Antarctic Digital Magnetic Anomaly Project (ADMAP) Expert Group
The Antarctic continent plays a very important role in the plate tectonics context; the study of the lithosphere and the identification of relevant lateral discontinuities in Antarctica and surrounding areas are essential to the understanding of the geodynamic evolution of the continent.
Studies of the Antarctic continent rely extensively on magnetic anomaly data, because of the extensive ice cover. Numerous magnetic surveys have been carried out by the international community. The objective for compiling the Antarctic digital magnetic database is to enhance the geological and tectonic utility of these magnetic data. This compilation will provide an improvement in understanding the regional geology of the Antarctic, provide a regional framework for the interpretation of smaller scale areas and enable a more effective selection of areas for further investigation.
The multinational Antarctic Digital Magnetic Anomaly Project (ADMAP) was launched to compile near-surface magnetic anomaly data into a digital map and database for the Antarctic continent and surrounding oceans. The data set will be a powerful tool for determining the structure, processes and tectonic evolution of the continent, together with providing information valuable in the reconstruction of the Gondwanaland and Rodinia supercontinents. The resulting merged potential field anomaly maps connect geological mapping studies of the various programmes in terms of parameters such as:
