Following an official request by the Government of Nunavut, the Canadian Armed Forces conducted an aerial investigation into mysterious pinging sound, also described as a "hum" and "beep," coming from the seafloor in Fury and Hecla Strait, a remote Arctic region of northern Canada. The source of the sound reported by sailors and hunters since June, however, remains a mystery.
This passage is known for the presence of various types of seals and bowhead whales, marine species usually abundant in the well-known hunting region during winter and summer, but according to Paul Quassa, a member of the legislative assembly, the sound seems to be chasing away the animals. "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. This summer there are none" said George Qulaut, another area expert.
According to the Department of National Defence senior communications advisor, Ashley Lemire, 'a CP-140 Aurora aircraft flew to the region under the mandate of “Operation LIMPID” and recorded no artificial noises emanating from the area,' Nunatsiaq News quoted DND's email received November 3, 2016.
“The air crew performed various multi-sensor searches in the area, including an acoustic search for 1.5 hours, without detecting any acoustic anomalies. The crew did not detect any surface or subsurface contacts,” the statement continued.
The only thing the crew did observe were two pods of whales and six walruses in the area of interest.
According to the BBC, the Canadian press offered various explanations for the sound. From a sonar survey conducted by a mining company to military submarines and Greenpeace doing it deliberately to scare away wildlife from the rich hunting area.
All of them have denied involvement.
The cause of the pinging noise, which locals say can even be heard through the hulls of boats, remains a mystery, the department of national defense in Ottawa said.
