New York, January the house at the end of the street 22, 2014 - What is happening to the pilot whales in the Gulf of Mexico? If they ask for marine biologists, Coast Guard, researchers. the house at the end of the street In the space of just one month, three pods of whales were "stranded", and many have died. At this time, various research institutions and federal agencies are trying desperately to push deeper waters two herds who risk their lives.
One consisting the house at the end of the street of 28 whales, ran aground near the coast at the National Park Lovers Key. The other, with 23 whales, is further south, near the coast of Marco Island. Another herd of 50 specimens, the house at the end of the street had stalled last December in the shallow waters that embrace the vast Everglades National Park. In all three cases, ie, strandings have occurred the house at the end of the street along the southwest coast of Florida. Typically these mammals live at least thirty kilometers from the coast, in very deep water.
No one has yet found an explanation for strandings. But one thing the scientists are sure: these specimens have or had a state of bad health: "I am emaciated, clearly in distress," said the biologist Denise Boyd. Twenty of the pack in December died, and four have died in recent cases, two of which are for euthanasia because they were too ill and were suffering. Another biologist, Laura Englevy, the house at the end of the street the National Oceanic and Atmospheric Administration (NOAA), the federal agency in charge of the study of the oceans and the atmosphere, explains that the pilot whales live in "families very narrow." In the pack, are generally two choices that will be the rider with the other. If one of these is the beach, the others follow, and remain close, despite the risk, most likely "because they do not want to abandon it."
Consequently, it happens that in hunting the pilot end up too under the coast. And when that happens can become disoriented the house at the end of the street because their sonar does not work anymore as in the deep waters. Precisely for this reason, often the rescuers manage to push the whale out to sea, but then this is rispiaggia. In fact, if it has lost its bearings, is confused and staggering like a drunk person.
Strandings are not only a tragedy of our day: in the chronicles the house at the end of the street of the past centuries have been recorded numerous. But there is no doubt that have increased in recent decades: for example, the house at the end of the street just as in Florida will struggle to save the last two herds in New Zealand rescuers are trying to help the 53 survivors of a pod of 73 that was beached in the northern coast. It is suspected that the cause of the proliferation of this phenomenon is the increasing noise that man does in the oceans, especially with the sonar of military fleets. Extraneous noise prevents the natural sonar whales to function properly, we say that their GPS crazy.
And in fact, to help the two herds in crisis in Florida, the Coast Guard closed the traffic to the motor boats in a vast stretch of sea that surrounds them. In a dramatic race against time, the NOAA is doing autopsies of dead whales so far, to find some useful information. But no hiding that the hopes of saving them are limited.
