Arc has completed numerous side-scan surveys locating ship wrecks, construction debris and seafloor hard surface areas. Arc performed a side-scan and multibeam survey in New York’s Ambrose Channel identifying the remains of the SS Victoria for removal from the channel by Great Lakes Dredge & Dock.

The company’s side-scan projects require great detail and accuracy as many are used to locate seafloor conditions, exposed pipes, debris prior to dredging in order to avoid differing site condition claims. Arc has performed side-scan surveys in advance of and after pipeline and cable crossing projects in the Caribbean.
