Capsule Resume

Peter has over 12 years experience working on fish passage projects, primarily at federal hydropower and navigation structures in the southeast and Pacific Northwest.  His fish passage work has typically involved the monitoring and assessment of juvenile salmon passage and behavior through turbine intakes, spillways, sluiceways and other bypass structures using acoustic technologies such as fixed-aspect and mobile hydroacoustics, DIDSON, and 3-D acoustic telemetry.  Peter has conducted much of his work for the Army Corps of Engineers at Bonneville, The Dalles, John Day, and McNary Dams on the Columbia River, and at the Chittenden Locks on the Lake Washington Ship Canal in Seattle.

Peter’s most recent work involves the use of acoustic technologies for estimating relative abundance and escapement of salmon stocks in Rivers Inlet, BC and Mill Creek, California.  Additionally, he has been conducting DIDSON sampling in shallow waters of south Florida assessing distribution of juvenile goliath groupers in mangroves habitats.
