Judge Imposes Stricter Rules on Navy to Protect Marine Life

SAN FRANCISCO — A federal judge has ordered the Navy to adopt stringent new safeguards intended to improve protection of whales and dolphins during its sonar training exercises off Southern California.

The ruling, issued Thursday by Judge Florence-Marie Cooper of the United States District Court for the Central District of California, orders the Navy to limit its use of medium-range sonar to an area beyond 12 nautical miles from shore. Closer to the shore, marine mammals have exhibited frenzied and disoriented behavior during the emissions of sonar blasts as part of the Navy’s practice missions.

Judge Cooper’s order also outlined safeguards, which include a monitoring session one hour before a military exercise to detect the presence of marine mammals, the use of trained aerial lookouts throughout exercises and a mandatory sonar shutdown when mammals are spotted within 2,200 yards of training maneuvers.

The ruling stems from a long-running legal battle between environmental groups, led by the Natural Resources Defense Council, and the Navy, which has argued that mid-frequency sonar is vital to the training of submarine seamen and other crews who now face a new generation of quiet submarines that cannot be detected by traditional passive sonar waves.
