We present a novel approach for the combination of aeromagnetic and satellite data
applying an equivalent dipole layer and spherical harmonic (SH) expansion of the dipoles …

Introduction Continental-scale merges of Australian airborne magnetic data (Figure 1) are
only accurate for wavelengths less than about 100 km, due to limitations of survey size …

Advances in regional surveying, particularly the use of satellites, have enabled the mapping
of the internal geomagnetic field at wavelengths intermediate between those due to core …

The composite aeromagnetic anomaly map of Australia, like similar maps of other continent-
size regions, contains spurious trends, warps, and base-level shifts. These arise from the …

Stacked profiles of aeromagnetic data often fail to resolve and display detail as this can be
obliterated by larger amplitude features on adjacent flight lines. Contours and images of …

Combining CHAMP satellite magnetic measurements with aeromagnetic and marine
magnetic data, the global geomagnetic field has now been modelled to spherical harmonic …

Results from equivalent-source distributions derived jointly from high-altitude (average 4 km)
aeromagnetic and Magsat-derived (average 400 km) magnetic anomalies over Canada …

A simple technique is described for removing residual levelling errors from aeromagnetic
data. These residual errors have a distinct spectral signature and are easily removed from a …

The accuracy and sensitivity with which aeromagnetic anomaly data may be collected—and
presented as images for those who seek to maximise the representation of the geological …

A number of modern, multiparameter, high resolution airborne geophysical surveys (termed
HiRES) have been conducted over the past decade across onshore UK. These were …
