Mysterious Noise Emanating From Arctic Sea Floor

A strange noise — described as a "ping," "hum" or "beep" — reportedly coming from the bottom of the sea in one of Canada’s northern territories has locals and officials mystified.

The sound has been heard throughout Fury and Hecla strait, a channel of water in the Nunavut region, a remote area in the northernmost territory of Canada, where some residents rely on hunting for their food, CBC News reported. 

According to Canadian news outlet, a decline in sea mammals in the area noted over the summer has been attributed to the strange noise, which is supposedly audible through the hulls of boats.

"That passage is a migratory route for bowhead whales, and also bearded seals and ringed seals," a member of the Legislative Assembly, George Qualut, told CBC News.

"There would be so many in that particular area. This summer there was none."

Speculation over the source of the noise has included Baffinland Iron Mines Corp.'s mining activity to the conservation work of Greenpeace. Both organizations have denied any involvement, according to CBC News.

The Canadian Department of National Defense is also investigating, CBC News reported.

"As of today, we're still working on it," Qualut told the news outlet. "We don't have a single clue."
