Estimating beaked whale density from passive acoustic recordings
Abstract
The goals of the project are to obtain key parameters required for acoustic density estimation of beaked whales, and to use these to calibrate and improve the accuracy of density estimators using acoustic data, here in combination with an excellent visual ground-truth. To this end we propose to analyze the existing NOPP dataset of DTAG, drifting acoustic recorders and visual data from El Hierro, and augment this dataset with double-platform visual and acoustic surveys, in the same area. The results wil be direclty applicable to improve the accuracy of methods currently under development to estimate beaked whale density in passive acoustic surveys. The analyses will also provide much needed basic statistics on the acoustic detectability of individual beaked whales and how this changes with group size.
