Summary edit
DescriptionAk52 10x.ogg |
English: 52 Hz "whale-like" signals were first reported by Watkins et al.(2000). On average these tones had a center frequency of 51.75 Hz and lasted 5-7 sec. These tones are usually produced in groups of 2-6 and were recorded in the NE Pacific. The recorded signal has been sped up 10 times in order to move the sound into the audible range. |
