At Nunavut, Canada, a peculiar sound has been heard under water that locals can't explain. Beeping sound can be heard in Fury and Hecla Strait that comes from sea floor with a length of 75 miles northwest of Igloolik hamlet.

As reported in Express, Nuvanut's hunters are worried of the noise because it frightens different types of marine animals. They speculated that maybe the Greenpeace or the environmental activists are involved; however, they denied. Greenpeace Spokeswoman Farrah Khan said, "Not only would we not do anything to harm marine life, but we very much respect the right of Inuit to hunt and would definitely not want to impact that in any way," as per Express.

Based on Express reports, the Canadian military will be in charge to be able to identify the cause of this mystery. The Canadian Armed Forces spokesperson said that the Department of National Defence has been accordingly informed of the bizarre noises coming in the Fury and Hecla Strait area and they are taking the necessary steps to investigate the situation.

A member of the legislative assembly, Paul Quassa, told CBS that the area is hunting ground during summer and winter. He said: "This time around, this summer, there were hardly any (animals). And this became a suspicious thing." Meanwhile, according to Telegraph.co.uk, submarines were not considered a source of the noise but had not been ruled out yet, as per Department of National Defence. George Qulaut, member of the legislative assembly, also noticed the lack of wildlife.

"That passage is a migratory route for bowhead whales, and also bearded seals and ringed seals. There would be so many in that particular area," he told CBC News, as he recalled his old hunting days. "This summer there was none, he added."

The pinging has impelled various speculations. Aside from Greenpeace and the submarines, some are also pointing fingers to Baffinland Iron Mines Corporation, which has previously conducted sonar surveys of nearby. However, the company said they are not conducting any surveys in the area, and had no equipment in the water, as per Telegraph reports.
