FIG. 1.

Spectrograms are shown for an example in each call category: (a) multi-part frequency stepping tonals, (b) upsweep, (c) tonal, (d) downsweep, (e) upsweep stepping up, and (f) a series of three broadband calls. All spectrograms were made with a FFT length of , 95% overlap, and a Hanning window.

A cluster of sei whale calls is illustrated, starting with two broadband calls at 2 and , followed by a five component call starting at , a broken or two part downsweep at and a weak downsweep at .

Histograms of the (a) duration and (b) frequency of the 94 tonal call components from the 50 tonal calls.

The open squares indicate the locations of tonal and sweep calls, while the open circles indicate the location of broadband type calls. The plus symbols indicate the ship track at intervals and the filled circles indicate the sonobuoy locations.
