QAMT – Passive Airborne EM (AFMAG)

INTRODUCING THE QAMT SYSTEM

The QAMT system is a lightweight helicopter-borne AFMAG (magnetovariation tellurics) survey system, which passively measures the earth’s natural electromagnetic field. The system delivers low-noise, 3-component mobile data using LT SQUID (superconducting quantum interference device) sensors that are capable of acquiring unparalleled data quality.

Over the last decade, natural field airborne EM methods have advanced significantly. They are known to provide valuable subsurface information for deep targeting and large-scale mapping. Single component passive EM systems do not provide adequate levels of certainty in resistivity imaging. The QAMT, with low-noise and 3-component mobile acquisition, now provides a new standard of resolution and depth capability for this airborne method. Data sets can be acquired with greater confidence and will deliver a clearer and deeper imaging result.

The SQUID sensors are developed by Supracon AG of Jena, Germany. Operating within a liquid helium bath, the sensors measure the electromagnetic field with unrivaled sensitivity. The sensor system is the result of over 20 years of development and testing.
