(Public Library of Science (PLoS), 2019-02-26)Baleen whales face the challenge of finding patchily distributed food in the open ocean. Their relatively well-developed olfactory structures suggest that they could identify the specific odours given off by planktonic prey such as krill aggregations. ... -
(Public Library of Science (PLoS), 2019-02-05)Central place foraging theory (CPF) has been used to predict the optimal patch residence time for air-breathing marine predators in response to patch quality. Humpback whales (Megaptera novaeangliae) forage on densely aggregated prey, which may induce ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2021-09)As industries expand in sub-Arctic and Arctic waters there are increased conflicts between these industries and cetaceans. The aim of this work was to investigate the issue of cetacean bycatch/entanglement in Iceland, with a particular focus on the ...
-
(The Royal Society, 2019-03-20)Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals. However, there are indications that cetaceans may learn to associate exposures from distant sound sources with lower ...

Reflections on the ecosystem services of whales and valuing their contribution to human well-being (Elsevier BV, 2020-03)Although whale ecosystem services have been scarcely explored in the academic literature, they illustrate many of the threats, trade-offs and decision-making dilemmas common to marine ecosystem services in general – climate change impacts, the ongoing ...

(Public Library of Science (PLoS), 2019-01-23)Humpback whale songs associated with breeding behaviors are increasingly reported outside of traditional low latitude breeding grounds. Songs from a subarctic feeding ground during the winter were quantitatively characterized to investigate the structure ...

(Elsevier BV, 2019-12)Goal 14, ‘Life Below Water’, of the United Nations Sustainable Development Goals sets a target for nations to increase the number of marine protected areas managed using ecosystem-based management, which requires interventions focused on fish stock ...
-
(The Company of Biologists, 2020-02-27)Anthropogenic noise sources range from intermittent to continuous, with seismic and navy sonar technology moving towards nearcontinuous transmissions. Continuous active sonar (CAS) may be used at a lower amplitude than traditional pulsed active sonar ...

(Elsevier BV, 2020-01)Commercial whaling is a divisive issue in Iceland, and often considered to be irreconcilable with whale watching. The coexistence of both activities in Faxaflói Bay, adjacent to the capital city of Reykjavík, has led to the designation of part of the ...
