Abstract
Polar ice sheets are proving richer sources of information about past atmospheric conditions than any other sequency of Quaternary sediments. All kinds of fall-out from the atmosphere, such as air-borne continental dust and biological material, volcanic debris, sea salts, cosmic particles, and cosmic ray produced isotopes, are deposited on the ice sheet surfaces along with the snow. The snow pack is gradually compressed into solid ice with small cavities containing samples of atmospheric air. In the coldest areas of the ice sheets, the impurities remain in the ice as indicators of the chemical and physical conditions of the atmosphere at the time of deposition.
