SC/61/SH16 1 Geographic Variation in Southern Ocean Fin Whale Song
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. Preliminary analysis indicates fin whale ‘20Hz pu...

Long term recordings were analysed from locations in eastern and western Australia, and locations south of these in the Antarctic. Preliminary analysis indicates fin whale ‘20Hz pulses ” off Tasmania and south to the Antarctic continent (at ~145°E) had 2 distinctive higher frequency components with peaks at ~82 and ~94Hz, while those off Western Australia and Antarctica (at ~75-80°E) had a single distinct higher frequency component with a peak near ~99Hz.
