "saving" the shore.

The hypothesis of "the call of death." Its general idea is as follows. In order to balance the diverse fauna, in every living specimens of the earth - two opposing entities: Life program and the program of self-destruction. Last "turned on" when boomers sharp rise in population, diseases, deviation ...

Group same emissions are likely due to the fact that the toothed no-no kind of fall into a trap - the zone of magnetic anomaly and disoriented, are on land. This is the conclusion of British scientists, who studied all the places of mass death of dolphins off the coast of the country, which, presumably, is not the kind of exceptional detail.

There is speculation that the whale drama somehow connected with military maneuvers. Sonar, I remind you, is a device used to detect submarines of the enemy. A snag here is this. Whale ear perceives sound over 110 decibels, but 180 of the eardrum bursts. A sonar volume reaches 215 decibels. So there is another hypothesis: the stunned animals lose their orientation in space, which leads to tragic consequences.







More and more evidence that an underwater explosion in the development of oil fields, strong noise emitted by icebreakers and military sonar noise harmful to hearing that whales are the main means of orientation. As a result, marine giants lose their ability to find each other using conventional signals, and therefore - to multiply. Keith, who became disabled, and sometimes can not even feed itself, is not capable of diving to a depth where his relatives usually find food. Noise interference will not give marine mammals to communicate with each other: they transmit information is distorted, "turn off" ... For this reason, the mother often can not determine the location of his child. Noises, scientists say cause hearing loss in whales and dolphins, as a result they are thrown on land.

Underwater world are threatened with extinction because of the noise ...

The behavior of whales and dolphins is clearly changing at a distance of hundreds of kilometers from the source of the noise. In short, the entire population of marine mammals is under the pressure of intense underwater noise. And find out the sad trend of the past 60 years, the noise level in the oceans has increased by two orders of magnitude!

In short, the problem of mass deaths of whales and dolphins actively studied for over 50 years. Especially in America. However, so far - one hypothesis, assumptions, judgments. From robust - to extravagant. And then all the new troubles. No scientist can comprehend why in recent years, emissions of cetaceans frequent, and especially - off the coast of New Zealand and the United States?
