Project Team: L. Dueck; R. Seepaul; two assistants from Sachs Harbour, one student

Objective(s): To study whether underwater shipping noise interferes with beluga communication; to record whale calls using a hydrophone array and measure their source dB levels in relation to normal background noise and underwater vessel noise.

Project Description: 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.
