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 4. Acquire precise GNSS data to contribute to an International Terrestrial Reference Frame solution 5. Develop the geodetic infrastructure of the Antarctic continent through international collaboration (GIANT - expert group of SCAR) 6. Maintain and further develop a precise geodetic infrastructure to support Antarctic research and geospatial activity 7. Collect data on geomagnetic field changes in the AAT and sub-Antarctic as part of Australian and global observatory networks 8. Provide geomagnetic data to Australian and international data repositories for geomagnetic reference field modelling, space weather forecasting, airborne geophysical surveys and research 9. Support compass-based maritime and aviation navigation as required under international treaties 10. Collect seismological data as part of Australian and global observatory networks 11. Provide seismological data for earthquake monitoring, tsunami warning and nuclear test monitoring 12. Provide infrasound data for nuclear test monitoring This is a parent record for other metadata records listed under AAS (ASAC) projects 1159 (Antarctic Geodesy Program [observational]) and 4092 (Geoscience Australia geodetic and geophysical monitoring program).
