Fin whale (Balaenoptera physalus), recording 2
Jan 13, 2023, 11:25 AM
Fin whales produce a variety of short low frequency calls, of which the 20 Hz pulse is most prominent (i.e., a downsweep ranging from around 30-15 Hz) and produced by fin whales worldwide. We record this call most frequently in the vicinity of Elephant Island, off the northern tip of the Antarctic Peninsula, where the 20 Hz pulse also often contains a higher frequency component around 89 Hz.
