Mapping the Seafloor: Detecting Ghost Nets with Side-Scan Sonar

A single sonar ping can reveal a tangled net resting on the seafloor, but telling it apart from a rock or a reef is where the real work begins. Oceanographers still guide much of the detection process manually, interpreting acoustic returns frame by frame. Ghost nets are difficult to classify because their shape and density vary with depth, current, and decay. Side-scan sonar offers a clear image, yet the final call often rests on human judgment.
