Canada's Department of National Defence (
http://www.forces.gc.ca/site/index.html) agency is testing a new aquatic robot meant to help locate and protect whales.
The Slocum Diver (
http://www.webbresearch.com/slocum.htm) is a 114-lb. torpedo-shaped vehicle that's five feet long and 8.4 inches in diameter. It can quietly sink into the water to monitor for sounds -- including the high-frequency pitch of whale calls. By deploying the robots, Canadian warships and other craft can mark the positions of whales and avoid them without the whales realizing that they are being tracked.
