Researcher calls sonar tests OK The study finds thatunderwater noise does not drive away marine mammals By Helen Altonn haltonn@starbulletin.com Low-frequency sounds being emitted in an ocean study off North Kauai aren't keeping whales away or deterring them from reproducing, says researcher Joseph Mobley. Overall, he said, "Our findings were basically benign, so it's likely the National Marine Fisheries Service will have no problem with it." Mobley conducted eight aerial surveys this year to monitor effects on marine mammals of underwater noise from the Scripps Institution of Oceanography's North Pacific Acoustic Laboratory on Kauai. He then compared the findings with results of an aerial survey last year when the sound source was off. The University of Hawaii-West Oahu psychology professor is the lead UH researcher for marine mammal monitoring studies conducted for the Acoustic Thermometry of Ocean Climate (ATOC) project. The five-year program is designed to study ocean temperatures with sound transmissions over long distances. Testing began in January with final Navy approval and is done every four days with six 20-minute transmissions in one day. The research has been controversial because of concerns about effects of the sounds on humpback whales, although scientists reported no significant effects in two years of preliminary tests.
