Poliservizi carries out marine geophysical surveys for the exploration and monitoring of the seabed and subsoil. These surveys are particularly used in the scientific, engineering and environmental fields, e.g. for the laying of underwater infrastructure and environmental monitoring.

Description of marine geophysical survey activities

1 Main purposes of the surveys:

• Characterisation of the seabed and its physical features.

• Identification of geological and structural anomalies

• Surveys for the laying of submarine cables, gas and oil pipelines

• Exploration and mapping of natural resources

• Monitoring of marine sediments for environmental studies

2 Main methodologies used

• Bathymetric surveys (multibeam or singlebeam)

• Sona side scan surveys

• Magnetometer and gradiometer surveys

• Single-channel seismic surveys (sub bottom profiler)

 3 Applications:

• Offshore nearshore engineering and marine construction.

• Laying and monitoring of subsea infrastructure.

• Scientific research in geology and oceanography.

• Monitoring of contaminated sites and environmental changes.

• UXO ordnance surveys.
