Marine geophysical surveys are critical to any site investigation and/or seabed mapping project. Marine geophysical survey is the science of measurement and description of features which affect maritime navigation, marine construction, dredging, offshore oil exploration/offshore oil drilling and related activities. For hydrographic surveys a strong emphasis is placed on soundings, shorelines, tides, currents, seabed and submerged obstructions that relate to the previously mentioned activities.

Each TDI-Brooks vessel uses an array of specialized tools to conduct marine geophysical surveys. Along with TDI-Brooks pre-mobilized vessels, we offer portable tool kits which can be shipped to any vessel of opportunity.

TDI-Brooks has conducted a number of high-profile marine geophysical surveys (hazard, hydrographic, shallow 2-D seismic, etc). A marine geophysical survey involves a number of data requirements including water depths, seabed topography, seabed and sub-seabed obstructions, seabed soils, shallow geology and ground conditions and identification of any man-made and naturally occurring hazards that may adversely impact the objective of the site investigation (geohazards).

The basic survey package consists of:

  • Side Scan Sonar
  • Conducting cable winch and slip ring
  • Marine Magnetometer
  • Sub-Bottom Profiler
  • USBL system
  • DGPS System and navigation package
  • Single-Beam Echo Sounder
  • CTD Profiler
  • MRU
  • Multibeam Echo Sounder
  • 2D Seismic System
