Acoustically Derived Estimate of the Size Distribution for a Sample of Sperm Whales ( Physeter catodon) in the Western North Atlantic
Acoustic determination of sperm whale length based on measurement of the interpulse interval (IPI) of the characteristic multipulse sound click was used on a sample of 4000 clicks in 193 click series recorded in the North Atlantic. The analysis of IPI could be done with reasonable reproducibility us...
