Stranger Pings: Weird Noise Coming from Arctic Seafloor

A mysterious "pinging" noise is emanating from the seafloor in one of Canada's northernmost territories, and officials have yet to identify the source. The sound has been heard in recent months in the Fury and Hecla Strait, a channel of water in the Nunavut region of Canada. The Canadian Department of National Defence was informed of the strange noises and investigated the ping's origin, to no avail, reported the CBC.
