ANTPAS was involved in the International Polar Year (IPY), which ran from 2007-2008, in a number of ways. Below follows information on the projects that ANTPAS was involved with. More on individual project contributors and contributions to the IPY can be viewed on the IPY Project Contributors page.

CALM-S/GTN-P MONITORING GROUP
Objectives
The current Circumantarctic Active Layering Monitoring program (CALM-S) will be expanded to 12-15 sites distributed along an environmental gradient from the peri-Antarctic islands through the Antarctic Peninsula and Trans-Antarctic Mountains to the McMurdo Dry Valleys, complemented by 2 to 3 coast-inland transects. In view of the unique conditions in the Antarctic region (abundant coarse fragments that preclude probing, the existence of "dry" permafrost), a protocol for monitoring the active layer will be established and a manual describing recommended techniques will be prepared.
Coordinators

- Ron Paetzold will coordinate existing and new sites and data management;
- E. Serrano will coordinate periglacial processes; and
- Frederick Nelson and Jan Boelhouwers will coordinate protocols/manual, network configuration, and scaling issues.
PERMAFROST GROUP
Objectives
Coordinators
Ron Sletten, Ian Campbell, James Bockheim, D. Gilichinsky, Mauro Guglielmin, with the following subgroups:
Objectives
- An expert group will prepare a database and map showing the distribution of permafrost in the Southern Hemisphere. A draft of the map will be available by June 2007 with the final map being presented at the 2008 ICOP meeting in Fairbanks, Alaska (USA). The map legend will include:
- Ice-covered (sub-glacial) permafrost (contours of basal temperature from models extrapolated from specific boreholes, extent of lakes and water layers, thickness of permafrost from models, and specific borehole data);
- Ice-free permafrost (ground ice, lithology and mineralogy, thickness of permafrost from models, temperature, specific borehole data, and depth to an ice-bonded layer);
- Sub-sea permafrost; and
- Andean permafrost.
- Ice-covered (sub-glacial) permafrost (contours of basal temperature from models extrapolated from specific boreholes, extent of lakes and water layers, thickness of permafrost from models, and specific borehole data);
- A further key effort of the group should be a permafrost drilling project to address questions such as:
- How deep are the dry-frozen materials?
- Of what importance are buried soils for interpreting and modeling environmental change?
- What are the consequences of melting of ice-cemented permafrost on global distribution and availability of water and soil genesis?
- Is there a biological signature from deep cores?
- The approach for the proposed drilling project should include:
- Drilling similar to that of NASA's program for Mars;
- Cryopedological and cryolithological studies such as geochemistry/mineralogy, isotopic analysis, etc.
- Use of GPR and other geophysical techniques;
- Use of cosmogenic and exposure dating procedures; and
- Temperature probes placed at close increments.
- The distribution of permafrost in the Andes of South America constitutes an early warning indicator of global warming on terrestrial ecosystems and warrants additional study
Coordinators
Ron Sletten, Ian Campbell, James Bockheim, D. Gilichinsky, Mauro Guglielmin, with the following subgroups:
- Terminology and identification of a legend for the permafrost map will be coordinated by Hugh French and D. Gilichinsky;
- Stephen Arcone will coordinate the permafrost database;
- Gary Clow, Alexander Kholodov, and Andrey Abramov will coordinate subglacial modeling of permafrost distribution;
- Regional (inset) permafrost map compilation will include:

- Transantarctic Mountains - James Bockheim, Ian Campbell, Bea Csatho
- Sub-Sea Permafrost - Hans Hubberten
- Drønning Maud Land - Jan Boelhouwers, Norikazu Matsuoka
