NAVSEA officials used an Echoscope, which according to its manufacturers at CODA Octopus Group, is “the world’s highest resolution real-time 3D/4D sonar technology.”
Sonar technology uses sound to send out acoustic signals, which then bounce off of solid objects. Based on signal strength and how long it takes to return, the technology then proceeds to generate detailed maps and images — which prove crucial in recovery efforts.
Six construction workers were killed in the collapse. Last week the body of 38-year-old Maynor Yasir Suazo-Sandoval was recovered by dive teams. The bodies of three victims remain unrecovered.
