The Deepwater Horizon oil spill marine mammal injury assessment
(2017-01-31) - Journal item,
From 2010 to 2015, a team of scientists studied how the BP Deepwater Horizon (DWH) oil spill affected marine mammals inhabiting the northern Gulf of Mexico, as part of the DWH Natural Resource Damage Assessment process. ...
Fishing for drifts : detecting buoyancy changes of a top marine predator using a step-wise filtering method
(2015-12-02) - Journal article,
In southern elephant seals (Mirounga leonina), fasting and foraging related fluctuations in body composition are reflected by buoyancy changes which can be monitored by changes in drift rate. Here, we present an improved ...
Aerial low frequency hearing in captive and free-ranging harbour seals (Phoca vitulina) using auditory brainstem responses
(2016-12) - Journal article,
The hearing sensitivity of 18 free-ranging and 10 captive harbour seals (Phoca vitulina) to aerial sounds was measured in the presence of typical environmental noise through auditory brainstem response measurements. A focus ...
Sex-related differences in the postmolt distribution of Weddell seals (Leptonychotes weddellii) in the southern Weddell Sea
(2018-04) - Journal article,
The population of Weddell seals (Leptonychotes weddellii) in the southern Weddell Sea is in a unique position on the continental shelf edge, with vast shelf waters to the south, and deep Southern Ocean to the north. We ...
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 ...
Genetic population structure of harbour seals in the United Kingdom and neighbouring waters
(2017-08) - Journal article,
1. In the United Kingdom (UK), several harbour seal (Phoca vitulina) populations have been declining over the past decade. In order to understand the effect of these changes in abundance, this study seeks to determine the ...
Circumpolar habitat use in the southern elephant seal: implications for foraging success and population trajectories
(2016-05-26) - Journal article,
In the Southern Ocean, wide-ranging predators offer the opportunity to quantify how animals respond to differences in the environment because their behavior and population trends are an integrated signal of prevailing ...
Harbour seal (Phoca vitulina) abundance within the Firth of Tay and Eden Estuary, Scotland : recent trends and extrapolation to extinction
(2017-02-17) - Journal article,
1. Aerial surveys have detected alarming declines in counts of harbour seals in several regions across Scotland. 2. Demographic data and simple models were used to examine the recent decline in the numbers of harbour seals ...
Individual size, sex and rearing environment impact on aggression in newly weaned seals
(2017-04) - Journal article,
Population structure of humpback whales in the western and central South Pacific Ocean as determined by vocal exchange among populations
(2015-08) - Journal article,
For cetaceans, population structure is traditionally determined by molecular genetics or photographically identified individuals. Acoustic data, however, has provided information on movement and population structure with ...
