Series of High-res Surveys to Track Changes in Thames River

A two-year project aims to locate and monitor the shifting boundaries of key biological habitats and short-term, small-scale changes in bathymetry important to the health of Connecticut’s Thames River and Long Island Sound ecosystems.
Marine technology company ThayerMahan, which recently completed an underwater survey using its SeaScout system to capture high-quality hydrographic imagery of the river, said 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.

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.
