Harbor and Channel Condition Surveys
Since 1994, TerraSond has consistently met the needs of government, public and private sectors by providing numerous surveys of critical channel navigation points, and surveys in support of engineering and construction projects for ports and harbors.
Project condition surveys for harbors and channels are conducted to monitor channel conditions and dredging requirements. Project condition surveys also determine if project conditions have changed enough to warrant construction, or maintenance activities.
All of our port and harbor surveys are performed using the latest in singlebeam, multibeam, and side scan sonar technology, as well as overseen by an ACSM (American Congress on Surveying and Mapping) Certified Hydrographer.
