Anatomy of a "Boing"
(NOTE:This video contains audio)
The “boing” sound was first heard by U.S. Navy submarines in the 1950s off San Diego, California, and Kaneohe, Hawaii. Despite much attention, the source of the sound has remained a mystery until recently. On November 7, 2002, the Southwest Fisheries Science Center (SWFSC) acoustics team located the source of a series of boing sounds in the open ocean offshore the Hawaiian Islands. They directed the ship to this location, allowing experienced marine mammal observers to identify the source of the "boing" sound as a minke whale.
