In the North Pacific, the species is divided into three ecotypes—resident (fish-eating), transient (mammal-eating), and offshore (largely shark-eating)—that are genetically and acoustically distinct and have unique roles in the marine ecosystem. We deployed hydrophones in the northern Gulf of Alaska to examine the year-round distribution of killer whales from 2016 to 2020 using passive acoustic monitoring. Highest year-round acoustic presence occurred in Montague Strait, with strong seasonal patterns in Hinchinbrook Entrance and Resurrection Bay. Passive acoustic monitoring revealed that both resident and transient killer whales used these areas much more extensively than previously known and provided novel insights into high use locations and times for each population. These results may be driven by seasonal foraging opportunities and social factors, and have management implications for this species.Year-round passive acoustic monitoring of killer whalesThis dataset presents killer whale presence or absence based on acoustic detection. The locations of the stationary acoustic devices are approximate. Passive acoustic monitoring efforts were done during the following periods: Montague Strait Hanning Bay 10/1/2016 - 1/31/2017 Little Bay 9/14/2017- 5/7/2018 Little Bay 5/15/2018 - 9/17/2018 Little Bay 10/1/2018 - 9/24/2019 Little Bay 09/27/2019 - 5/31/2020 Hinchinbrook Entrance Port Etches 10/1/2016 - 6/16/2017 Port Etches 9/7/2017 - 5/12/2018 Port Etches 5/15/2018 - 9/30/2018 Zaikof Bay 10/1/2018 - 7/25/2019 Zaikof Bay 10/1/2019 - 5/29/2020 Resurrection Bay 6/7/2018 - 10/2/2018 10/2/2018 - 5/27/2019 5/27/2019 - 9/22/2019 9/22/2019 - 5/31/20202016100120200531ground conditionCompleteNone plannedAlaska-149.6-14760.359.7 NoneMarine Animal SurveyMarine BiologyMarine mammalsAcoustic precense/absenceOcean-based PlatformsNoneAlaskaTaxon coveredMarine mammalsIntegrated Taxonomic Information SystemUnknownNot applicableDownloaded April, 2004http://www.itis.usda.gov/Refer to the contact information of the datasetRefer to the contact information of the datasetmailing and physical address
