Near-seafloor AUV surveys to resolve deposits and maximize exploration success
| Sensor type | Application |
|---|---|
| Multibeam Sonar | Seafloor mapping / backscatter strength |
| Synthetic Aperture Sonar | Seafloor imaging / mapping |
| Camera and Laser | UHD seafloor imaging |
| Magnetometer | Subsurface characterization |
| Sub-Bottom Profiler | Subsurface structure |
| Active source EM system | Detection and delineation of conductive bodies in 3D |
| CTD, Oxygen, CH4, pH, Turbidity, Redox | Water column analysis / anomaly detection |
Simultaneous acquisition High data quality at 3-3.5 kn Up to ~440 m footprint
SAS – bridging the gap. Seafloor mapping and exploration with highest ACR
- Exploration at least 2 discoveries at AMOR (Denny et al., 2015)
- Groundtruthing
*Under-appreciated exploration tool

CSEM with inline Source and Receiver AUVs – a 3D modeling example
- Both electric and magnetic data amplitude coincide with horizontal extent of the deposit
- Vertical thickness and conductivity structure can be determined from 3D inversion of the EM data over all survey lines together
- Suitable for the detection and delineation of both Seafloor Massive Sulfides (SMS) and polymetallic crusts (PMC)
- Argeo AUV-CSEM acquisition system can also be used passively for SP and magnetic field measurements; and for IP surveying
All-AUV CSEM – patent-pending solution for both SMS and Crusts
