Deep-Sea Minerals – Understanding the challenges

Source: Company

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
