Listening for whales

A discussion of hydrophone networks — past and future — with an emphasis on the Salish Sea (Washington State, USA; and British Columbia, Canada)

Talk and discussion hosted by the Puget Sound Chapter of the American Cetacean Society (Facebook event)

January 18, 2017 at the Phinney Ridge Community Center in Seattle

A history of listening to the “Puget Soundscape” (& vicinity)

Discuss: Know of any others, better dates, or old recordings?

Here’s a rough chronology of listening efforts in the Salish Sea, or at least Puget Sound.  Let us know in the comments if you know of others or spy an error!
