These EM methods have proven ideal tools for the following objectives:

• Groundwater exploration
• Mapping large geologic structures
• Identifying salt-water intrusion
• Determining the depth to an aquitard layer
• Stratigraphy mapping
• Mapping contamination plumes

TDEM

The time domain electromagnetic (TDEM) method has been extensively employed to investigate the vulnerability of Danish aquifers. As a result, advances in both techniques, processing, and analyses have been developed.

Helicopter EM

Helicopter electromagnetic (HEM) is a frequency-domain electromagnetic method employed in partnership with Fugro Airborne Surveys. The DIGital helicopter electromagnetics (DIGHEM) method is used for geological mapping in shallow to moderate depths. Ideal for small survey areas that are difficult to access, the HEM method is applicable in a wide range of applications.

Airborne TDEM

In partnership with Geotech Ltd. and SkyTEM aps, we conduct airborne time-domain electromagnetic surveys. Designed to collect high-resolution continuous measurements, the airborne TDEM method produces data that is comparable to land-based systems, and which is much faster.
