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.

  • Seal carrion is a predictable resource for coastal ecosystems 

    Quaggiotto, Maria-Martina; Barton, Philip S.; Morris, Christopher D.; Moss, Simon E. W.; Pomeroy, Patrick P.; McCafferty, Dominic J.; Bailey, David M. (2018-04) - Journal article
    The timing, magnitude, and spatial distribution of resource inputs can have large effects on dependent organisms. Few studies have examined the predictability of such resources and no standard ecological measure of ...
  • Diving behavior and fine-scale kinematics of free-ranging Risso’s dolphins foraging in shallow and deep-water habitats 

    Arranz, Patricia; Benoit-Bird, Kelly; Friedlaender, Ari S.; Hazen, Elliot L.; Goldbogen, Jeremy A.; Stimpert, Alison K.; De Ruiter, Stacy Lynn; Calambokidis, John; Southall, Brandon; Fahlman, Andreas; Tyack, Peter Lloyd (2019-03-12) - Journal article
    Air-breathing marine predators must balance the conflicting demands of oxygen conservation during breath-hold and the cost of diving and locomotion to capture prey. However, it remains poorly understood how predators ...
  • Fin whale density and distribution estimation using acoustic bearings derived from sparse arrays 

    Harris, Danielle V.; Miksis-Olds, Jennifer L.; Vernon, Julia A.; Thomas, Len (2018-05) - Journal article
    Passive acoustic monitoring of marine mammals is common, and it is now possible to estimate absolute animal density from acoustic recordings. The most appropriate density estimation method depends on how much detail about ...
  • Risso's dolphins plan foraging dives 

    Arranz, Patricia; Benoit-Bird, Kelly J.; Southall, Brandon L.; Calambokidis, John; Friedlaender, Ari S.; Tyack, Peter L. (2018-02-28) - Journal article
    Humans remember the past and use that information to plan future actions. Lab experiments that test memory for the location of food show that animals have a similar capability to act in anticipation of future needs, but ...
  • Fin whale survival and abundance in the Gulf of St. Lawrence, Canada 

    Ramp, Christian; Delarue, Julien; Bérubé, Martine; Hammond, Philip Steven; Sears, Richard (2014) - Journal article
    The fin whale Balaenoptera physalus, the second largest species in the animal kingdom to have lived on Earth, was heavily targeted during the industrial whaling era. North Atlantic whaling for this species ended in 1987 ...
