Vocalisations of Antarctic blue whales, Balaenoptera musculus intermedia, recorded during the 2001/2002 and 2002/2003 IWC/SOWER circumpolar cruises, Area V, Antarctica / Shannon Rankin, Don Ljungblad, Chris Clark, Hidehiro Kato.

Abstract: Presents analysis of vocalisation recordings made in Australian and Pacific sectors of Southern Ocean. Relatively short-duration frequency-modulated sounds were similar to vocalisations recorded in presence of blue whales worldwide, and not all recordings contained long-duration 28Hz tonal sounds considered species-specific vocalisation of Antarctic blue whales. Long-duration 28Hz tonal vocalisations included 3-unit calls considered song phrases, as well as simple 28Hz sounds and 28Hz sounds followed by downsweep. Centre and peak frequencies of 28Hz tone for all three sound types were stable regardless of signal strength, but presence and characteristics of 2nd and 3rd units of 3-unit vocalisations were variable. Examination of two distinct groups of simultaneously vocalising blue whales showed no evidence of temporally repeated patterns of song-phrase vocalisations. Results suggest that peak frequency of 28Hz vocalisations may be used as diagnostic feature to aid in discriminating between Antarctic blue whales and pygmy blue whales in the field.
