Dates of acoustic data collection Kenai Shelf: 07/13/2011 to 09/09/2014 Kodiak Shelf: 06/09/2013 to 09/11/2014 Kodiak Slope: 04/24/2019 to 09/27/2019 Kenai Slope: 07/13/2011 to 09/27/2019 Abyssal: 04/29/2017 to 09/13/2017 Quinn: 06/10/2013 to 09/13/2017 Pratt: 09/09/2012 to 09/10/2014 4. Geographic locations of acoustic data collection Kenai Shelf: 59° 00.53' N, 148° 54.33' W Kodiak Shelf: 57° 20.11' N, 150° 41.87' W Kodiak Slope: 57° 13.44' N, 150° 31.70' W Kenai Slope: 58° 40.26' N, 148° 01.43' W Abyssal: 57° 30.82' N, 146° 30.05' W Quinn: 56° 20.40' N, 145° 11.16' W Pratt: 56° 14.61' N, 142° 45.44' W 5. Funding sources that supported the data collection: US Pacific Fleet DATA & FILE OVERVIEW 1. Description of dataset The call examples contained in this dataset were used to discriminate between killer whale ecotypes in passive acoustic recordings collected at 7 sites in the Gulf of Alaska. Each compressed zip file contains a folder for the recording sites where examples came from. The site folders contain .wav files of killer whale acoustic encounters and associated .jpg files of the spectrogram. .wav files are typically 30s long and associated .jpg files depict a 30s spectrogram. For longer .wav files, the spectrogram is only of the first 30s of the acoustic encounter. Files are named using abbreviations for sites (Kenai Shelf = CA, Kodiak Shelf = KO, Kodiak Slope = KOA, Kenai Slope = CB, Abyssal = AB, Quinn = QN, and Pratt = PT). Note that there is no associated .jpg for KO02_Enc221_full.wav within the Unknown\Kodiak Shelf folder. A sample of this acoustic encounter is provided by KO02_Enc221.wav and KO02_Enc221.jpg, but we have also provided the full 13.5 min encounter as the calls were very distinct from other encounters in this dataset. 2.
