Federal marine specialists have concluded that Navy sonar was the most likely cause of the unusual stranding of melon-headed whales in a Hawaiian bay in 2004. The appearance of as many as 200 of the normally deep-diving whales in Hanalei Bay in Kauai occurred while a major American-Japanese sonar training exercise was taking place. The report is the latest in a series of scientific reviews linking traditional mid-frequency naval sonar to whale strandings. The active sonar used by navies sends out loud pings of sound that seem to frighten and disorient whales. The effect was documented off Greece in 1996 and established later during naval exercises in the Bahamas, off the Canary Islands and off Spain. In the 2000 Bahamas stranding, a local marine biologist collected some of the whales that died onshore and froze them for later study -- which helped NOAA conclude that sonar was the likely cause. Michael Jasny, a senior consultant with NRDC, said the NOAA report was worrisome. "Once again, the Navy's denial has been contradicted by the official government investigation. It's time for the Navy to stop this needless infliction of harm."
