We explore the utility of estimating the density of calls of baleen whales for better understanding acoustic trends over time. We consider as a case study stereotyped 'song' calls of Antarctic blue whales (Balaenoptera musculus intermedia)…
Meridional winds over the seasonal ice zone of the Antarctic have undergone changes and likely contributed to sea ice extent variability in recent decades. In this study, using observations and an eddy-resolving channel model of the Antarctic seasonal ice zone…
Blue whale populations each produce distinctive repeated songs that are stable over periods of decades, and can be used to identify where each population resides and moves. In the Southern Hemisphere and northern Indian Ocean, there are at least seven distinct populations based on their songs…
Previous underwater recordings made in New Zealand have identified a complex sequence of low frequency sounds that have been attributed to blue whales based on similarity to blue whale songs in other areas.
Marine bioacoustics research in Australian waters has developed for more than 30 years, and has revealed a wide diversity of … sounds and acoustic environments. The number of researchers and the complexity of the experiments has increased over the years.
This short paper describes 3 consistent regional differences in fin whale vocalizations recorded in the Southern … Ocean. Long term recordings were analysed from locations in eastern and western Australia, and locations south of … these in the Antarctic.
Remote acoustic moorings can be used to investigate baleen whales at vastly different temporal and spatial scales. On one end of the spectrum…
