CLASS 1 HYDROGRAPHIC SURVEYS

 

Client: U.S. Coast Guard, Civil Engineering Unit

Completion Date: 2003

Contract Value: $250K

For 13-years (1991 to 2003), Sea Surveyor conducted Class 1 pre- and post-dredge hydrographic surveys at U.S. Coast Guard Stations in California, Oregon, and Washington. The hydrographic surveys are conducted under contract to the U.S. Coast Guard and include collecting electronic soundings in deep water, leadline depth measurements around docks, monitoring, tides for correcting soundings to the MLLW tidal datum, and preparing bathymetric contour charts.

Sea Surveyor drives to USCG Stations with survey boat in tow and conducts the pre- or post-dredge soundings in one day. Survey equipment includes an INNERSPACE survey-grade depthfinder, differential GPS navigation, self-recording tide guage, and navigation computer with HYPACK software.
