Killer Whale Sound Production at SanctSoundSite OC01_03
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 OC01_03
between November 02, 2019 and April 10, 2020.
