Low-frequency sonar killed whales, U.S. Navy and NMFS admit
From ANIMAL PEOPLE, January/February 2002:
WASHINGTON, D.C.–A joint report by the U.S. Navy and
National Marine Fisheries Service confirms the February 2001
allegation of Center for Whale Research founder Ken Balcomb that
sound waves from Navy sonar exercises caused 16 small toothed whales
and a spotted dolphin to beach themselves in the Bahamas in mid-March
2000.
Seven of the animals died. The other 10 were pushed back out
to sea by would-be rescuers, but are also believed to have died.
