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

The noise of Navy Growler jet training flights even 100 feet underwater is louder than levels made by vessels and noisy enough to force orcas to call louder to be heard and disrupt feeding. A new paper looked at jet noise at Naval Air Station Whidbey Island.
