Brief description

Geoscience Australia operates an integrated geophysical observing system in Australia, its neighbouring region and Antarctica. This program represents the Antarctic and sub-Antarctic components of this system. It consists of four key elements: a geodetic element that maintains and develops a precise geodetic infrastructure that supports research and global geospatial activity; a geomagnetic element that monitors geomagnetic-field changes in the polar region; a seismic element that monitors global earthquake activity and nuclear tests; and an infrasound element that monitors nuclear tests.

Project Objectives:
1. Establish and maintain permanent observatories for improved geodetic (Casey, Davis, Mawson, Macquarie Island, Grove Mountains, Prince Charles Mountains and Bunger Hills), geomagnetic (Casey, Mawson, Macquarie Island), seismological (Casey, Mawson, Macquarie Island) and infrasound (to be completed at Davis 2014/15) monitoring in Antarctica.

2. Acquire geodetic data throughout the Australian Antarctic Territory (AAT) to support improving and extending the International Terrestrial Reference Frame (ITRF); monitoring deformations of the solid Earth, variations in sea level and in Earth rotation; determining orbits of scientific satellites; and monitoring the troposphere and ionosphere

3. Provide a common geospatial reference for all Antarctic scientists and operators
