Killer Whale Sound Production at SanctSoundSite OC02_01

This record represents killer whale sound production. Killer whale calls were detected by analysts and logged using Triton's Logger Remora. Calls were grouped into encounters, with encounters more than 30 min apart being logged as separate encounters. The following settings were used for manual scanning of long-term spectral averages: bandwidth 0-5000 Hz; 1 hour duration; and for zoomed-in scanning of spectrograms: plot length 30 s, FFT length 1000, 90% overlap. Killer whale encounters were further classified into ecotypes based on the presence of ecotype-specific call types in the encounter. Call types were identified in the spectrogram window, and all calls in an encounter were examined before an encounter was attributed to a particular ecotype. Resident ecotype call types were identified from the reference catalogue of Ford 1987, transient ecotype call types were identified from a reference catalogue based on recordings published by Deecke 2003, and offshore ecotype call types were identified from a digital catalogue (J Ford, unpubl. data) collected during field encounters with photo- or genetically identified offshore killer whales.These data were recorded at SanctSound Site OC02_01 between March 08, 2019 and April 24, 2019.
