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
byResolutions
of the Scientific Committee on Antarctic
Research (SCAR) and the International
Association of Geomagnetism and Aeronomy (IAGA).An
international Working Groupand
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.

inception in 1995, ADMAP has contributed
numerous scientific workshops and technical
programs (Activitivies),
products (Databases),
and journal articles (Publications).Additional
