Real-time reporting of baleen whale passive acoustic detections from ocean gliders
(Acoustical Society of America, 2013-08)
In the past decade, much progress has been made in real-time passive acoustic monitoring of marine mammal occurrence and distribution from autonomous platforms (e.g., gliders, floats, buoys), but current systems focus ...
Passive acoustic detection of deep-diving beaked whales
(Acoustical Society of America, 2008-11)
Beaked whales can remain submerged for an hour or more and are difficult to sight when they come to the surface to breathe. Passive acoustic detection (PAD) not only complements traditional visual-based methods for detecting ...
Low complexity lossless compression of underwater sound recordings
(Acoustical Society of America, 2013-03)
Autonomous listening devices are increasingly used to study vocal aquatic animals, and there is a constant need to record longer or with greater bandwidth, requiring efficient use of memory and battery power. Real-time ...
Three-dimensional beam pattern of regular sperm whale clicks confirms bent-horn hypothesis
(Acoustical Society of America, 2005-03)
The three-dimensional beam pattern of a sperm whale (Physeter macrocephalus) tagged in the Ligurian Sea was derived using data on regular clicks from the tag and from hydrophones towed behind a ship circling the tagged ...
Off-axis effects on the multipulse structure of sperm whale usual clicks with implications for sound production
(Acoustical Society of America, 2005-11)
Sperm whales (Physeter macrocephalus) produce multipulsed clicks with their hypertrophied nasal complex. The currently accepted view of the sound generation process is based on the click structure measured directly in front ...
