The United States is facing increasing international pressure to place limitations on the use of military sonar ... that has been linked to mass strandings of whales. The European Union Parliament -- the most prominent of four international bodies that have taken up the matter in recent months -- called in October for its member states to develop a moratorium on all types of military sonars, which use powerful sound to locate objects such as submarines. According to studies cited by the EU and the other world bodies, noise can interfere with the survival of the ocean creatures that depend on sound to navigate, find food, locate mates, avoid predators and communicate with one another. At high decibel levels, noise can kill. The U.S. Navy is the biggest user of midfrequency active sonar in the world -- and government officials have been loath to require permits to regulate its use. In more than a dozen instances dating back to the 1960s, however, whales have stranded themselves on the beaches and sometimes died at the time of naval training exercises miles away using midfrequency active sonar. An unprecedented stranding of 16 beaked and minke whales in the Bahamas in 2000 brought worldwide attention to military sonar. A NOAA investigation concluded that a Navy testing maneuver using midfrequency sonar -- by far the most commonly used type of sonar -- was the likely cause. Necropsies found signs of brain hemorrhaging, which is consistent with injury from sound.

Navy's use of sonar suspected in near-stranding of whales

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. "Every time the Navy changes its story, it reduces its credibility on this issue," said Cara Horowitz, a lawyer with the Natural Resources Defense Council. Residents and government officials worked throughout July 3 to steer the whales back to open water, and all made it except one newborn calf that died of starvation. The Hawaii incident is the third significant one involving sonar and marine mammal strandings near the United States since 2000. The stranding of 17 whales of various kinds off the Bahamas in 2000, which resulted in the death of at least six of them, occurred during a major Navy maneuver. Navy officials at first said there was no connection between their exercise and the stranding, but later acknowledged that the loud sound from the sonar had caused the animals to flee ashore.
