Thursday, November 3, 2016, 5:27 PM - People in Canada's Arctic are straining for an explanation for a mysterious sound detected off Baffin Island.
CBC News reports says local hunters, from the nearby community of Igloolik, describe the sound as a "ping" or "hum," apparently coming from the sea floor in the Fury and Hecla Strait,
a narrow waterway that separates northern Baffin Island from mainland Nunavut.
CBC says there have been a few theories floated around as the the source of the noise, including sonar surveys by a nearby mining company (the company in question, Baffinland, says it hasn't conducted any this summer). Another theory: A deliberate attempt by Greenpeace or other environmental groups to drive away wildlife to save them from the hunters, which Greenpeace has denied.
"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," spokeswoman Farrah Khan told the CBC.
Canada is no stranger to unexplained sounds, with the most famous being the Windsor Hum, though evidence suggests it may be just one manifestation of a more general "world hum."
