Nearshore Bathymetry, Magnetometer & SDB Survey
USV-Based Multi-Sensor Seabed Mapping
Our team successfully executed a nearshore hydrographic survey campaign together with Vikra Ocean Tech using the WAVEBOT USV, integrating multiple survey technologies to deliver comprehensive seabed intelligence for engineering and shoreline planning.
1. Challenge
The survey required comprehensive coverage across inshore topographic/bathymetric and offshore bathymetric & magnetometer zones, with the objective of mapping the seabed and identifying potential buried pipelines, cables and ferromagnetic objects in a challenging shallow-water environment. Survey coverage components: Bathymetry (MBES), Magnetometer Lines, Side Scan Sonar, SDB Coverage, and Camera Path.
2. Our Approach & Solution
- Multibeam Bathymetry: Full-coverage MBES data acquired using NORBIT iWBMS multibeam echosounder mounted on the USV.
- Magnetometer Survey: Marine magnetometer towed behind the USV along lines parallel and perpendicular to the shoreline to detect ferromagnetic anomalies and buried utilities.
- Satellite-Derived Bathymetry (SDB): SDB used alongside acoustic data to extend depth coverage and cross-check results across the wider nearshore area.
- Side Scan Sonar: SSS imagery used to characterize the seabed and identify natural features such as rock/coral outcrops and boulders.
- Underwater Camera (GoPro) Inspection: Towed GoPro provided visual ground-truthing of coral, boulders and sand ripple fields across the nearshore zone, supplementing the geophysical data.
- Processing: All datasets were acquired and processed using HYPACK/HYSWEEP, generating validated bathymetric surfaces, magnetometer plots, and seabed classification for engineering review.
