Subsea Survey & Bathymetric Mapping — Côte d'Azur
The French Riviera from Saint-Tropez to Menton — a narrow continental shelf that drops to real depth close inshore, packed with some of the densest marina infrastructure in Europe.
Steep near-shore bathymetry right next to congested moorings is exactly the kind of environment where a few metres of error in a chart matters.
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.
