TL;DR: Ratilal et al. as discussed by the authors used a combination of passive and active ocean acoustic waveguide remote sensing in an important northwestern Atlantic marine mammal autumn foraging ground to detect, localize and classify MM vocalizations from diverse species over an approximately 100,000 km2 region.

TL;DR: In this article, a large-aperture densely sampled coherent hydrophone array was deployed in late winter 2014 to monitor their vocalizations instantaneously over wide areas via passive ocean acoustic waveguide remote sensing (POAWRS).

TL;DR: The passive ocean acoustic waveguide remote sensing technique is employed to detect and characterize the underwater sound radiated from three scientific research and fishing vessels received at long ranges on a large-aperture densely-sampled horizontal coherent hydrophone array, which is dominated by distinct narrowband tonals and cyclostationary signals.

TL;DR: Time-frequency characterizations of the underwater sounds radiated from the commercial ships and the unidentified vessels are provided and the time-frequency features along with the bearing-time trajectory of the detected signals are applied to simultaneously track and distinguish these vessels.

TL;DR: The source level distributions and pulse compression gains are essential for determining signal-to-noise ratios and hence detection regions for baleen whale vocalizations received passively on underwater acoustic sensing systems, as well as for assessing communication ranges in balean whales.
