Acoustic Ecology of Minke Whales.
Abstract
Calls of minke whales, Balaenoptera acutorostrata, off the coast of NE Australia in July of 1997 were recorded utilizing a newly described population, where minke whales maintain long contacts with vessels. Recordings were made in the presence of minke whales aboard the vessel "Undersea Explorer" using a calibrated, two dimensional hydrophone array. Over four-weeks, we encountered 61 minke whales and had extended (up to 11 hours/encounter), close contacts occurring with the majority. We recorded over 21 hours in the direct presence of at least 45 animals. The high density of inquisitive minke whales at the Great Barrier Reef offers an unique opportunity to study their acoustic ecology.
