SVG COMPLETES 168 ACRE MARINE ADVANCED GEOPHYSICAL CLASSIFICATION SURVEY. JULY 2024: SeaView Geophysical, Inc., a Michigan small business specializing in performing Marine Advanced Geophysical Classification (AGC) surveys for unexploded ordnance (UXO), recently completed a multi-month 168-acre survey along the estuarine shoreline of North Carolina. Operating in water depths ranging from 6” to 7ft, SVG believes this is the first example of a full-coverage marine AGC survey to be performed in littoral zone conditions.

SVG AWARDED SUB-CONTRACT UNDER BLACK TUSK GEOPHYSICS TO DEMONSTRATE DEPLOYMENT METHODS FOR MARINE ULTRA-TEM lV: SeaView Geophysical, Inc., a Michigan based small business, has been awarded a sub-contract to Brisbane, Australia based GapEOD. Over the course of three years, SVG will support Black Tusk Geophysics in demonstrating the use of the Marine UltraTEM in various marine environments. SVG’s tasks will include demonstrating the deployment of the Marine UltraTEM Advanced Geophysical Classification system in the Littoral Zone, using SVG’s SurfROVer crawler as a tow vehicle. We will then demonstrate the deployment of the Marine UltraTEM in deep-water from a vessel operating in an active seaway using SVG’s Dynamic Towed Array system using an active heave compensated winch deployed from SVG’s purpose-build survey vessel, GeoSearch.

SVG PERFORMS SEATRIALS ON ACTIVE HEAVE COMPENSATED WINCH AS PART OF ESTCP DEMONSTRATION.
Alpena, MI: In August 2025 SeaView Geophysical, on sub-contract to Black Tusk Geophysics, completed successful inshore trials of an active heave-compensated winch developed by SVG for the deployment of their Active Towed Array used to deploy the GapEOD Marine UltraTEM IV Advanced Geophysical Classifier. The seatrials were the first phase of a multi-phase effort to demonstrate the system's ability to tow SVGs Active Towed Array at depths of greater than 50m at a close altitude from the seabed of 0.5m, even in an ocean swell of 2m significant. Initial trials demonstrated the system’s basic functionality. The next trial phase will be to mobilize the winch onto a vessel of opportunity along with the Active Towed Array and deploy the system in ocean swells.
