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. Data files are saved as –v7.3 in Matlab 2021a. This file type can be opened via NetCDF routines.

They were analyzed to extract Blainville's beaked whale echolocation clicks. Files are named according to the ...
