Blainville’s beaked whale (Mesoplodon densirostris) echolocation clicks from autonomous passive acoustic recordings ...
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 dat...
