By Natasja Verboom, NeSA B.V., Holland; and Malcolm Morgan & Justin Dunning, Chelsea Instruments Ltd, UK By mounting a magnetometer on a Chelsea Instruments’ NuShuttle undulating towed body, Holland ’s Rijkswaterstaat was able to locate buried wrecks that could not be pinpointed by conventional seismic techniques. THE WESTERSCHELDE, in the South West of the Netherlands, […]
Seismic methods get a boost from magnetic sensing equipment By Doug Hrvoic, President and co-founder of Marine Magnetics Corporation The Acquisition of marine magnetic data on seismic exploration vessels has increased dramatically over the last five years. More sensitive magnetometer equipment, combined with new software processing methods are proving that marine magnetic data can enhance […]

By Doug Hrvoic and Matthew Pozza, Marine Magnetics Magnetic surveying is a common methodology for small-object detection applications such as UXO clearance, pipeline location and archaeology. Now gradiometers using Overhauser technology are doing the job faster and better by directly measuring the analytic signal – a high-resolution data form that is ideal for resolving small […]

This paper provides a thorough description of what a SeaSPY Overhauser magnetometer is, what it does, and how it does it. In doing so, it references advanced concepts in the fields of electromagnetics, quantum physics, and mathematics. However, it does not assume that its audience has a technical background, and its arguments are placed in […]
