Magnetometry

Magnetometry is a critical component of marine surveys when the goal is to detect ferrous objects that may be buried or not visible in acoustic imagery. Using a hypermag we measure subtle variations in the Earth’s magnetic field to identify shipwreck debris, pipelines, cables, anchors, and potential unexploded ordnance. Its self-compensating design improves data quality by reducing magnetic noise from the survey platform, resulting in cleaner, more reliable targets. 

Integrating magnetometer data helps refine survey planning, guide anomaly investigations, and reduce risk before construction or installation begins. When combined with bathymetry, sidescan, and subbottom data, magnetometry provides a more complete and defensible understanding of site conditions.
