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

The detection of tracks in spectrograms is an important step in remote sensing applications
such as the analysis of marine mammal calls and remote sensing data in underwater …

Passive acoustic monitoring allows the assessment of marine mammal occurrence and
distribution at greater temporal and spatial scales than is now possible with traditional visual …

Methods for the fully automatic detection and species classification of odontocete whistles
are described. The detector applies a number of noise cancellation techniques to a …

Passive acoustic observation of whales is an increasingly important tool for whale research.

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 …

Passive acoustics provides a powerful tool for monitoring the endangered North Atlantic
right whale (Eubalaena glacialis), but robust detection algorithms are needed to handle …

An algorithm is presented for the detection of frequency contour sounds—whistles of
dolphins and many other odontocetes, moans of baleen whales, chirps of birds, and …
