Original provider: Density Estimation of Cetaceans from passive Acoustic Fixed sensors (DECAF) Abstract: This archive contains data on echolocation clicks of Blainville's beaked whale (Mesoplodon densirostris) recorded at AUTEC during a 6-day period in spring 2005. The data were used in estimating M. densirostris density as documented in the paper Marques et al. (2009). There are data files containing click counts per minute per hydrophone, files containing numbers of false positive detections from a manual analysis, and files giving information about georeferenced tracks of tagged whales and associated vocalization timings.
