Responses of Marine Mammals to Vessel Noise
Principal Investigator: Cosens, Susan
Licenced Year(s): 1993 1992
Summary: The research will test playback as a method of studying responses of beluga whales to underwater vessel noise....


Assessment of Potential Masking of Marine Mammal Sounds by Ship Noise
Principal Investigator: Cosens, Susan
Licenced Year(s): 1993 1992 1991 1990
Summary: In Sachs Harbour, the researchers will continue to study whether underwater shipping noise interferes with beluga communication. They will record whale calls and measure their source decibel levels in relation to normal background noise and underwater vessel noise. ship noise....


Site Tenacity of Bowhead Whales and their Vulnerability to Displacement by Disturbance
Principal Investigator: Cosens, Susan
Licenced Year(s): 1990
Summary: The Researcher and team will apply new tag technology and DNA analysis to a study of site tenacity and industrial disturbance of bowhead whales. They will test the feasibility of using sonic tags to track bowheads underwater and will be testing sampling methods for collecting skin from live whales for DNA analysis....


Effects of shipping vessel traffic and vessel noise on the behaviour and distribution of Arctic marine mammals.
Principal Investigator: Cosens, Susan
Licenced Year(s): 1987
Summary: To document the behaviour and distribution of marine mammals in respones to underwater pre-recorded vessel noise and ice-breaking noise; examine the normal behaviour of marine mammals and responses to playback recordings of their own signals. The marine mammals for which these study objectives are primarily aimed at are narwhal, beluga, and bowhead whales....
