Subsea Survey & Bathymetric Mapping — Costa Smeralda

Sardinia's northeastern coast — granite headlands, clear water, and one of the Mediterranean's busiest concentrations of marinas around Porto Cervo.

A mostly rocky seabed and heavy seasonal vessel traffic make accurate approach-channel and mooring-field data genuinely useful, not just a nice-to-have.

What this survey work covers

Small RIBs give access to the shallow, congested, and often poorly-charted water that larger survey vessels can't reach — inside marinas, along seawalls, up river channels, and close against structures. Combining multibeam sonar for the underwater surface with photogrammetry for the shoreline and any structures above the waterline produces a single 3D model spanning both, rather than two separate datasets that have to be stitched together after the fact.

What it's used for

• Environmental and habitat monitoring — tracking change in the seabed or shoreline over repeat surveys.
• Marina, mooring, and port infrastructure condition surveys.
• Pre-construction and dredging bathymetry, and cable or pipeline route surveys.
• Baseline data feeding a heritage or environmental impact assessment where one applies.
