Vessel noise affects beaked whale behavior : Results of a dedicated acoustic response study
(2012-08-03) - Journal article
Some beaked whale species are susceptible to the detrimental effects of anthropogenic noise. Most studies have concentrated on the effects of military sonar, but other forms of acoustic disturbance (e.g. shipping noise) ...
Spatio-temporal variation in click production rates of beaked whales : implications for passive acoustic density estimation
(2017-03) - Journal article
Passive acoustic monitoring has become an increasingly prevalent tool for estimating density of marine mammals, such as beaked whales, which vocalize often but are difficult to survey visually. Counts of acoustic cues ...
A simulation approach to assessing environmental risk of sound exposure to marine mammals
(2017-04) - Journal article
Intense underwater sounds caused by military sonar, seismic surveys, and pile driving can harm acoustically sensitive marine mammals. Many jurisdictions require such activities to undergo marine mammal impact assessments ...
Assigning stranded bottlenose dolphins to source stocks using stable isotope ratios following the Deepwater Horizon oil spill
(2017-01-31) - Journal article
The potential for stranded dolphins to serve as a tool for monitoring free-ranging populations would be enhanced if their stocks of origin were known. We used stable isotopes of carbon, nitrogen, and sulfur from skin to ...
An analysis of pilot whale vocalization activity using hidden Markov models
(2017-01) - Journal article
Vocalizations of cetaceans form a key component of their social interactions. Such vocalization activity is driven by the behavioral states of the whales, which are not directly observable, so that latent-state models are ...
Delphinid echolocation click detection probability on near-seafloor sensors
(2016-09) - Journal article
The probability of detecting echolocating delphinids on a near-seafloor sensor was estimated using two Monte Carlo simulation methods. One method estimated the probability of detecting a single click (cue counting); the ...
