Abstract
Initiated in 1995, the Antarctic Digital Magnetic Anomaly Project (ADMAP) produced the first magnetic
anomaly map of the Antarctic region south of 60
o
S (Golynsky et al., 2001). This map synthesized over 7.1 million line-kms of survey data available up through 1999 from marine, airborne and Magsat satellite observations. Since the
production of the initial map, a large number of new marine and airborne surveys and improved magnetic observations
from the Ørsted and CHAMP satellite missions have become available. In addition, an improved core field model for
the Antarctic has been developed to better isolate crustal anomalies in these data. The next generation compilation also
will likely represent the magnetic survey observations of the region in terms of a high-resolution spherical cap harmonic
model. In this paper, we review the progress and problems of developing an improved magnetic anomaly map to
facilitate studies of the Antarctic crustal magnetic field
