Three PNNL fish researchers recently published a video journal article on how to properly implant miniature acoustic tags in juvenile Pacific lamprey and American eel and how the tags could benefit migration.

During his doctorate work in southeastern Australia, PNNL fisheries engineer Brett Pflugrath examined weirs, or small dams built across rivers, and how they impact fish passage.

Like its namesake, Triton, a Greek god dubbed the herald of the sea, the Triton Initiative aims to deliver messages from the ocean about marine energy and how it affects nearby marine animals.

Following the energy crisis of 2000-2001, the State of Washington received financial settlements from six energy companies, a fraction of which was used for energy-efficiency research.

A new paper found that hydropower turbines with composite blades generate about 20 percent more power than turbines with traditional stainless steel blades at the same flow rate.

Mama and calf humpback whales—considered a vulnerable species that might be entangled in underwater equipment—star in a new animation video that depicts the marine mammals’ scale and movements relative to floating offshore wind farms.

Researchers at PNNL are now leading research to mitigate biofouling and its impacts on the environment and industry

Researchers at PNNL used key metrics to develop visualizations that show how the combined effects of climate change on hydropower and load influence the frequency, duration, and severity of power shortfalls.
