Raised on the coast of Maine, Dr Haley Viehman has been drawn to the ocean her whole life. Starting in civil and environmental engineering, she discovered her passion for marine science by studying how fish interact with tidal energy turbines in fast‑flowing waters. In this week’s episode, we hear how Haley uses hydroacoustics to uncover how fish move, behave, and adapt in extreme tidal environments. Now based in Tasmania as a Hydroacoustic Specialist at Echoview Software, she supports researchers around the world who use sound to understand aquatic life, renewable energy, and the rapidly growing blue economy.
