For about three decades, airborne electromagnetic (AEM) systems have been used for
groundwater exploration purposes. Airborne systems are appropriate for large‐scale and …

Electrical and electromagnetic (E&EM) methods for near-surface investigations have
undergone rapid improvements over the past few decades. Besides the traditional …

Buried valleys are underground structures typical for areas affected by glaciations.
Especially when the glaciers met poorly consolidated ground, ie in sedimentary basins …

We want to develop a dialogue between geophysicists and hydrologists interested in
synergistically advancing process based watershed research. We identify recent advances …

This paper presents a tutorial review of electrical and electromagnetic (herein collectively
called geoelectromagnetic) methods as applied in the search for natural resources. First, the …

Airborne electromagnetic (AEM) surveys can contribute substantially to geologic map**
and target identification if good-quality multifrequency data are produced, properly …

Two different airborne electromagnetic methods were applied in the same area: the
frequency-domain helicopter-borne electromagnetic (HEM) system operated by the Federal …

Helicopter-borne frequency-domain electromagnetic (HEM) surveys are used for fast high-
resolution, three-dimensional resistivity map**. Standard interpretation tools are often …

Common situations encountered in geophysical investigations involving environmental and
engineering problems call for simple and fast onsite interpretation of the survey data so …

Introduction Electromagnetic methods have a special place in the arsenal of geophysical
