The Sea Mammal Research Unit carries out fundamental, cutting-edge research on marine mammals in many different subject areas. This research is carried out worldwide with a core objective of understanding the causes and consequences of changes in populations. With ever increasing pressure on the world's oceans and it resources, marine mammals are consequently often impacted by man's marine activities. One of our main aims is to therefore determine the nature, magnitude and significance of these expanding interactions.

  • Overcoming the challenges of studying conservation physiology in large whales : a review of available methods 

    Hunt, Kathleen E.; Moore, Michael J.; Rolland, Rosalind M.; Kellar, Nicholas M.; Hall, Ailsa J.; Kershaw, Joanna; Raverty, Stephen A.; Davis, Cristina E.; Yeates, Laura C.; Fauquier, Deborah A.; Rowles, Teresa K.; Kraus, Scott D. (2013-05-15) - Journal article
    Large whales are subjected to a variety of conservation pressures that could be better monitored and managed if physiological information could be gathered readily from free-swimming whales. However, traditional approaches ...
  • From the track to the ocean : using flow control to improve marine bio-logging tags for cetaceans 

    Fiore, Giovani; Anderson, Erik; Garborg, C. Spencer; Murray, Mark; Johnson, Mark; Moore, Michael J.; Howle, Laurens; Shorter, K. Alex (2017-02-14) - Journal article
    Bio-logging tags are an important tool for the study of cetaceans, but superficial tags inevitably increase hydrodynamic loading. Substantial forces can be generated by tags on fast-swimming animals, potentially affecting ...
  • Icelandic herring-eating killer whales feed at night 

    Gaëtan, Richard; Filatova, Olga Alexandrovna; Samarra, Filipa Isabel Pereira; Fedutin, Ivan D.; Lammers, Marc; Miller, Patrick (2017-02) - Journal article
    Herring-eating killer whales debilitate herring with underwater tail slaps and likely herd herring into tighter schools using a feeding-specific low-frequency pulsed call (‘herding’ call). Feeding on herring may be dependent ...
  • Whistle characteristics and daytime dive behavior in pantropical spotted dolphins (Stenella attenuata) in Hawai‘i measured using digital acoustic recording tags (DTAGs) 

    Silva, Tammy L; Mooney, T Aran; Sayigh, Laela S; Tyack, Peter Lloyd; Baird, Robin W; Oswald, Julie N (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) ...
  • Phenological sensitivity to climate across taxa and trophic levels 

    Thackeray, Stephen J.; Henrys, Peter A.; Hemming, Deborah; Bell, James R.; Botham, Marc S.; Burthe, Sarah; Helaouet, Pierre; Johns, David G.; Jones, Ian D; Leech, David. I.; Mackay, Eleanor B.; Massimino, Dario; Atkinson, Sian; Bacon, Philip J.; Brereton, Tom M.; Carvalho, Laurence; Clutton-Brock, Tim H.; Duck, Callan; Edwards, Martin; Elliott, J. Malcolm; Hall, Stephen J. G.; Harrington, Richard; Pearce-Higgins, James W.; Høye, Toke T.; Kruuk, Loeske E. B.; Pemberton, Josephine M.; Sparks, Tim H.; Thompson, Paul M.; White, Ian; Winfield, Ian J.; Wanless, Sarah (2016-07-14) - Journal article
    Differences in phenological responses to climate change among species can desynchronise ecological interactions and thereby threaten ecosystem function. To assess these threats, we must quantify the relative impact of ...
