Marine, River and Transition Zone

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 eg. 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 ie. 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 eg. shipwrecks
• Delineation of ore bodies or other magnetically susceptible geological units
