U.S. Army dive team members pause for a photo during training on the U.S. Army Engineer Research and Development Center's Coastal and Hydraulics Laboratory's Multifunctional Assessment Reconnaissance Vessel II in New Jersey in May 2019. With just two weeks of instruction, divers are able to assemble and pilot the MARV II, draw a diagram of a damaged pile-supported marine structure, and extract sonar and LIDAR data for a complete structure assessment.
