The monster of the Mariana trench: Experiment in the Pacific attracted unknown animal
The deepest portion of the Pacific Ocean, the Challenger Deep, is located in the Mariana Trench in the western Pacific.
Recently, Japanese researchers have conducted an interesting experiment in the Suruga Bay, not far from the Mariana Trench, the deepest spot in the World Ocean.
The researchers put a container with some smelly bait on the bay bottom. A special video camera was attached to the wall of the container. The researchers peered into monitors to see what would happen with the container and the bait.
The smell of the bait attracted a shoal of deep-water sharks. But then the researchers saw something incredible that left them speechless. Suddenly the sharks scattered in all directions and researchers saw an incredibly huge monster on the screens of their monitors.
The giant slowly soared before the video camera at a depth of about 1.5 kilometers. The length of the sea Goliath was over 60 meters (more than 180 feet). It was not clear what the giant was in fact.
Researchers failed to answer the question, just made conjectures concerning what the creature may be. They said that might be a sleeping shark, the largest shark . Even now people know just few facts about these sharks.
They have been hiding in the dark ocean deeps for millions of years. People have never seen live sleeping sharks as well as giant squids. Only once, in 1964, a bulk of a dead sleeping shark was cast ashore in Indonesia; it was just a very young shark judging by its size of 26 meters. ..PRAVDA 9/20/03
"Scientists still do not know what they saw, registered and filmed and not a single frame has been released. If it was a giant shark Megalodon is a good candidate, even though this monster is thought to have died out 170 million years ago; see our features Megalodon the Monster Shark and New Evidence for Megalodon.
If it was a classical sea serpent it´s easy to understand why the Japanese scientist´s are cautious and would like to analyze the video footage very careful before releasing it to the world.
What's Bigger Than A Whale and Goes: Bloop?
Scientists Mystified by Monster Sound in Deep Sea
June 13, 2002LONDON, England -- Scientists have revealed a mysterious recording that they say could be the sound of a giant beast lurking in the depths of the ocean.
Researchers have nicknamed the strange unidentified sound picked up by undersea microphones "Bloop."
While it bears the varying frequency hallmark of marine animals, it is far more powerful than the calls made by any creature known on Earth, Britain's New Scientist reported on Thursday.
It is too big for a whale and one theory is that it is a deep sea monster, possibly a many-tentacled giant squid.
In 1997, Bloop was detected by U.S. Navy "spy" sensors 3,000 miles apart that had been put there to detect the movement of Soviet submarines, the magazine reports.
The frequency of the sound meant it had to be much louder than any recognised animal noise, including that produced by the largest whales.So is it a huge octopus? Although dead giant squid have been washed up on beaches, and tell-tale sucker marks have been seen on whales, there has never been a confirmed sighting of one of the elusive cephalopods in the wild.
The largest dead squid on record measured about 60ft including the length of its tentacles, but no one knows how big the creatures might grow.
For years sailors have told tales of monsters of the deep including the huge, many-tentacled kraken that could reach as high as a ship's mainmast and sink the biggest ships.
However Phil Lobel, a marine biologist at Boston University, Massachusetts, doubts that giant squid are the source of Bloop.
"Cephalopods have no gas-filled sac, so they have no way to make that type of noise," he said. "Though you can never rule anything out completely, I doubt it."
Scientists from the U.S.'s NOAA have been baffled by the "Bloop" sound Nevertheless he agrees that the sound is most likely to be biological in origin.
The system picking up Bloop and other strange noises from the deep is a military relic of the Cold War.
In the 1960s the U.S. Navy set up an array of underwater microphones, or hydrophones, around the globe to track Soviet submarines. The network was known as SOSUS, short for Sound Surveillance System.
The listening stations lie hundreds of yards below the ocean surface, at a depth where sound waves become trapped in a layer of water known as the "deep sound channel".
Here temperature and pressure cause sound waves to keep travelling without being scattered by the ocean surface or bottom.
Most of the sounds detected obviously emanate from whales, ships or earthquakes, but some very low frequency noises have proved baffling.
Scientist Christopher Fox of the U.S. National Oceanic and Atmospheric Administration's Acoustic Monitoring Project at Portland, Oregon, has given the signals names such as Train, Whistle, Slowdown, Upsweep and even Gregorian Chant.
He told New Scientist that most can be explained by ocean currents, volcanic activity -- Upsweep was tracked to an undersea South Pacific mountain that had not been identified as "live."
"The sound waves are almost like voice prints. You're able to look at the characteristics of the sound and say: 'There's a blue whale, there's a fin whale, there's a boat, there's a humpback whale and here comes and earchquake," he says.
But some sounds remain a mystery he says. Like Bloop -- monster of the deep?
