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

Changes in water volume tend to be smaller in managed watersheds but occur earlier.
