Abstract:
Polar snow and ice are among the most valuable, or perhaps are the most valuable, tools for reconstructing past climatic conditions. Glacial‐ice records large changes over time scales ranging from intraannual to glacial‐interglacial transitions. Changes in the ice are thought to largely reflect changes in atmospheric chemistry and dynamics resulting from variations in biogeochemical cycling due to climatic, and other, perturbations [ Oeschger and Langway , 1989]. However, two broad classes of processes, air‐to‐snow transfer and post‐depositional modification, combine to filter and potentially distort atmospheric signals before they can be preserved in the glacial record [ Neftel , 1991]. Recognizing the critical need to understand air‐snow transfer and postdepositional modifications to unravel the climate information recorded in ice cores, the International Commission on Snow and Ice (ICSI) established a working group on Snow‐Atmosphere Chemical Exchange. With support from the National Science Foundation, Division of Polar Programs, the ICSI working group organized a workshop to develop a science plan for a 3‐ to 5‐year research effort focused on exchange processes. The workshop will follow the current Greenland Ice Sheet Project Two (GISP2) drilling effort at Summit, Greenland.
