- Detection ranges of blue whale vocalizations from a glider-based hydrophone. Gutiérrez, Laura Buchan, Susannah Stafford, Kathleen M Baumgartner, Mark Bedriñana-Romano, Luis Ramirez, Nadin Pizarro, Oscar Animals Vocalization, Animal Balaenoptera Chile Acoustics Sound Spectrography This study investigated the detection range (DR) of blue whale (Balaenoptera musculus sp.) vocalizations (SEP2 and D-calls) in Chilean Patagonia using data collected from ocean glider-based hydrophones. DRs were determined by calculating the figure of merit of each vocalization. SEP2 consistently exhibited a greater DR compared to D-calls across the study area. Glider depth and bathymetry emerged as the most influential factors affecting DR. Taking DR and the factors that influence it into account enables a more robust interpretation of acoustic studies on the spatial distribution of cetaceans.
