They've also got an old standby: the net. The 30-ton mammal was in Delaware Bay at Ship John Shoal, about 50 miles south of Philadelphia and just 25 miles from the Atlantic and a plentiful food supply of plankton. "Every inch closer it gets to the sea, the better off it is," said Charles Mayo, a marine biologist from the Center for Coastal Studies in Provincetown, Mass. The young whale got lost a week ago during its winter migration to Florida when it turned north at the bay and ended up on the Philadelphia waterfront. Probably confused by the fresh water, the whale has repeatedly changed its course, swimming as far north as Rancocas Creek in Burlington County, N.J., and as far south as Wilmington, Del. Scientists put a tiny VHF radio tag on the whale's back Friday, allowing them to track it from the air. They had used underwater speakers blasting the sound of killer whales to steer the whale right. It didn't work. So they set up a 250-foot line of underwater speakers in the Delaware River to emit high-pitched frequencies to scare the whale back toward the Atlantic if it returns northward. "They create quite a messy sound underwater, especially for an animal accustomed to acoustic guides," said Scott Kraus, a right whale expert from the New England Aquarium in Boston. "This would be our last line of defense before we consider a capture." That would involve a 60-foot long, 25-foot wide rectangular nylon net constructed by a team of Navy SEALs and salvage divers from Norfolk, Va. The 29-foot whale would be dragged by up to four boats. Northern rights are the rarest of all the great whales. Once considered a favorite of hunters for their valuable oil, they are typically found off the coast of Cape Cod and Nova Scotia.
