ThayerMahan-UConn Team Begins High-Resolution Seabed Surveys of Thames River

ThayerMahan Press Release, February 11, 2021

ThayerMahan, Inc., a world leader in autonomous maritime security solutions, completed an underwater survey using its SeaScout system to capture high-quality hydrographic imagery of Connecticut's Thames River. The survey is being conducted under a National Institute for Undersea Vehicle Technology (NIUVT) project in conjunction with the University of Connecticut (UConn)'s Department of Marine Sciences.

ThayerMahan's SeaScout system is an actively stabilized towed vehicle with synthetic aperture sonar and multibeam echosounder payloads. The system generates ultra-fine resolution (3cm x 3cm) beamformed imagery and interferometric bathymetry of undersea cables, boulders, rocks, and seafloor characteristics in real-time. For example, individual anchor chain links are visible and discernable in the image shown below:

The two-year project will locate and monitor the shifting boundaries of key biological habitats and short-term, small-scale changes in bathymetry important to the health of the Thames River and Long Island Sound ecosystems. Baseline data will be re-evaluated to identify changes in the region and enhance security within the New London port area.

Michael Connor, ThayerMahan's President and CEO stated,
“ThayerMahan is thankful for the NIUVT project and is very excited about our partnership with UConn. This project, leveraging ThayerMahan's ability to rapidly gather high-quality imagery in real-time, is an important step toward safely developing the Blue Economy offshore and enabling the safe and secure use of our harbors by commercial and government vessels. All ships, particularly those carrying environmentally sensitive cargoes and munitions, should be able to operate in restricted waters confident that neither obstructions nor threats lie in their path. Our seabed imaging capability can make that a reality today. ThayerMahan is proud to support the State of Connecticut and the future of the Port of New London.”
