METHODS Fixed passive acoustic surveys require several steps, including survey design,
placement and sometimes recovery of recording instruments, extraction of vocalizations of …

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

Acoustic data provide scientific and engineering insights in fields ranging from biology and
communications to ocean and Earth science. We survey the recent advances and …

Traditionally, animal species diversity and abundance is assessed using a variety of
methods that are generally costly, limited in space and time, and most importantly, they …

Cetacean–habitat modeling, although still in the early stages of development, represents a
potentially powerful tool for predicting cetacean distributions and understanding the …

Delphinid communication has been shaped by the marine environment. This resulted in
specific adaptations such as echolocation and a sophisticated communication system that …

The spectral and temporal properties of echolocation clicks and the use of clicks for species
classification are investigated for five species of free-ranging dolphins found offshore of …

The ability to identify delphinid vocalizations to species in real-time would be an asset
during shipboard surveys. An automated system, Real-time Odontocete Call Classification …

Deep neural networks have advanced the field of detection and classification and allowed
for effective identification of signals in challenging data sets. Numerous time-critical …

A disparate selection of toothed whales (Odontoceti) share striking features of their acoustic
repertoires including the absence of whistles and high frequency but weak (low peak‐to …
