Class 1 Hydrographic Surveys

Sea Surveyor conducts hydrographic surveys using single-beam and multibeam depth sounders with hull-mounted transducers.  We use the most stringent Class 1 standards required by the U.S. Army Corps of Engineers for pre- and post-dredge hydrographic surveys.  Sea Surveyor’s hydrographic surveys are typically used for:

• Nautical Charting
• Multibeam Sonar Surveys
• Class 1 Pre-Dredge Surveys
• Lake and Reservoir Surveys
• River Navigability Surveys
• Beach Transects and Profiles
• Emergency Assessment Surveys
• Marine Vegetation Mapping
