Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
University of WashingtonScientists report that underwater noise pollution — from both large and small vessels — forces northern and southern resident orcas to expend more time and energy hunting for fish. The din also lowers the overall success of their hunting efforts. Noise from ships likely has an outsized impact on southern resident orca pods, which spend more time in areas with high ship traffic.
