What is making mysterious pinging noise in the Artic?


Canadian military personnel are probing what is making a strange pinging sound which has been heard coming from the sea floor in the Arctic.
The mysterious noise is said to have been reported by a number of local people, and there are reports that animals are fleeing as a result of the sound.
Officials have sent out a military aircraft to carry out multi-sensor searches in the area.
But, so far, the cause of the noise remains unknown.
A statement released by the Canadian military said: “The [aircraft] crew did not detect any surface or sub-surface contacts.The only thing the crew did observe were two pods of whales and six walruses in the area of interest.”
The noise is so loud that local people say they can even hear it through the hulls of their boats.
Described as a “hum” or a “beep” the sound was also heard through the summer near the hamlet of Igloolik.
The area where the noises are emulating from is a narrow channel of water near Greenland.
Canadian legislative assembly member Paul Quassa said: “It’s one of the major hunting areas in the summer and winter because it’s an area of open water surrounded by ice that’s abundant with sea mammals. And this time around, this summer, there were hardly any. And this became a suspicious thing.”
The area of sea is usually a migratory route for wildlife including seals and bowhead whales.
So far, there has been much speculation about what is causing the noise, but no definitive answers.
Some suggestions include that it could be some sort of sonar survey being conducted by a mining company looking at commercial opportunities within the area.
It has also been suggested that the campaign group Greenpeace could be deliberately generating the odd noises in a bid to scare away wildlife from what has traditionally been a rich hunting ground for locals.
Another possibility, said theorists, is that it could be being caused by military operated submarines.
However, all of those theories have been denied. Mining companies have insisted they are not carrying out any work in that area while Greenpeace has moved to squash any notion that it is responsible, and the military say there are no submarines known to have been in that area.
A defence spokesman said: “The cause of the pings remains mired in mystery.”
