Sub-Bottom Profiling
Detailed mapping of subsurface structure for dredging and wharf infrastructure including pile design;
- Depth to bedrock. Marine seismic reflection and marine seismic refraction
- Determination of geotechnical parameters (e.g. indicative strength/ rippability, elastic moduli). Marine seismic refraction and marine MASW
- Sediment thickness and mapping for dredgeability. Marine seismic reflection and marine seismic refraction
- Calculation of dredging volumes. Marine seismic reflection
Seafloor Survey
Determination of seafloor conditions for risk mitigation, sedimentation and environmental feature mapping using Side Scan Sonar.
- Mapping for shipping hazards i.e. reefs and bomboras
- Location of archaeological significant features (shipwrecks)
- Location of dumped rubbish i.e. car bodies, tyres
- Seafloor monitoring of sediment build up
- Environmental studies for habitat mapping
Magnetic Survey
Magnetometer and gradiometer surveys for UXO clearance, geological mapping and archaeological or environmental mapping
- Locating buried debris (e.g. anchors and unexploded ordnance)
- Marine archaeological survey (shipwrecks)
- Delineation of ore bodies or other magnetically susceptible geological units
