Abstract:

A study of the behavioral, physical, and acoustic characteristics of humpback whales was conducted at Argus Island Tower near Bermuda during April 1968. Swimming and diving habits were observed and photographed, and underwater sounds produced by the whales were recorded. Whale behavior at the surface prior to diving varied according to the time span of the succeeding dives. Information concerning the range of variation in physical appearance was sufficient to improve the quality of current visual identification aids. Preliminary analysis of humpback sounds indicates components at frequencies as high as 8kHz. Author
