Marine Route Surveys
Marine Route Surveys are necessary for choosing the safest and most efficient route for a cable or pipeline project. In addition to conducting these hydrographic surveys, TerraSond works closely with the engineer and investigates all available sources of information along the marine route. Investigations include navigation charts, geological resources, existing petroleum, fishing, cable information, and any other information on obstructions, man-made or otherwise.
