“See” and discuss how noise impacts Southern Resident Killer Whales with Dr. Chris Clark, on Orcas, and San Juan Island at two Public presentations:
San Juan Island: Friday March 31, 7-9 pm, Brickworks, 150 Nichols St. Friday Harbor
Orcas Island: Saturday April 1, 2-4 pm, Emmanuel Episcopal Church, 242 Main St. Eastsound

The Orca Relief Citizens' Alliance is one of a number of groups that believes the Southern Resident whales are the on the brink of extinction, and the cause is due to several threats: shortage of Chinook salmon; pollution; oil spills; and noise and harassment from vessels. The threat least understood by the public is the impact of vessel noise, particularly from motorized whale watch activity.


Orca Relief Citizens' Alliance believes vessel noise is one threat that can be address quickly.

Over the last 10 years, working with his colleague Dimitri Ponirakis, Dr. Chris Clark has developed novel ways to demonstrate, through animation, how human noises in the ocean impact the acoustic environments for a variety of marine mammals, including blue, bowhead, humpback, right, and sperm whales. Dr. Clark’s presentation will show animations of changes in the acoustic habitat of foraging Southern Resident Killer Whales under a variety of whale watching conditions.

DR. CHRISTOPHER W. CLARK, an engineer and biologist, is the founding Director and Imogene Johnson Senior Scientist for the Bioacoustics Research Program at Cornell University’s Lab of Ornithology and Department of Neurobiology & Behavior.. Dr. Clark is also a Senior Research Scientist at Marine Acoustics, Inc. and the Senior Advisor for Planet OS. His research concentrates on animal acoustic communication with a particular interest in the application of advanced acoustic technologies for scientific conservation of endangered species. Most recently he devoted considerable effort to scientific advocacy through documentary films such as Racing Extinction and Sonic Sea, and through outreach. Dr. Clark is deeply concerned about the continued loss of marine acoustic habitats as a result of man-made noise sources. In collaboration with many others, he is working to progress a new, ecologically based paradigm for evaluating and measuring biological risks from anthropogenic activities at individual and population levels. Dr. Clark recently joined the Orca Relief Advisory Board.
