Echoes from the Deep
Broadband Sonar Imaging of the Baltimore Bridge Collapse.
When disaster struck, broadband sonar provided a detailed acoustic picture beneath the surface. How did echo reduction reveal hidden details? Dive deeper into the full story.
This imagery, supplied by the U.S. Navy’s Naval Sea System Command (NAVSEA) Supervisor of Salvage and Diving (SUPSALV), shows the wreckage resting at the bottom of the river where the Francis Scott Key Bridge once stood. These 3D images show the sheer magnitude of the very difficult and challenging salvage operation ahead. The underwater sonar imaging tool, known as CODA Octopus, is the primary survey tool used by divers, with visibility clouded to just one to two feet because of the four to five feet of
SADM & Transducer Backing:
Enhancing Underwater Acoustics
Precision engineering meets advanced materials—SADM optimizes transducer backing for clearer sonar imaging, reducing echoes in the toughest marine environments. See how it played a hidden role in this remarkable capture.
