We will study the responses of the terrestrial, aquatic and glacial communities of organisms, including the microbes, at both poles to global environmental changes. Our key questions include (a) diversity and biogeography, (b) food webs and ecosystem evolution, and (c) links between biological, chemical, and physical processes in icy ecosystems. This is a huge collaboration involving 17 nations and a wide range of field work.

Antarctica is the primary heat sink in the global climate system: it plays an important role in climate change and variability, and Antarctic atmospheric processes affect the rest of the planet via the atmosphere and the sea. Using satellites and the state-of-the-art HIAPER research aircraft, AC Squared will help scientists gain a better understanding of how these processes work – knowledge that is essential if we are to develop models that more accurately predict global climate change.

The Sixth Continent Initiative aims to introduce scientists from countries who have no experience in Antarctica to the research which is carried out there, during the IPY 2007, as a reaffirmation of the provision of the Antarctic Treaty that dedicates the continent to peace and science for all mankind.

An International Antarctic University The International Antarctic Institute is a consortium being developed by leading global Antarctic educational and research-intensive institutes. Its purpose is to facilitate cooperation and collaboration between member universities in Antarctic undergraduate and postgraduate multi disciplinary education. By sharing teaching resources between international partner universities we can create educational opportunities on a scale unattainable by any one institute or through traditional bilateral alliances.

"Antarctic Sea Ice in IPY is the coordinated project for the sea ice zone surrounding Antarctica, covering over 20 million sqkm (the size of South America) at maximum extent. Our purpose is to determine, for the first time, the circumpolar year-round sea ice thicknesses in this zone. This effort requires extensive ship investigations, coordinated satellite monitoring and use of underwater technologies such as up looking sonar from moorings and use of unmanned autonomous underwater vehicles. The reflectivity or albedo of the earth's surface represents one of the main determinants of surface temperature and, Antarctic sea ice as one of the most large-scale changeable sources of reflected solar energy therefore represents a major contributor to climate and climate change."

UCAA (Upper-ocean characteristics between Africa and Antarctica) During the 26th Indian Antarctic Expedition (IAE), data collection campaign for the above project was launched. Surface meteorological parameters from ship's AWS and density data using XCTD for the upper 1000m of the water column were collected along the ship route: Mauritius-Durban-India Bay (onward journey) and India Bay- Prydz Bay- Mauritius (return journey) on board Emerald Sea. These data are being processed and results are planned to be published by end of 2007.

The SCAR-programme EBA (2004-13) will address the impacts of climate change on species biodiversity, evolutionary adaptations and depletion of marine fisheries on community dynamics in the Southern Ocean. A better understanding of the effect of such changes will be obtained by investigating the acclimatory responses to high latitudes. It will contribute to development of a baseline understanding of sensitive ecosystems.

CAML will investigate the distribution and abundance of Antarctic marine biodiversity, how it will be affected by climate change and how climate change will affect the ecosystem and the planet. Its key focus is a major ship based research programme in the austral summer of 2007-2008. Scientists from 30 countries and 50 institutions will collate data providing a robust benchmark against which future change can be measured.
