This study marks the first acoustic comparison between wild belugas and narwhals from the same location and provides strong support for the use of echolocation in PAM efforts to differentiate belugas and narwhals acoustically.
A model-based localization approach is applied to account for errors not typically accounted for by the standard method of passive acoustic monitoring when conducting line-transect cetacean abundance surveys.
This case study illustrates use of a suite of routines designed to efficiently detect cetacean sounds, extract features, and classify the detection to species using ship-based, visually verified detections of false killer whales.
