A 6-minute recording from hydrophone 57 was manually checked for beaked whale clicks. This 6-minute section was part of the main 6-day dataset used in the case study. The automatic detector was used on the same sound file, and the results compared. For each manually detected click, the signal-to-noise ratio (SNR) was calculated, the quality of the click was judged and it was noted whether or not the click was detected by the automatic detector.

Using propagation modelling, information about the source level of the clicks and characteristics of the automatic click detector, the effective detection radius around the hydrophone was estimated. Together with information about clicking rates of beaked whales, this enabled density of beaked whales around the hydrophone to be estimated. notPlanned Elizabeth Kusel Elizabeth Kusel Primary contact kusele@alum.rpi.edu NA NA NA Elizabeth Kusel owner NA zd_720 2025-07-31T15:32:52-04:00 dataset Kusel, E. 2013.
