Abstract

During a recent cetacean survey of the U.S. waters surrounding the Hawaiian Islands, the probable
source of the mysterious “boing” sound of the North Pacific Ocean was identified as a minke whale,
Balaenoptera acutorostrata. Examination of boing vocalizations from three research surveys
confirms previous work that identified two distinct boing vocalization types in the North Pacific. The
eastern boing (n=22) has a pulse repetition rate of 92 s−1 and a duration of 3.6 s and was found only
east of 138°W. The central boing (n=106) has a pulse repetition rate of 115 s−1 and a duration of
approximately 2.6 s and was found only west of 135°W. Central boing vocalizations produced by
a single source (n=84) indicate that variation in repetition rate and duration of the calls of the
individual were not significantly different than the variation among individuals of the same boing
type. Despite a slight latitudinal overlap in the vocalizations, pulse repetition rates of the eastern and
central boings were distinct.
