Responses of marine mammals to vessel noise
Principal Investigator: Cosens, Susan
Licensed Year(s): 1993 1992
Summary: In this final year of the study, the researcher will be testing the responses of beluga whales to previously recorded underwater (background) and boat noise. The whales' behaviour to the recorded noises will be measured as a way to determine if belugas alter their behaviour to boat traffic....


1) Assessment of Potential Masking of Marine Mammal Sounds by Ship Noise; 2) Responses of Marine Mammals to Vessel Noise
Principal Investigator: Cosens, Susan
Licensed Year(s): 1993 1992 1991 1990
Summary: The field party will work at a camp near the ice edge. The research will study whether underwater shipping noise interferes with beluga communication. Whale calls will be recorded and measured and related to normal background noise and underwater vessel noise. A playback experiment will be conducted to study responses of beluga whales to underwater vessel noise....
