|Atlantic fin whale call|
The 20-Hz signals of finback whales are perhaps one of the better
described whale calls in the Atlantic Ocean. Typically, these
signals are short (< 1s) pulses that downsweep from about
23 Hz to 18 Hz. These pulses typically are produced in groups
or "bouts"(Watkins et al. 1987). Pulse duration, frequency
and bout length can vary with location.
