A Guide to Survey and Clearance of Underwater Explosive Ordnance This guide focuses on providing a collection of current policy and best practices used in survey and clearance of underwater explosive ordnance. Specific cases are used; they provide examples and analysis. It is not intended to be a comprehensive database of policies and practices; it […]

Technology Demonstration Report (TDR) for underwater survey equipment in support of Explosive Remnants of War (EWR) technical survey operations. Marine Magnetics’ SeaQuest and AUV Explorer were demonstrated in this 2015 report from Geneva International Centre for Humanitarian Demining (GICHD).    

Released 18 June, 2024, version 1.0.1.3 of Marine’s Firmware Updater enables you to update the transceiver firmware yourself to capitalize on our newest feature releases and critical updates. Compatible devices are: Synapse Synapse Horizontal Transverse Gradiometer Isolation Transceivers made after August, 2023 Sidescan Interface Transceivers for Synapse only, as of Spring 2024 Note: Sidescan Interface […]

Part# M-SS3005 We’ve overhauled the 3 port Transceiver to a 4-port transceiver. The now legacy 3 port transceiver and the evolved 4 port transceiver will continue to offer: All Transceiver Basic Features Provides the ‘topside’ interface to the Synapse, SeaSPY or SeaQuest magnetometer system. Connects to a PC via a RS232 serial or USB port. […]

Report summary Goal: A boat-towed survey to test the Synapse Magnetometer Array System feature set, survey experience, and performance. Sea Trial Date: Spring, 2023 Location: Gurnard Bay, The Solent, UK for its relatively flat bottom, and average depth of 20m. Tow Vessel: 12-meter-long, equipped for nearshore geophysical survey with state-of-the-art instrumentation (auto-pilot, MultiBeam Echo sounder (MBES) and Differential GPS). […]

​Reykjavik, Iceland, April, 2018: Teledyne Gavia, manufacturer of the Gavia Autonomous Underwater Vehicle (AUV), announces the integration of Marine Magnetics’ Explorer AUV magnetometer. Underwater survey work is frequently carried out using autonomous underwater vehicles (AUVs). The benefits of using AUVs are that they are programmed to carry out missions without intervention, can fly at consistent […]

In December 2021, the Chagos Remote Ocean Voyager Expedition (C-Rove) discovered a shipwreck off the west coast of Eagle Island. Bridget Buxton, Associate Professor of Ancient History and Mediterranean Archaeology at the University of Rhode Island, shared this article about the expedition and the role Marine Magnetic’s Explorer played in the discovery. Article summary The […]

By Jim Kirk, business development manager, OceanServer Technology, Inc., Massachusetts, USA Today’s AUVs provide a common-sense approach to the global issue of detecting and monitoring underwater unexploded ordnance Unexploded ordnance (UXO), improperly deployed (or dumped) in the world’s oceans and lakes for the past 70-plus years, are becoming a critical concern for the safety of […]

The conditions were completely unsuitable for boattowed survey, but the Iver2 had no problem. AUVs are powerful platforms for marine survey, wielding an arsenal of sensors and giving the ability to get closer to investigated targets reliably, consistently and inexpensively. Magnetometers have always been a particular challenge to mount on AUVs because of their strong […]

In June 2003, the Naval Undersea Warfare Center (NUWC), Keyport WA, surveyed a small waterway within Puget Sound using a SeaQuest gradiometer system. The goal of the survey was to determine the suitability of the site as a location for the U.S. Navy’s new Electro-Magnetic Field Measurement (EMFM) System, consisting of several stationary magnetic and electric field measurement […]
