Hydrographic surveying services involves the measurement and mapping of underwater features, typically in bodies of water such as oceans, rivers, lakes, and reservoirs and covering various industries, including marine construction, offshore oil and gas exploration, dredging operations, coastal engineering, environmental monitoring, and navigation safety. Keel Geospatial provides the following hydrographic surveying services:

Multibeam and Single Beam Echo Sounders: Multibeam and single beam echo sounders are primary instruments used in hydrographic surveying to measure water depths. Our multibeam services provide high-resolution bathymetric data over a wide swath of the seafloor. While our single beam services are used for shallow water surveys or where conditions are not suitable for high density coverage of the entire sea floor.

Side-Scan Sonar: Our side-scan sonar surveys are used to create detailed images of the seafloor and the detection of underwater objects such as wrecks, pipelines, and geological features.

Sub-bottom Profilers: We provide sub-bottom profiling aspects with our surveys to help penetrate the seafloor and provide information about sediment layers and geological structures beneath the seabed to identifying potential hazards to navigation, locating buried objects, and studying sediment characteristics.

Establishing a Positioning Systems: Accurate positioning is crucial in hydrographic surveying. Global Navigation Satellite Systems (GNSS), such as GPS, are commonly used for surface vessel positioning. Additionally, Real-Time Kinematic (RTK) and Differential Global Positioning System (DGPS) techniques are employed for precise positioning of survey equipment.

Regulatory Compliance: Our surveys are always led by Certified Hydrographers and many of our staff are recognized hydrographers holding Category A and Category B certificates through ISBC accredited programs. Our Hydrographic surveying services comply with regulatory requirements and standards set by national and international maritime organizations, such as the International Hydrographic Organization (IHO) and adhere to S-44 or Engineering Manual product specifications.
