NIUVT, ThayerMahan, and UConn logos 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.
