Earth Changes
No, wait, it's Earth's magnetic field, another caller told the University of Illinois professor.
Most days, the research biologist studies orcas from the Center for Whale Research in Friday Harbor, Washington, and from his home porch perched above Puget Sound, where the animals hunt and play in summer months.
But one day last May, Balcomb and whale-watchers along the coast observed something they had never seen before. "I first heard reports from whale-watchers that orcas where behaving very unusually," Balcomb recalled. "One pod had gathered in a tight group and were moving close to shore."
Balcomb confirmed at the time that strange underwater pinging noises detected with underwater microphones were sonar. The sound originated from a U.S. Navy frigate 12 miles (19 kilometers) distant, Balcomb said. The vessel eventually moved within 4 miles (6.4 kilometers) of Puget Sound.
When the killer whales of Washington State's Puget Sound began vanishing, a biologist had to get an earful from the U.S. Navy to pick up clues to the mystery (Washington map).
Using supersensitive microphones, Ken Balcomb has been eavesdropping on the region's resident killer whales, also known as orcas. Unlike their transient brethren, these animals spend their entire lives in the sound.
But Balcomb's years of research unveiled a disturbing trend: Mature orcas were disappearing in the prime of their lives, and no one knew why.
The National Weather Service said Sunday that more than a dozen new tornadoes have been reported in the area where the tornado caused its heavy damage Friday.
The National Weather Service's Riverton office reported that a foot of snow had fallen on Casper Mountain as of 5 p.m., and that similar amounts had fallen in lower elevations in the city.
That obliterated a record set on May 5, 1971, when the previous record -- one inch -- fell on the city.
