Examples of killer whale (Orcinus orca) calls from passive acoustic monitoring in the Gulf of Alaska

Three killer whale (Orcinus orca) ecotypes are found in the northeastern Pacific: residents, transients, and offshores. Each ecotype produces distinct, stereotypic pulsed calls that serve as acoustic indicators of presence. To investigate the spatial and temporal occurrence of each ecotype in the Gulf of Alaska, long-term acoustic recorders were intermittently deployed from 2011 to 2019 at seven sites along the continental shelf and slope, in an abyssal region, and near offshore seamounts. This dataset contains examples of killer whale calls from these recordings. The examples are grouped based on the results of ecotype discrimination using established catalogs of call repertoires for each ecotype.
