Antarctica and global change research
1992
The Antarctic, including the continent and Southern Ocean with the subantarctic islands, is a critical area in the global change studies under the International Geosphere-Biosphere Program (IGBP) and the World Climate Research Program (WCRP). Major scientific problems include the impacts of climate warming, the ozone hole, and sea level changes. Large-scale interactions between the atmosphere, ice, ocean, and biota in the Antarctic affect the entire global system through feedbacks, biogeochemical cycles, deep-ocean circulation, atmospheric transport of heat, moisture, and pollutants, and changes in ice mass balances. Antarctica is also a rich repository of paleoenvironmental information in its ice sheet and its ocean and land sediments.
