The Antarctic is the subject of considerable international interest because its geology records the evolution of Gondwana and Rodinia. The geology of the Antarctic is poorly understood, however, due to the region's nearly ubiquitous cover of snow, ice, and water and its harsh environment, which severely restricts field investigations.
Magnetic anomaly data greatly aid geologic studies of the Antarctic, and hence many near-surface magnetic surveys have been carried out by the international community for site-specific geologic objectives since the International Geophysical Year of 1957–1958. At the first workshop of the Antarctic Digital Magnetic Anomaly Project (ADMAP) in Cambridge, UK, it became clear that the data from these magnetic surveys can also be combined into a regional compilation to extend their usefulness for geologic studies of the Antarctic [Johnson et al., 1996; 1997].
