PNNL staff operate computer-controlled barotrauma chambers to simulate the pressures that fish may experience when passing downstream through hydropower turbines.

PNNL staff in the Aquatic Research Laboraory use data from its baraotrauma chambers to minimize the impacts of hydropower on downstream migrating fish.

University of Washington researchers deploy their Drifting Acoustic Instrumentation SYstem (DAISY) technology at the PNNL Marine Sciences Laboratory. DAISY develops easy-to-use, readily available, environmental monitoring instruments capable of recording underwater noise near marine energy devices.

Researchers deploys Integral Consulting Inc's NoiseSpotter device in the Sequim Bay channel in Washington State. The device has a sensor system that classifies and provides accurate location information about sounds around marine energy installations.

Small Business Voucher awardee, Whooshh Innovations, designed a fish passage solution using lengths of flexible tube and slight differences in pressure to gently propel fish up and around obstacles in waterways.

A diver inspects the Long Range Target Detection and Classification System developed by BioSonics, Inc. after installation at Pacific Northwest National Laboratory Marine Sciences Laboratory underwater testing platform.

Utah Water Research Lab engineers test a new type of hydrodynamic turbine developed by Percheron Power that is modeled after Archimedes’ screw.

Wave Energy Prize winner, Aquaharmonics, tests their wave energy converter in a flume at Oregon State University.

Pacific Northwest National Laboratory-developed technology, called Sensorfish, collects data to help make turbines more fish friendly.

DOE-supported "Azura" wave energy converter is installed at a U.S. Navy test site in Hawaii.

The length of two grains of rice, Pacfic Northwest National Laboratory's injectable acoustic fish tag is used to monitor the behavior, movement, and habitat use of fish migrating through hydropower dams from freshwater to saltwater.
