Description:
Humpback whales produce a very wide variety of sounds while
on thier feeding grounds in the waters of Alaska. Moans, grunts,
pulse trains (Thompson et al. 1986) and long, complex songs
(McSweeney et al. 1989) have been recorded in these waters.
These sounds were recorded in the winter of 1999 and include
both upsweeping and downsweeping moans.
