Geo SubSea offers a wide range of services supporting freshwater and marine projects worldwide.
If we don’t have the expertise to assist you, we will find someone who can.

Survey Support

Assisting teams around the globe

  • Geophysics

    Strong familiarity with many different equipment manufacturers systems of side scan sonar, magnetometer, gradiometer, seismic reflection (chirp, pinger, boomer, sparker sound sources) and refraction (air gun sound source), as well as single and multibeam bathymetry echosounders.

  • Geotechnical

    Geo SubSea is very familiar supporting geotechnical investigations that include all types of coring devices; field sampling via push, gravity, piston, vibratory, and electric corers, as well as jet probing.

  • Oceanographic

    Deployment experience with a wide range of oceanographic and environmental sensors including ADCPs, tide and wave gauges, turbidity and water quality sondes; short to long term installations using satellite telemetered data back to the office.

  • Benthic

    Geo SubSea has extensive experience mapping benthic habitats from initial sonar surveys recording acoustic reflectivity and backscatter to ground truthing via grab samplers, underwater video (cameras and ROVs), SPI (sediment profile imaging), and diving.

  • Positioning & Navigation

    The company is familiar with a wide range of GPS solutions from DGPS to RTK for vessel and boat mounted transducers to USBL tracking for towed sensors and submersibles; all integrated into HYPACK/Qinsy for navigation and data logging.

  • Inspection

    We have experience supporting the use of remote sensing and underwater camera systems for inspection of seafloor features, including ROVs, AUVs, underwater still and video cameras; work supports a wide range of tasks from search and recovery to benthic mapping to marine archaeology assessment.
