Scientists Use Sound to Monitor the Ocean in 3D
Original: Advancing Active Acoustics: How Scientists Use Sound to Monitor a Three-Dimensional Ocean
NOAA Fisheries scientists are advancing active acoustics, a technique that sends sound pulses into the water and reads the echoes to map marine life and ocean conditions in three dimensions. The approach allows researchers to survey fish stocks and ecosystems across whole water columns more efficiently than traditional trawl-based methods, offering a clearer picture of how ocean life is distributed and changing.
Why now: Renewed scientific and policy interest in better ocean monitoring tools as marine ecosystems shift.
