Suresh Sethi, director of the Aquatic Research and Environmental Assessment Center and associate professor of earth and environmental sciences, was part of a groundbreaking study that used underwater sound recordings—also known as bioacoustics—to detect the presence of Atlantic sturgeon in the Hudson River.

The team discovered that these large, ancient fish make a unique underwater noise during spawning season, which they dubbed “sturgeon thunder.” By listening for this sound, scientists can identify when and where sturgeon are present without ever having to see them.

This innovative research was a collaboration between Brooklyn College, the New York State Department of Environmental Conservation, Cornell University, and other partners. It shows how new acoustic technology can help scientists monitor and protect sensitive fish species more effectively, supporting better conservation and management efforts.
