Public Summary |
|---|---|---|---|---|
| 124 | Science | Concentration and isotopic measurements of radiatively important gases in the southern atmosphere [observational] | GEO, GL, MET, OC, SAS | Gases released by human activity (greenhouse and ozone depleting gases) are responsible for global change. They are long-lived and well-mixed in the atmosphere. The Antarctic regions, remote from industrial and land plant activity are ideally located to measure global changes in the gases. The CSIRO sampling network represents the most comprehensive, long-running Southern Hemisphere program. With continuing innovation in measurement and interpretive models, it is ideally positioned to detect possible climate-induced regional changes in carbon uptake, as well as monitor global changes. It also provides essential background information to the new challenge of monitoring integrated emissions from the Australian continent. |
| 187 | Science | Icesheet-atmosphere interaction and surface climatology of interior Antarctica [observational] | GL, MET | Automatic weather stations are used to provide surface meteorological data from remote regions of the Antarctic ice sheet. A network of more than 10 stations is operated. These measure a range of different parameters every hour and relay the data to Australia via a satellite link. The data are used for meteorological forecasting, to support aircraft operations, to provide climatic information, for studies of the surface wind processes over the ice sheet, and to support a variety of other research programs such as the interpretation of proxy climate data in ice cores. |
| 2500 | Science | Variability of the coastal Antarctic climate derived from fast-ice observations. [Observational] | GL, MET, OC | Fast ice is sensitive to change in the (polar) climate system. We monitor the fast-ice (and snow) thickness, its annual growth curve and extent through weekly in-situ measurements offshore from Davis and Mawson stations, East Antarctica. Our data are used to extend an ongoing long-term record at those locations, and combined with meteorological observations to analyze ice-atmosphere interactions, and to identify any changes in the forcing balance. For example, relationships between interannual change in the fast-ice parameters and within the large-scale climate system are explored. Sampling multiple locations near each station enables identification of oceanic forcing on the fast-ice growth. |
