"Assessing Vulnerability: Sonar Images Reveal Francis Scott Key Bridge Collapse Aftermath"

Originally Published 1 year ago — by Fox News

Underwater 3D images released by the U.S. Navy show the mangled remains of the Francis Scott Key Bridge at the bottom of the Patapsco River in Baltimore, Maryland, following a cargo ship collision. Salvage operations are hindered by murky water and mud, limiting visibility for divers, and rough weather has slowed debris removal. Two bodies have been recovered, two survivors rescued, and four others are presumed dead. A second temporary channel has been opened, but the challenging salvage operation ahead is underscored by the difficult conditions and the need for detailed verbal guidance for divers due to poor visibility.

Real-time 3D imaging achieved by quantum lidar prototype underwater.

Originally Published 2 years ago — by Phys.org

Researchers have developed a lidar system that uses quantum detection technology to acquire 3D images while submerged underwater. The system uses single-photon detection, which allows high penetration and works even in low-light conditions. The technology could be useful for inspecting underwater installations, monitoring or surveying submerged archaeology sites, and for security and defense applications. The researchers are now working to reduce the size of the system so that it could be integrated into an underwater vehicle.
