Data on echolocation of Blainville's beaked whale recorded at AUTEC during a 6-day period in spring 2005. more

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. Each record represents a click detection on a seafloor array hydrophone from a single tagged whale. The click association to the DTAG click is available at Automated and manually verified click detections from 82 seafloor hydrophones in a related dataset are available at Original data can be downloaded at under Case Study 3: Beaked whale data. Time zone is GMT. Data type = accoustic call Dataset credit = Density Estimation of Cetaceans from passive Acoustic Fixed sensors (DECAF) (
