growing coalition of scientists, educators, and citizens are working together
to expand a regional hydrophone network in the Salish Sea. This site
is an experiment in sharing real-time underwater sound. The goals are to monitor the critical habitat of endangered
southern resident killer whales to detect orca sounds and measure ambient noise
Listen live via the links in the table or in the pop-up description you get by clicking the green markers on the map. For some hydrophones you can also watch live video from nearby (by clicking on the camera icons). The other icons show other hydrophones in the region that have not yet been networked.
Listening challenge: Help notify researchers when orcas are in the Salish Sea. If you hear killer whales please email firstname.lastname@example.org or log your observations in a collaborative Google spreadsheet. Use the Salish Sea sound tutor to learn to recognize sounds that we commonly hear on the live hydrophones.
If you don't hear anything interesting live, you can hear archived sounds in the "greatest hits" player below, or via the sound archive links in the table. You can also read about past events and acoustic analyses in the blog -- http://orcasound.net/wp/activity

The real-time streams and the Salish Sea hydrophone network are brought to you by these current Network members:
Beam Reach Marine Science and Sustainability School
Colorado College Physics and Environmental Science Departments
Port Townsend Marine Science Center
Orca Behavior Institute
Cetacean Research Technologies
The Network was expanded from 2006-2012 with generous support from the National Ocean and Atmospheric Administration (NOAA). Other major funding has come from the Washington State Department of Fish and Wildlife (WDFW), Beam Reach, and Cornell University (Chuck Greene). We are working to diversify our sources of support and build resiliency into the network. If you would like to contribute financially, please consider making a donation:
To listen to these links, you must be able to receive ShoutCast streams. iTunes
will do the job (on Mac or Windows computers) for free, though you may need to copy the link and paste it in
"Open Audio Stream" under the "Advanced" menu. Another Windows solution is the free
player from Winamp.
You can also try to record the streams when you hear something that interests you. We recommend Stream Ripper (free, open source, all platforms). If you'd like to explore underwater listening even further (including sound analysis and contributions to citizen science projects), then consider taking on a Beam Reach externship in bioacoustics.
Don't hesitate to contact us if you'd like to make your recording available to the listening community by having us publish it on this web site. In any case, please abide by the Creative Commons license
