Autonomous Survey Services

High-Resolution Geophysical (HRG) Surveys






Terradepth’s survey solutions are a cost-effective and environmentally friendly Ocean Data as a Service™ (DaaS) solution that reduces personnel and equipment risk while increasing data delivery speed and data accuracy compared to traditional survey services.

REDUCE TIME AND COST UP TO 50%

Smaller, cheaper vessels and smaller teams reduce operational expenses when deploying multiple AUVs to scale operations and drive greater coverage rates per day. Mobilization and demobilization overhead are also dramatically reduced.

INCREASE DATA ACCURACY AND RESOLUTION

A traditional towed system operates a greater distance from the seabed and is less maneuverable, providing less accurate data. AUVs go deeper, navigate easier and are more precise than a towed system in water >30 meters.

CLOSE TO REAL-TIME DATA DELIVERY

The Absolute Ocean (AO) data management solution allows easy visualization and sharing of data as it is being processed. Terradepth’s highly skilled operation team processes and delivers visual and raw data in AO within 1–2 days of collection.

ENVIRONMENTAL ADVANTAGES AND RISK REDUCTION

Terradepth’s AUVs are battery-operated and launched from smaller vessels that require less fuel, generate less noise and eliminate the risk of vessels striking mammals. Terradepth’s AUVs are also mobilized by a small operations team, reducing overall personnel risk.

Our highly configurable and versatile platforms remove the need for continuous human supervision during ocean data collection operations.
