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

Defining the appropriate scale over which to conduct a study in the marine environment is
critical to achieving appropriate scientific, management, mitigation and conservation …

Ocean currents, winds, and rainfall all work together to create a marine oasis around the
Hawaiian Islands, providing a home for many species of dolphins and whales normally …

Passive acoustic monitoring (PAM) is a rapidly growing field, providing valuable insights in
marine ecology. The approach allows for long-term, species-specific monitoring over a …

Minke whales comprise some of the most widely distributed species of baleen whales, some

Abstract The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is an
endangered freshwater porpoise subspecies unique to the Yangtze River basin. Seasonal …

Density estimation for marine mammal species is performed primarily using visual distance
sampling or capture‐recapture. Minke whales in Hawaiian waters are very difficult to sight; …

Estimation of cetacean abundance or density using visual methods can be cost-ineffective
under many scenarios. Methods based on acoustic data have recently been proposed as an …

Although white sharks (Carcharodon carcharias) have been considered rare in Atlantic
Canada waters, recent sighting records indicate a potentially increasing presence. We …

Yangtze finless porpoises were surveyed by using simultaneous visual and acoustical
methods from 6 November to 13 December 2006. Two research vessels towed stereo …
