Bush Point hydrophone

Located on the southwest shoreline of Whidbey Island (WA, USA), Bush Point projects into Admiralty Inlet where strong Pacific tides rush to and from Puget Sound. The tidal mixing of sea and river waters attracts marine life, including local sea birds and marine mammals, as well as migrating salmon and killer whales. Many of these species make sounds that can be heard through the Bush Point hydrophone system. The hydrophones also pick up human-made noises, particularly from vessels — both in the nearby shipping lanes and launching from the local boat ramp.

Overview and credits:

Hosted and organized by Howard Garrett and Susan Berta of Orca Network, the Bush Point hydrophone project is a collaboration of many talented team members. The hydrophone is deployed from the Bush Point Wharf B&B thanks to the generosity of owner Stan Yu. The hydrophones are designed and maintained by Lon Brocklehurst and Ken Balcomb of the Center for Whale Research and  Florian Granger of Sealife Productions. Integration with the Orcasound streaming computer system and listening app is provided and maintained by Scott Veirs of Beam Reach. The high-speed Internet connection is supported through a grant from Whidbey Telecom.
