From: Killer whale call detection rates vary among subspecies and populations in the North Pacific
Gulf of Alaska and AT1 transient killer whale discrete call detection rates. Call detection rates are shown by each potential explanatory variable: (A) hydrophone location, (B) time of day (day or night), (C) mean signal-to-noise ratio, and (D) day of year. In (A) and (B), 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 (C) and (D), each point represents a recording. Gulf of Alaska transients were not acoustically detected in Resurrection Bay during the study period; AT1 transients were not detected in Kachemak Bay during the study period. Overlapping observations appear darker in color. Call detection rate with time as calling period is shown.
