Core Service: Side Scan Sonar


  • Seafloor mapping
  • Hazard identification


The Side Scan Sonar method uses high-frequency sonar pulses to generate high-resolution seafloor imagery which can be used for the mapping of both natural features and seafloor debris.

Data Analysis & Presentation

Analysis of the collected SSS involves manually reviewing data imagery to delineate surface materials (e.g. surface gravels, rocks) or to identify seafloor hazards such as wrecks, waste material or remnant infrastructure.
