Wreck surveys
Wreck seen with a SeaBat 7125 off the coast of Denmark
Video of wreck from a SeaBat 7128RESON’s SeaBat multibeam systems are recommended to produce high-resolution bathymetry and imagery areas where wrecks are expected to be found. The 3-dimensional datasets allow investigators to study the environment’s interaction with the wrecks, and also obtain a 3D perspective of the targets’ current condition, state of decay, erosion, and amount of burial.
Unlike towed instrumentation, multibeam sonars provide several discrete soundings and backscatter information collected from a unit firmly attached to the ship’s structure. Recent advances in multibeam design have also enabled the hard, angular surfaces associated with archeological sites to be mapped accurately and with high-resolution.
While a forward-looking sonar can not achieve the perspective available from observing a target with the naked eye, the SeaBat forward-looking sonar systems allow remote verification of features already-imaged through the bathymetry and backscatter data. The sonar systems cover ranges between 120 and 500 meters depending of the model.
Forward-looking multibeam sonars, such as the SeaBat 8128 and SeaBat 7128, can provide valuable ground-truthing imagery, eliminating an immediate need for the deployment of an ROV or diver. SeaBat 8128 forward-looking system uses 240 dynamically focused beams to measure a 120-degree sector. SeaBat 7128 forward-looking sonar system offers 256 dynamically focused beams to measure a 128-degree sector
The backscatter intensity image is displayed in real-time on the sonar display up to 40 times per second. The SeaBat forward-looking sonar systems can be controlled via its native graphical user interface, which is easy-to-use and requires minimal operator training.
