From: Killer whale call detection rates vary among subspecies and populations in the North Pacific
Southern Alaska resident killer whale call detection rates from autonomous recordings. Call detection rates are shown by each potential explanatory variable: (A) AD16 or AD8 pod, (B) hydrophone location, (C) acoustic presence of other pods in the recording, (D) day of year, (E) time of day (day or night), and (F) mean signal-to-noise ratio across all calls in a recording. In (A), (B), (C), and (E), the horizontal line represents median call detection rate and boxes show the interquartile range. Whiskers extend up to 1.5 times the interquartile range, observations beyond the whiskers are shown as individual points. In (D) and (F), each point represents a four- or five-min recording. Overlapping observations appear darker in color. Call detection rate with time as calling period is shown.
