Understanding the impacts of anthropogenic sound on beaked whales

open access: yesJ. Cetacean Res. Manage., 2023
This review considers the effect of anthropogenic sound on beaked whales2. Two major conclusions are presented: (1) gas-bubble disease, induced in supersaturated tissue by a behavioural response to acoustic exposure, is a plausible pathologic mechanism ...

Evaluation of nutritive condition and reproductive status of migrating gray whales (Eschrichtius robustus) based on analysis of photogrammetric data

open access: yesJ. Cetacean Res. Manage., 2023
Vertical aerial photographs were collected of gray whales migrating along the California Coast between 1994 and 1998 to readdress some published findings on the biology and life history of this population based on examination of specimens. For each whale,

Vocalisations of Antarctic blue whales, Balaenoptera musculus intermedia, recorded during the 2001/2002 and 2002/2003 IWC/SOWER circumpolar cruises, Area V, Antarctica

open access: yesJ. Cetacean Res. Manage., 2023
Blue whale vocalisations recorded during the 2001/2002 and 2002/2003 International Whaling Commission-Southern Ocean Whale and Ecosystem Research (IWC/SOWER) cruises were analysed to determine the feasibility of using acoustic recordings for sub-species ...

Abundance, range and movements of a feeding aggregation of gray whales (Eschrichtius robustus) from California to southeastern Alaska in 1998

open access: yesJ. Cetacean Res. Manage., 2023
This study documents the range, abundance and movements of a feeding aggregation of gray whales (Eschrichtius robustus) in the Pacific northwest. Identification photographs were collected by eight collaborating organisations between March and November ...

Behavioural responses of humpback whales (Megaptera novaeangliae) to whalewatching boats near Isla de la Plata, Machalilla National Park, Ecuador

open access: yesJ. Cetacean Res. Manage., 2023
Machalilla National Park, on the coast of mainland Ecuador, supports a growing whalewatching industry that focuses on Southern Hemisphere humpback whales, which spend the austral winter (June-September) in this area.

Behavioural responses of male killer whales to a ‘leapfrogging’ vessel

open access: yesJ. Cetacean Res. Manage., 2023
The research and whalewatching communities of Johnstone Strait, British Columbia, Canada have worked closely together to identify whalewatching practices that minimise disturbance to northern resident killer whales.

Eavesdropping at the Speed of Light: Distributed Acoustic Sensing of Baleen Whales in the Arctic

open access: yesFrontiers in Marine Science, 2022
In a post-industrial whaling world, flagship and charismatic baleen whale species are indicators of the health of our oceans. However, traditional monitoring methods provide spatially and temporally undersampled data to evaluate and mitigate the impacts ...

Fear of Killer Whales Drives Extreme Synchrony in Deep Diving Beaked Whales

open access: yesScientific Reports, 2020
Fear of predation can induce profound changes in the behaviour and physiology of prey species even if predator encounters are infrequent. For echolocating toothed whales, the use of sound to forage exposes them to detection by eavesdropping predators ...
