Many marine animals use sound passively or actively for communication, foraging, predator
avoidance, navigation, and to sense their environment. The advent of acoustic recording …

Machine learning has been advancing dramatically over the past decade. Most strides are
human-based applications due to the availability of large-scale datasets; however …

Beaked whale echolocation signals are mostly frequency-modulated (FM) upsweep pulses
and appear to be species specific. Evolutionary processes of niche separation may have …

Machine learning algorithms, including recent advances in deep learning, are promising for
tools for detection and classification of broadband high frequency signals in passive …

This study presents a system for classifying echolocation clicks of six species of odontocetes
in the Southern California Bight: Visually confirmed bottlenose dolphins, short-and long …

Mid-frequency active sonar (MFAS), used for antisubmarine warfare (ASW), has been
associated with multiple beaked whale (BW) mass stranding events. Multinational naval …

Fear of predation can have wide-ranging ecological effects. 1–4 This is especially true in the
ocean's pelagic zone, the Earth's largest habitat, where vertical gradients in light and …

The Indian Ocean and Atlantic bottlenose dolphins (Tursiops aduncus and Tursiops
truncatus) are among the best studied echolocating toothed whales. However, almost all …

The study of marine soundscapes is a growing field of research. Recording hardware is
becoming more accessible; there are a number of off-the-shelf autonomous recorders that …

Passive acoustic monitoring (PAM) is increasingly being adopted as a non-invasive method
for the assessment of ocean ecological dynamics. PAM is an important sampling approach …
