Abstract

An acoustic record from Cross Seamount, southwest of Hawaii, revealed sounds characteristic of beaked whale echolocation at the same relative abundance year-around !270 of 356 days", occurring almost entirely at night. The most common sound had a linear frequency upsweep from 35 to 100 kHz !the bandwidth of recording", an interpulse interval of 0.11 s, and duration of at least 932 !s. A less common upsweep sound with shorter interpulse interval and slower sweep rate was also present. Sounds matching Cuvier’s beaked whale were not detected, and Blainville’s beaked whale sounds were detected on only one occasion.
