Study investigates blue whale vocalization detection ranges in marine environments, suggesting deeper insights into cetacean distribution.
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.
