former Focus 4:
Polar Programs
The aim of the Polar Programs Focus was to study paleoclimate and environmental variability in polar regions. The Polar Programs focus was bipolar and included four groups: |
 |
> CAPE – Circum Arctic Paleoenvironments
Integration of paleoenvironmental research on terrestrial and adjacent margins covering the last few glacial cycles.
> QUEEN – Quaternary Environment of the Eurasian North
Mapping the extent of the last glaciation.
> ITASE – International Trans-Antarctic Scientific Expedition
Mapping the spatial variability of Antarctic climate over the last millennium.
> ANTIME – Late Quaternary Sedimentary Record of Antarctic Ice Margin Evolution
Resolution of past fluctuations in the extent and volume of the Antarctic ice sheet.
More recently, additional activities were included in this Focus, e.g., the "EPICA Challenge" to predict greenhouse gases over 800,000 years. The call for contributions was announced in Eos, two posters were presented at the 2004 AGU Fall Meeting (EPICA challenge 1 and EPICA challenge 2) and a summary paper presenting the results was again published in Eos. In 2005, PAGES initiated a new intersection program with WCRP-CliC (Climate and Cryosphere) to jointly address topics of present and past dynamics of ice sheets and sea ice, with observational (CliC) and reconstructional (PAGES) approaches.

Ongoing activities
While the old Focus 4 grouping is no longer in use, polar activities are mostly included in the new Focus 3 (Earth System Dynamics), particularly within the BIPOMAC group.
