Passive acoustic monitoring (PAM) is crucial to expanding the knowledge of beaked whales, including the northern bottlenose whale (Hyperoodon ampullatus) and Sowerby's beaked whale (Mesoplodon bidens). Existing descriptions of clicks produced by these species are limited by sample size, number of individuals recorded, and geographic scope. Data from multiple encounters in the western North Atlantic are used to provide a quantitative description of clicks produced by these species. Recordings…

Specimens of opportunity provide vital information for research and conservation regarding elusive whale species
Snowball sampling was used to identify Sowerby’s beaked whale specimens in museums and research institutions, resulting in the largest collated dataset for this species, suggesting the presence of previously unidentified population structuring in this species.
NOAA and BOEM Minimum Recommendations for Use of Passive Acoustic Listening Systems in Offshore Wind Energy Development Monitoring and Mitigation Programs
Offshore wind energy development is rapidly ramping up in United States (U.S.) waters in order to meet renewable energy goals. With a diverse suite of endangered large whale species and a multitude
Quantitative Soundscape Analysis to Understand Multidimensional Features
A methodology for the analysis of soundscapes was developed in an attempt to facilitate efficient and accurate soundscape comparisons across time and space. The methodology consists of a collection
Identification of western North Atlantic odontocete echolocation click types using machine learning and spatiotemporal correlates
A combination of machine learning and expert analyst review was used to detect odontocete echolocation clicks, identify dominant click types, and classify clicks in 32 years of acoustic data


Patterning in northern bottlenose whale (Hyperoodon ampullatus) click trains
Northern bottlenose whales (Hyperoodon ampullatus ) are large toothed whales of the family Ziphiidae; the beaked whales. They are known to produce various types of click vocalizations including

Sounds produced by northern bottlenose whales (Hyperoodon ampullatm) recorded in the Gully, a submarine canyon off Nova Scotia, consisted predominately of clicks. In 428 min of recordings no whistles
Description of sounds associated with Sowerby's beaked whales (Mesoplodon bidens) in the western North Atlantic Ocean.
The acoustic characteristics of Sowerby's beaked whales have not previously been described; the current study will facilitate incorporation of these data into passive acoustic monitoring programs in the North Atlantic Ocean.
Uncertain status of the northern bottlenose whale Hyperoodon ampullatus: population fragmentation, legacy of whaling and current threats
The northern bottlenose whale Hyperoodon ampullatus is the best-known beaked whale species, but its conservation status remains very uncertain. A medium-sized cetacean that lives in the deeper waters
A description of echolocation clicks recorded in the presence of True's beaked whale (Mesoplodon mirus).
The spectra and measurements of the recorded clicks closely resemble Gervais's beaked whale clicks (Mesoplodon europaeus) and distinguishing between the two species in acoustic data sets proves difficult.
Foraging Blainville's beaked whales (Mesoplodon densirostris) produce distinct click types matched to different phases of echolocation
Blainville's beaked whales (Mesoplodon densirostris Blainville) echolocate for prey during deep foraging dives using acoustic tags to demonstrate that these whales produce two distinct types of click sounds during different phases in biosonar-based foraging.
Analysis of Northern bottlenose whale pulses and associated reflections recorded from the Gully Marine Protected Area
The Gully Marine Protected Area (MPA) is a large submarine canyon at the edge of the Scotian Shelf, south of Nova Scotia. A resident population of northern bottlenose whales are known to occur in the
First indications that northern bottlenose whales are sensitive to behavioural disturbance from anthropogenic noise
High sensitivity of northern bottlenose whales to acoustic disturbance, with consequent risk from marine industrialization and naval activity, is indicated.
Beaked whales echolocate on prey
Beaked whales (Cetacea: Ziphiidea) of the genera Ziphius and Mesoplodon are so difficult to study that they are mostly known from strandings. How these elusive toothed whales use and react to sound
Biosonar performance of foraging beaked whales (Mesoplodon densirostris)
It is suggested that stable ICIs in the search and approach phases facilitate auditory scene analysis in a complex multi-target environment, and that a concomitant low click rate allows the whales to maintain high sound pressure outputs for prey detection and discrimination with a pneumatically driven, bi-modal sound generator.
