The east coast of Scotland bottlenose dolphin population : improving understanding of ecology outside the Moray Firth SAC
(Department of Energy and Climate Change, 2014-05-07) - Report,
The significance of respiration timing in the energetics estimates of free-ranging killer whales (Orcinus orca)
(2016-07) - Journal article,
Respiration rate has been used as an indicator of metabolic rates and associated cost-of-transport (COT) of free-ranging cetaceans, discounting potential respiration-by-respiration variation in O2 uptake. To investigate ...
Body density and diving gas volume of the northern bottlenose whale (Hyperoodon ampullatus)
(2016-08-17) - Journal article,
Diving lung volume and tissue density, reflecting lipid store volume, are important physiological parameters that have only been estimated for a few breath-hold diving species. We fitted 12 northern bottlenose whales with ...
Whistle characteristics and daytime dive behavior in pantropical spotted dolphins (Stenella attenuata) in Hawai‘i measured using digital acoustic recording tags (DTAGs)
(2016-07-19) - Journal article,
This study characterizes daytime acoustic and dive behavior of pantropical spotted dolphins (Stenella attenuata) in Hawai‘i using 14.58 h of data collected from five deployments of digital acoustic recording tags (DTAG3) ...
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 ...
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) ...
Acoustic deterrent devices to prevent pinniped depredation : efficiency, conservation concerns and possible solutions
(2013-10-31) - Journal article,
Acoustic deterrent devices (ADDs) to prevent pinniped predation on fish farms and fisheries are widely used, but show highly varying success. Recently, ADDs have also been highlighted as a conservation concern due to their ...
Counting whales in a challenging, changing environment
(2014-03-13) - Journal article,
Estimating abundance of Antarctic minke whales is central to the International Whaling Commission's conservation and management work and understanding impacts of climate change on polar marine ecosystems. Detecting abundance ...
Naval sonar disrupts foraging behaviour in humpback whales
(2016-12-29) - Journal article,
Modern long-range naval sonars are a potential disturbance for marine mammals and can cause disruption of feeding in cetaceans. We examined the lunge-feeding behaviour of humpback whales Megaptera novaeangliae before, ...
