This seventh year of monitoring calling whales via SOSUS hydrophones has continued to provide good data on the seasonal distribution blue, fin and humpback whales across the North Pacific. These data have allowed assessment of annual movements, environmental variability, and changes in call features. These data demonstrate 1 the occurrence and movements of calling components of the populations of these species in the offshore waters across the North Pacific, 2 the changes in these calls, 3 the estimated numbers of calling whales, 3 the correlation of calling with known features of population activities, 4 the annual patterns of offshore whale calling, and 5 tracks for individual whales. These have allowed good forecasts for the occurrence of these strong biological noises.
