Multibeam Bathymetry

Full-coverage depth mapping using a fan of simultaneous sonar beams rather than a single vertical ping.

Technique

What It Produces

Produces a continuous 3D surface of the seabed across the full swath width, not just a line of soundings — the baseline dataset for charting, dredging design, and repeat-survey change detection.

Scope

Where It Fits

Resolution scales with water depth and platform stability, which is exactly what a small, shallow-draft RIB is suited to close against structure and in water larger survey vessels can't enter.

Platform

Deployed From

Run from the same 7m/9m platforms covered under Platforms, applied to subsea survey work and heritage and conservation missions alike — the technique doesn't change, only the purpose it's deployed for.
