Thank you to The Hydrographic Society of America (THSOA) Southeast Chapter and The University of Southern Mississippi for hosting an engaging Technical Lunch & Learn — “Today’s Challenges, Tomorrow’s Tools.” , an OceanSight company, was delighted to take part in the technical conversation.

It was a pleasure for Matthew Kowalczyk to present “Towing from small USVs is hard…so why do it?” and discuss how OFG’s patented technology enables high-fidelity magnetic measurements directly from marine robotic platforms without towing. By rigidly integrating vector magnetometers and applying real-time compensation, robotic systems such as USVs, ROVs, and AUVs can acquire high-quality magnetic data while reducing operational risk and survey complexity.

Thank you to Kim Dailey of Survey Equipment Services (SES) and Mike Nitska of HydroTerra Technologies, LLC for the invitation, and to everyone who joined the discussion.

We appreciate the opportunity to connect with colleagues across the hydrographic and marine robotics community and share perspectives on emerging tools for subsea survey and inspection.

Ocean Floor Geophysics (OFG) and GeoAcoustics Ltd have teamed up to tackle a long-standing challenge in operations: how to combine high-resolution and data without the complexity, risk and deck handling issues of multiple towfish.

The result is a new single-towfish configuration that integrates GeoAcoustics’ GeoScan side scan sonar with OFG’s Self-Compensating Magnetometer ( ). By mounting the SCM directly to the tail of the GeoScan towfish, the system brings acoustic imaging and magnetic detection together in one streamlined platform for the first time.

OFG’s real-time self-compensation technology allows the magnetometer to operate effectively in close proximity to metallic survey hardware, removing the need for long layback distances from the SSS towfish and multiple tow cables. It significantly simplifies launch and recovery, improves efficiency and reduces operational risk, particularly for USVs.

Ocean Floor Geophysics delivers the only magnetometer and electric-field measurement solution that enables marine robotic platforms to acquire best in class, high-fidelity data, without towing, reducing risk to people and assets.

Backed by deep operational and system expertise, we lower survey complexity and overall cost without compromising results.

Low-ferrous detection with ScanFish + eBOSS + HyperEMF + HyperMag

We’re excited to announce at Oceanology International 2026 a new collaboration between Ocean Floor Geophysics (OFG) and EIVA a/s.

Together, we have deployed OFG’s advanced self-compensating magnetometer technology and our electric field sensing system into EIVA’s Katria towed sensor platform, tightly integrated with the EdgeTech Marine — delivering a seamless, high-performance, multi-physics survey solution.

This integration means:
✔ Detection of non-ferrous and low-ferrous UXO
✔ Improved target discrimination and ranking
✔ Reduced survey complexity
✔ Lower operational risk for equipment and personnel
✔ Lower operational costs
✔ Faster, safer deployment
✔ High-resolution vector data
✔ Greater operational efficiency

By embedding advanced sensing directly into marine robotic systems, we’re making geophysical surveys smarter, safer, simpler, and more scalable.

We look forward to working with EIVA and EdgeTech to bring this next-generation capability to the market.

The future of Ocean Floor Geophysics is integrated.
And we’re bringing it to Oceanology International 2026 – Booth L100.

For years, subsea magnetometry deployed with sidescan sonars required two tow-bodies Multiple sensors. Multiple deployments. Multiple tow-fish in the water. Higher complexity. Higher operational risk.

OFG and Klein Marine Systems, Inc. are collaborating to make this a thing of the past.

Together with Klein, we’re developing an integrated system ➡️ The OFG multi-sensor self-compensating magnetometer system + Klein's 5900 bathymetric sidescan. The combined system will provide high resolution magnetic vector and gradiometer data combined into a single towbody with Klein’s field-proven sonar system delivering detailed underwater imagery and bathymetry. A single, streamlined solution.

What does this mean for marine survey operations?
✔ Reduced survey complexity
✔Lower operational risks for operators and equipment
✔ Faster, safer deployment
✔ High-resolution magnetic vector and gradiometer data
✔ Smarter seabed intelligence

From cable and pipeline mapping to UXO/MCM, to archaeology, geological mapping, to critical infrastructure monitoring — integrated sensing is redefining how we approach subsea geophysics.

This isn’t just another sensor package.
It’s a shift toward scalable, efficient, platform-embedded geophysical and sensing capability.

We look forward to continued cooperation with Klein as we equip their next generation of sidescan sonars with OFG Self-Compensating Magnetometer technology — advancing smarter, more capable seabed survey systems together.

If you’re working in offshore energy, security, marine survey, or subsea infrastructure — this is a conversation you can’t afford to miss.

📍 Visit OFG at Booth L100 and Klein at Booth J100at Oceanology International 2026 to hear about the new standard in subsea geophysical surveys.

Let’s talk about the next generation of Ocean Floor Geophysics.

Problems with low-ferrous UXOs? We have a solution.

OFG looks forward to connecting with colleagues and partners this week at Tekna’s Seabed Mapping and Inspection 2026, taking place March 4–6 in Geilo. The event brings together technology developers, service providers, and practitioners across offshore energy and seabed minerals to exchange insights on seabed mapping and inspection.

We are looking forward to N-Sea Group’s presentation on March 5 by Florent Aguesse, “Advancing Low-Ferrous UXO Detection: Correlating Magnetic and Electric Field Anomalies on a Multi-Sensor Towed Platform,” which incorporates OFG’s patented and system as a key sensor of their multi-physics system for wind farm site and route surveys.

Hypermag is a scalable array of three-component magnetometers designed with proprietary compensation algorithms to overcome platform magnetic interference. HyperEMF combines magnetic and electric field sensors for detection and characterization of low-ferrous targets.

Or, if subsea asset integrity and inspection is your interest and you have questions about OFG’s patented AUV system for non-contact inspection of pipelines then come find OFG’s Richard Humphreys. He will be attending and welcomes the opportunity to connect. 🤝
