Hawaii incident intensifies debate on ocean noise
By Marc Kaufman, Washington Post | September 1, 2004
The Navy has acknowledged that vessels on maneuver off Hawaii in July used their sonar periodically in the 20 hours before a large pod of melon-headed whales unexpectedly came to shore in the area. The acknowledgment added to an already contentious debate over whether the sound from sonar has been causing marine mammals to strand.
Navy officials said that a review of the July 3 incident indicates that two ships turned on their sonar between 6:45 and 7:10 a.m., by most accounts just before the unusual movement of almost 200 deep-water whales to the shoreline of a Kauai bay. The Navy had said earlier that no sonar was used until more than 90 minutes later, well after the animals came ashore.
Lieutenant Commander Greg Geisen, the Navy spokesman responsible for information about the maneuver, said a Navy review of the incident still concluded that the ships were either too far from the whales or were using the sonar at the wrong time to cause the mass movement.
"There is no evidence of a relationship here between the sonar use and the whale behavior," he said.
But the newly released information from Geisen and other Navy officials -- that the ships were testing their sonar in preparation for the maneuver on the day before the whales came ashore, and early on the morning of the near-stranding -- has caused some observers to question that conclusion.
