Acoustic and Hydrographic Surveys

Marine and Shallow Water Geophysics

It supports ports, coastal infrastructure, offshore energy, and nearshore development where seabed and shallow stratigraphy matter.

Definition

What this method is

Marine and shallow-water geophysics combines hydrographic and sub-bottom methods to characterize seabed and shallow subsurface conditions.

It supports ports, coastal infrastructure, offshore energy, and nearshore development where seabed and shallow stratigraphy matter.

How It Works

From field measurement to interpreted model

  1. 1Survey planning aligns vessel logistics, depth range, tides, and project targets.
  2. 2Marine geophysical and hydrographic datasets are acquired along planned lines.
  3. 3Integrated interpretation produces seabed and shallow subsurface models for engineering decisions.

When to Use

Best-fit conditions for this method

  • Nearshore infrastructure and reclamation planning
  • Offshore wind and coastal energy investigations
  • Seabed hazard and shallow stratigraphy screening

What It Can Help Identify

Subsurface features and signals

  • Seabed features and shallow sediment boundaries
  • Potential shallow marine hazards and obstructions
  • Zones requiring additional marine verification

Deliverables

What you receive

  • Marine geophysical interpretation sections
  • Seabed and shallow stratigraphy maps
  • Risk-focused recommendations for follow-up

Typical Outputs

What the data looks like

  • Seabed map
  • Sub-bottom profile
  • Marine risk screening map

Applications

Common applications in the Philippines

Port, jetty, and coastal infrastructure projects

Offshore wind and marine cable corridor studies

Nearshore baseline characterization programs

Method Limitations

What this method cannot do alone

  • Survey windows depend on weather, tide, and vessel access constraints.
  • Data quality and method reach vary with water depth and seabed conditions.
  • Interpretation should be validated with direct marine investigation where required.

Geophysical results are interpreted models based on measured physical property contrasts. Results should be correlated with boreholes, test pits, drilling, geological mapping, laboratory data, or other direct investigation methods where required.
