Odontocete Spatial Patterns and Temporal Drivers of Detection at Sites in the Hawaiian Islands

January 06, 2023

We conclude that long-term passive acoustic monitoring (PAM records) are a valuable resource for documenting cetacean species patterns and contributes insights into the lives of top predators.

Successful conservation and management of marine top predators rely on detailed documentation of behavior. For cetacean species, this information is key to defining stocks, habitat use, and mitigating harmful interactions. Research focused on this goal is employing methods such as visual observations, tag data, and passive acoustic monitoring (PAM) data. However, many studies are temporally limited or focus on only one or few species. In this study, we make use of an existing long-term (2009–2019), labeled PAM data set to examine patterning of at least 10 odontocete (toothed whale) species in the Hawaiian Islands using compositional analyses and modeling techniques.
