Geophysical survey is used to identify resources without disturbing or sampling surfaces. This is a ground-based physical sensing technique that detects geological and other substances below the surface, and facilitates the production of a map or detailed image of a particular area.  

             A geophysical survey is essential for surveying any areas that are culturally sensitive an`ds are proposed drilling sites. High quality mapping and interpretations [including 3D], it also undertakes a wide range of tasks, including:  Bathymetric charting, side scan sonar, Sub-bottom profiler, Multibeam and Magnetometers we can deliver quality data of the seabed surface and shallow subsurface that can be used to effectively used in engineering and project planning.                                                                                                                               

            Location and detection of man-made artifacts including debris, shipwrecks, ordnance and sub-sea structures.
Profiling of shallow geological features and structures to assist with engineering studies and facility design.
Sea-floor and sub-surface geotechnical assessment.
          Location and detection of geo-hazards such as shallow gas, hydrates, unstable sea floors, active geological zones and potential shallow water flow-zones to enable exploration drilling, facilities installation and production operations to be performed safely and efficiently.
