US Supreme Court Allows Sonar Use
gollum123 writes "The US Supreme Court has removed restrictions on the Navy's use of sonar in training exercises near California. The ruling is a defeat for environmental groups who say the sonar can kill whales and other mammals. In its 5-4 ruling, the Supreme Court said the Navy needed to conduct realistic training exercises to respond to potential threats. The court did not deal with the merits of the claims put forward by the environmental groups. In reinstating the use of sonar, the top US court rejected a lower federal judge's injunction that had required the US Navy to take various precautions during submarine-hunting exercises. The Bush administration argued that there is little evidence of harm to marine life in more than 40 years of exercises off the California coast. It said that the judges should have deferred to the judgment of the Navy and Mr Bush. Writing for the majority, Chief Justice John Roberts said overall public interest was 'strongly in favor of the Navy.' 'The most serious possible injury would be harm to an unknown number of the marine mammals,' Chief Justice Roberts wrote. 'In contrast, forcing the Navy to deploy an inadequately trained anti-submarine force jeopardizes the safety of the fleet.'"
Thats why they put microphones in the water with a marine biologist listening constantly during testing and another on the bridge with binoculars looking for whales. Its why they observe a half hour before starting a sequence as standard procedure to make sure there are no marine mammals. They do what has to be done to ensure that there is nothing that can be harmed by the sonar in the vicinity.
I routinely spend large amounts of time at sea for the US Navy. The ship I am on doesn't have active sonar, but:
- We have a OS(W)or AB(W) topside at all times watching when we are underway watching for whales. The whale has the right of way.
- We're not allowed to intentionally encroach within 1km to a whale. Dolphins and similar are fast moving/smart enough to think we might eat them. Most whales appear to think we are a really big whale and seem to like coming over to visit.
- If our direction of travel is blocked by a whale, we must either steer to avoid or perform a rather unloved manuveur known as a 'crash stop'.
- If we are operating with another ship we must abort operations if a whale enters the area.
