SALE United International Team for Exploration and Discovery;
Subglacial Antarctic Lake Environments (SALE): A Unifying Phenomenon in Antarctic Earth ScienceBeneath Antarctica's ice sheets, water has slowly accumulated over millenia pooling in catchment basins within the continental bedrock. Antarctic subglacial environments are natural macrocosms that, in some instances, trace their origins to more than 35 million years before present, when the continent became encased in ice. Life, especially microbial life, has successfully radiated into most aquatic habitats on Earth. There is little reason to doubt that subglacial environments are exempt from this process.The exploration and study of subglacial environments provides an unparalleled opportunity to advance our understanding of how the expression of life, the environment, climate evolution, and planetary history have combined to produce the world as we know it today.

Inter-discipline Survey along Prydz Bay, Amery Ice Shelf and Dome A The 2000km interconnected Prydz Bay-Amery Ice Shelf-Lambert Basin-Dome A (PANDA) section in Antarctica plays an important role in Antarctic mass balance, sea level and climate change. About thirty observation systems for glaciology, oceanography, geology/geophysics, sun-earth physics, atmospheric science and astronomy will be installed and implemented along the section by the international cooperative expeditions leading by China during IPY2007-2009 and beyond.

The West Antarctic Ice Sheet is currently undergoing rapid change, in particular over the Amundsen Sea Emabayment (ASE) region, and this may lead to accelerated future sea-level rise. Previous aerogeophysical investigations over the Siple Coast reveal that the geology of the West Antarctic Rift System may strongly modulate the dynamics of fast-flowing glaciers that drain the West Antarctic Ice Sheet. But what are the interplays between the virtually unknown sub-ice geology and the apparently thinning and retreating ASE glaciers, such as Pine Island Glacier and Thwaites Glacier? We will utilise new airborne geophysical data collected by UK, US and German teams over the ASE region to provide a unique window on the lithospheric cradle for the West Antarctic Ice Sheet and to study the geodynamics of the largest glaciated rift system on Earth.

International Team Collects New Information about Ice Sheet Growth and Collapse With a Long-range Aircraft in East Antarctica Our international team will conduct an airborne survey over the central East Antarctic Ice Sheet (EAIS), which has been nearly inaccessible until now. We will use a long-range aircraft to fly from a US base deep into the interior of the EAIS over a two-year period. The team will use radar and other airborne instruments to image the EAIS’ internal features and the bedrock below the ice. The observations will allow our team to study ice sheet formation and decay, as well as subglacial lakes, subglacial geology, and changes in ice accumulation through time.

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."

Scientists studying the vast Southern Ocean rarely get the chance to build a bigger picture of their often-specialised research in the Antarctic environment. ICED-IPY is a unique collection of polar scientists from different backgrounds willing to pool their collective talent and look beyond their usual focus to answer one of the biggest questions facing Antarctic science: how polar marine ecosystems operate on a circumpolar scale.

The proposed project focuses the efforts of 20 scientists in 9 countries to produce a series of benchmark data sets for the International Polar Year. Those data sets culminate in the first quantification of the total rate of ice loss by flow from the Antarctic Ice Sheet. This work will be conducted by young scientists mentored by professional scientists to help train the next generation of scientists in the use of remote sensing data of the polar regions. Satellite data include ICESat laser altimetry, Landsat optical imagery and various European and Canadian synthetic aperture radar data.
