Navy Growler jet noise loud enough to reach orca pods even 100 feet underwater, research shows

SEATTLE — On the beaches, in the deepest reaches of the backcountry — even nearly 100 feet underwater — the noise of Navy Growler training jets is unescapable for people and even endangered southern resident orcas, new scientific research shows. In a paper published in the Journal of Marine Science and Engineering, scientists reported an underwater microphone anchored in nearly 100 feet of water offshore of the runway at Naval Air Station Whidbey Island distinctly picked up the sound of the jets, at levels known to affect orca behavior. To the orcas at that depth, the noise is about as loud as…
