Geophysical Surveying
Magnetometry
The measurement of small variations within the Earth's magnetic field enables the location and mapping of buried features both manmade and natural.
Magnetometry has a wide variety of applications including archaeology, environmental investigation and structure location. Features that can be identified include most metallic objects, reinforced concrete, buried mine caps, piles, natural igneous rock formations, archaeological walls and ditches, large pits, kilns, and burnt areas.
We utilise the Geometrics G858 Magmapper Caesium Vapour Gradiometer, which when integrated with real-time RTK GPS positioning allows us to acquire accurate data efficiently.
