Navy Ordered to Establish Sonar-free Zones

(02-06) 19:27 PST San Francisco — For the second time this week, a federal court found today that a Navy anti-submarine training program threatened to subject whales and other sea creatures to harmful blasts of sonar and ordered protective measures in several sensitive zones, including one near Monterey Bay.

The ruling by U.S. Magistrate Elizabeth Laporte of San Francisco applies to the Navy’s use of low-frequency sonar in submarine detection exercises conducted in large areas of the world’s oceans. She said Navy officials, who had agreed to restrictions after she issued a similar ruling in 2002, failed to take adequate precautions when seeking a five-year renewal of the program last year.

In its plans to shut off the sonar when whales and other vulnerable creatures are spotted, the Navy is relying on visual monitoring, which is unreliable, and on sonar detection, which is limited in range and may miss dolphins and other small animals, Laporte said.

“Marine mammals, many of whom depend on sensitive hearing for essential activities like finding food and mates and avoiding predators, will at a minimum be harassed by the extremely loud and far-traveling (low-frequency) sonar,” the magistrate said.

She said the Navy must establish sonar-free zones around several areas where sensitive marine life is plentiful, including the Davidson Seamount, which adjoins the Monterey Bay National Marine Sanctuary; the Galapagos Islands, 0ffshore from Ecuador; the Great Barrier Reef off Australia; the Pelagos, in the Mediterranean Sea, and a protected area of coral reefs and underwater habitat 115 miles northwest of the Hawaiian islands.
