Summary of measurements for categorized burst-pulse sounds and remaining groups produced by killer whales recorded in Bremer Canyon, Western Australia.

Number of burst-pulse sounds per group: n. For each group, the range over all of the calls belonging to that group is given. Min f: minimum frequency of the lowest contour; Max f: maximum frequency of the lowest contour; Start f: frequency of where the lowest contour commenced; End f: frequency of where the lowest contour finished; Delta f = Max f − Min f; Duration (s); Number of extrema; Number of inflection points; FM rate = Number of inflections points / duration.* Whistles with pulsed middle section. Min f, Max f, Delta f were measured off the whistle fundamental. Duration, and numbers of extrema and inflection points are for the entire call. Sideband spacing was measured off the pulsed middle section.**Burst-pulse = > whistle transitions and whistle = >burst-pulse transitions. Min f, Max f, Delta f were measured off the whistle fundamental. Duration, and numbers of extrema and inflection points are for the entire call. Sideband spacing was measured off the pulsed section.Summary of measurements for categorized burst-pulse sounds and remaining groups produced by killer whales recorded in Bremer Canyon, Western Australia.
