Environmentalists argue that mid-frequency active sonar can disrupt whale feeding patterns, and in the most extreme cases can kill whales by causing them to beach themselves. But scientists aren't sure why sonar affects some species more than others. They also don't fully know how it hurts whales. The Navy acknowledges sonar may harm marine mammals but says it takes steps to protect whales. It says more research needs to be done to better understand how sonar affects whales before it adopts additional protective measures. The Pacific Fleet has made anti-submarine warfare a top priority as more countries, including North Korea, Iran, and China, have been acquiring quiet diesel-electric submarines that are increasingly difficult to track. The Navy said the settlement, which was reached Friday, calls on it to spend $14.75 million over three years on marine mammal research topics of interest to both the Navy and the plaintiffs. The Navy said the long-range research program it adopted under the settlement is basically the same as the one it set out to follow in August 2005, two months before the lawsuit was filed. Other plaintiffs were: International Fund for Animal Welfare, Cetacean Society International, League for Coastal Protection, Ocean Futures Society and Jean-Michel Cousteau.
