Blainville's beaked whale (Mesoplodon densirostris) echolocation clicks from autonomous passive acoustic recordings

Description
Understanding the distribution of cetacean species and their populations over space and time is relevant to conservation, management, and mitigation goals. Geographic differences in acoustic signals may provide a line of evidence for population-level discrimination in some cetacean species. This data set of acoustic recordings collected over broad spatial and temporal scales was used to investigate whether global variability in echolocation click peak frequency could elucidate population structure in Blainville's beaked whale (Mesoplodon densirostris). It consists of ~4.1M event detections from over 70 instrument deployments at 23 sites.
