Article Correctness Is Author's Responsibility: Tsunami reveals human noise pollution in Hawaiian waters

(Duke University) Spinner dolphins in bays along Hawaii's Kona Coast are subjected to underwater sound levels more than 16 times louder than natural due to noise pollution from ecotourism, sonar exercises and other human activities in the bays, a Duke University-led study finds. A tsunami struck the islands' coastal waters during the study and temporarily halted most human activities there, providing scientists with a rare comparative glimpse into what the bays sound like without these disruptions.
