(Antarctic Digital Magnetic Anomaly Project)

The Antarctic is the most poorly understood region of the planet.  However, its geology maintains an important record of Gondwana and Rodinia evolution, and thus the Antarctic is the focus of extensive international scientific inquiry.  Geological studies of the Antarctic are greatly aided by magnetic anomaly data because of its ubiquitous cover of snow, ice, and sea water.  Accordingly, numerous terrestrial, marine, and airborne magnetic surveys have been carried out for site-specific geologic objectives by the international geoscience community.

As a result of the first ADMAP workshop at the British Antarctic Survey (Cambridge, UK) in 1995, it became clear that the individual near-surface surveys may be combined into a regional anomaly compilation to substantially enhance their utility for geological studies.  In addition, state-of-the-art satellite magnetic survey missions can help to fill-in the regional coverage gaps between the near-surface surveys, and also enhance the compilation’s regional crustal magnetic anomaly attributes.  Accordingly, ADMAP was launched in 1995 to compile and integrate into a digital database all near-surface and satellite magnetic anomaly data collected in Antarctica and surrounding oceans south of 60oS.

This multinational project is encouraged by
Resolutions of the Scientific Committee on Antarctic Research (SCAR) and the International Association of Geomagnetism and Aeronomy (IAGA).  An international Working Group and its steering committee (Contact Information) implement ADMAP’s objectives and protocols to collect, archive, and make available to the World Data Centers (e.g.,  NGDC ) magnetic anomaly data typically within a few or less years of the completion of surveying.  ADMAP also contributes to IAGA’s  World Digital Magnetic Anomaly Map

Recently, the 2nd generation ADMAP, including more than 3.5 billion line-kilometer data collected past 50 years, were compiled to accomplish a new version of ADMAP (called as ADMAP-2) by the support of Korea Polar Research Institute and other groups.  The used data that more than doubles the initial ADMAP1, were corrected for the IGRF, diurnal effects, and high-frequency errors and leveled, gridded, and stitched together.

New  New ADMAP-2 model (ADMAP-2s) is now available here!

Since its inception in 1995, ADMAP has contributed numerous scientific workshops and technical programs (Activitivies), products (Databases), and journal articles (Publications).  Additional details concerning ADMAP’s progress may be obtained from members of the steering committee (Contact Information) and the Working Group.
