Underwater Surveying & Mapping

Our key marine services include:

• Acoustic Doppler Current Profiling (1 unit in-house)
• Large-scale Thermal Profiling (22 thermal arrays in-house)
• Side-scan Sonar
• Depth Surveys (in-house Survey-grade equipment)
• Sub-bottom Profiling
• Diver-performed Habitat Mapping & Characterization
• Substrate Mapping
• Aquatic Vegetation Mapping & Identification
• Fishery Habitat Mapping
• Remotely Operated Vehicles (ROV)
• Underwater Video Documentation / Inspections

ES-Divers provides cost-effective depth and habitat surveys of lakes, reservoirs, and coastal areas using the latest technology. We maintain an in-house inventory of SyQwest survey-grade depth sounders (±1 inch at 1000 feet of water depth) combined with our Trimble sub-meter GPS units. We have the capabilities to perform a wide variety of specialized marine surveys including sub-bottom profiling and substrate mapping, where underwater substrate roughness is mapped automatically using high-powered sonar. We also perform side-scan sonar surveys for identifying underwater objects such as wrecks, containers, and other obstructions. Combined with our advanced GIS Services, these survey tools can provide critical mapping of your project area.

REMOTE OPERATED VEHICLE INSPECTIONS

ES-Divers provides a full range of ROV services available through SeaView Systems. Using a fiber optic umbilical cable, we can provide three channels of high quality video, and inspect pipelines as narrow as 10” in diameter. We offer:

• Long distance penetration up to 10,000 feet
• Intake and discharge inspections
• Hydrographic/bridge and dam surveys
• Multi- and single-beam sonar surveys
• Full complement of reporting, charts, 3D pipewalk, and sonar mosaic
• Scanning & sonar of internal pipe walls
• Potable water tower/tank inspections & reporting
• High accuracy sonar modeling
• Sidescan sonar survey
