Description:
Calls of blue whales (Balaenoptera musculus), fin whales (Balaenoptera physalus), and humpback whales (Megaptera
novaeangliae) were identified in the data from U.S. Navy Sound Surveilance System (SOSUS) and other hydrophone arrays.
These data on calling whales from November 1995 through July 1999 have been listed here for four offshore, deep-water Regions
along continental margins of the North and Northeast Pacific. The occurrence of calling whales was monitored during two-day
periods each week. Call data recorded from each array identified species, call occurrence, variation, received beam, and relative
numbers of calling whales. This allowed assessment of seasonal distribution of calls for the different species, and provided
locations for sources received at multiple arrays. Blue whale tonal sounds were distributed widely, received most in the NW
Region, with a peak in occurrence in the fall. Fin whale "20-Hz" repetitive pulse sequences were received from whales grouped in
local areas in all Regions, with a peak in occurrence in midwinter. Humpback songs were received from December through May
particularly in the SE Region. The offshore listening systems allowed basin-wide monitoring of the seasonal distribution of these
callng whales.
