Electrical resistivity methods provide non-destructive investigation of subsurface conditions by measuring variations in electrical resistance. Applied on land and in shallow-water environments, they support the detection and mapping of buried archaeological structures, geological layers, moisture variations and seabed features. Outputs include georeferenced 2-D, 3-D and time-lapse models and stratigraphic interpretations.
Electromagnetic Induction (EMI) is a rapid, non-contact geophysical method that maps variations in subsurface electrical conductivity and magnetic susceptibility. By measuring secondary electromagnetic fields induced in the ground, it identifies conductive, resistive, or magnetically contrasting features. EMI supports multi-depth investigations of archaeological remains, geological variations, palaeochannels, and sediment changes across terrestrial and shallow-water environments.
Ground Penetrating Radar (GPR) is a non-destructive geophysical method that transmits high-frequency radio-wave pulses into the ground and records reflections from materials with contrasting electrical properties. It supports the detection and depth estimation of archaeological remains, cavities, utilities, bedrock and stratigraphic boundaries, producing vertical radargrams, horizontal depth slices and three-dimensional subsurface models.
Magnetic prospection is a rapid, non-destructive geophysical method that detects buried archaeological and geological features by measuring local variations in the Earth’s magnetic field. Using single- or multisensor gradiometers, it produces high-resolution, georeferenced maps of anomalies associated with kilns, hearths, walls, pits, ditches, disturbed soils, and metallic objects on land or in shallow-water environments.

Seismic methods investigate subsurface structures by analysing P-wave and surface-wave propagation through soils and rocks. Seismic Refraction Tomography and Multichannel Analysis of Surface Waves reveal variations in material density, rigidity, saturation and stratigraphy. The service produces velocity profiles and sections supporting archaeological detection, geological interpretation, geotechnical assessment, aquifer mapping and hazard investigation.
