Six disciplines, one team

Land, rivers, reservoirs, coast and offshore: surveys, exploration, investigation, interpretation, evaluation and advisory.

01

Marine & coastal

Hydrographic, geophysical and geotechnical work from beaches and ports to the offshore seabed.

  • Hydrographic and oceanographic surveys
  • Nearshore, inshore and port bathymetry
  • Side-scan sonar and sub-bottom profiling
  • Beach profiling with DGPS and Total Station
  • Tide and current observations
  • GIS-supported marine ecological and fisheries studies
  • Offshore drilling and marine geotechnical investigation

Geological & mineral exploration

Reconnaissance to preliminary exploration, field programmes, laboratory work and resource estimation.

  • Geological mapping and topographic surveys
  • G4 to G2 stage mineral exploration
  • Critical minerals: V, Ga, REE, Nb, Zr, Sc, graphite, bauxite
  • Heavy mineral and placer exploration on beaches and dunes
  • Laterite and associated mineral exploration
  • Polymetallic nodules and crusts; offshore limemud
  • Drilling, sampling and mineral-separation studies

Hydrographic & inland water

Reservoirs, dams, rivers and lakes: capacity, sediment and the resources they hold.

  • Reservoir bathymetry and storage-capacity assessment
  • Siltation and sedimentation studies
  • River-bed mapping with grid-based sediment sampling
  • Lake bathymetry and carrying-capacity studies
  • Storage–elevation curves and bed contours
  • Sand-resource evaluation in rivers and creeks
  • Groundwater exploration, seawater intrusion and recharge studies

  • Marine geotechnical (subsoil) investigation
  • Breakwater and jetty investigations
  • Offshore drilling and vibrocoring
  • SPT drilling in urban areas
  • Exploratory bores and soil classification at dams

Resource & mining advisory

Interpretation, evaluation and technical advice that carries survey data through to decisions.

  • Strategic due diligence and mining strategy
  • Offshore block selection and auction support
  • 3D geological modelling and resource estimation
  • Scoping studies on dredge mining and metal extraction
  • Technical consultancy on offshore mineral rules (OAMDRA)
  • AI-based predictive exploration modelling

From data to decision

Survey data is the start. The decision is the product.

Geo Marine Solutions carries a programme from survey through interpretation to resource assessment and advice. Every step below is backed by work in the portfolio.

Survey

Planning the programme: choosing methods, blocks and survey lines for the environment and the question.

From the portfolio

Offshore limemud block selection for the 2024 auction.
