Beginning in 2008, Beam Reach partnered with Ballard/Seattle-based Biosonics Incorporated to conduct hydroacoustic surveys in the critical habitat of the southern resident killer whales. Mobile surveys of potential prey (salmon) were first conducted during the spring 2008 Beam Reach program using a 200kHz downward-looking split-beam echosounder. Through a collaboration with The Whale Museum, the same system was deployed horizontally on a fixed tripod to observe passing fish and cabled to a remote monitoring station housed within the lighthouse at Lime Kiln State Park.

Preliminary results from the 2008 deployments were presented as posters at the 2009 Puget Sound Georgia Basin Conference in Seattle (Feb 9, 2009). Digital copies of the posters will be available after the conference:

More analysis was presented in a talk at the spring 2009 meeting of the Acoustical Society of America:
