Technical procedures for aeromagnetic surveys in Antarctica during the Italian expeditions (1988-1992)

Annals of Geophysics, 1994
For most of Antarctica, the geophysical data now available are those of aeromagnetic surveys performed there from 1950 to 1960. Until 1984, the inaccurate positioning and insufficient monitoring of geomagnetic time variations allowed the investigation of

High-Precision Source Positions Obtained by the Combined Inversion of Different-Order Local Wavenumbers Derived from Aeromagnetic Data

Remote Sensing, 2022
The aeromagnetic survey is a common remote sensing tool for detecting iron deposits. The local wavenumber of a magnetic anomaly is used to interpret the edges or positions of the sources, and can involve first- or second-order local wavenumbers.
