FAQ
Frequently asked questions.
What does Gianluca Ottaviani do?
Gianluca Ottaviani is an independent geologist based in Rome, Italy. He offers consultancy in three fields: mineral exploration, marine geophysics and geological data analysis, covering the whole project from survey design and data acquisition to processing and final geological interpretation.
Which geophysical methods are used?
Projects have used seismic reflection, gravimetric surveys, geoelectrical (electrical resistivity) surveys, high-resolution bathymetry, nearshore geophysical route surveys and ROV seabed inspections, chosen according to the geological question and the site, offshore or onshore.
Where does he work?
He is based in Rome and works across Italy, the Mediterranean and Africa. Past projects include the Medusa subsea cable landfalls (Italy and Algeria), the new port of Fiumicino, the Ponza archipelago, the Pedemontana Marche road, and exploration and infrastructure surveys in Morocco and along the Nigeria–Morocco Gas Pipeline.
What kind of projects can he support?
Typical work includes route surveys and hazard assessment for subsea cables, interconnectors and pipelines; bathymetric and geophysical surveys for ports; geological investigations for roads and infrastructure; and exploration campaigns for potash, manganese, base metals and industrial minerals.
