Goals for this meeting+
• Discuss logistics of deploying a hydrophone system at the Seattle Aquarium
• Continue considering potential educational benefits (and funding opportunities)
• Monitor and study ambient noise and biological (endangered orca) sound

Outline• Puget Sound hydrophone network overview
– History, precedents, and progress– Proposed nodes and funding status– Research results to date
• The proposed Aquarium node– Components and constraints– Installation and maintenance
• Potential educational benefits– Listening/learning station (pier end, Great Hall)?– Puget Soundscape concept

Conclusions about ambient noisein Haro Strait
• Overall SPL: minimum~95dB; average ~115dB.
• Typical maximum SPL~130dB; maximum~144.
• Ships are dominant source during winters and during summer nights (raising average ~20dB above minimum).
• Boats make significant contribution during summer days (raise average by ~2dB during summer afternoons)
