The results of many years of Russian‐French‐American studies of an ice core from a borehole in central Antarctica to a depth of 3310 m are presented. The data encompass four climatic cycles over the course of 420,000 years. The similarity and dif

The results of processing of an ice core to a depth of 2,755 m, which encompasses the last two climatic cycles, are examined. Data on deuterium content in the ice are analyzed, as are paleotemperature, content of continental dust in the ice, and chan

A new ice core drilled at the Russian station of Vostok in Antarctica reached 2755 m depth in September 1993. At this depth, the glaciological time scale provides an age of 260 ky BP (±25). We refine this estimate using records of dust and deuterium

We have studied the levels of 14C in firn and ice from two regions accumulating ice in Antarctica, Dome C, and Newall Glacier. The observed concentrations indicate variable amounts of in-situ 14C from cosmic-ray spallation of oxygen. 14C appears to b

Climatic conditions of the Penultimate Ice Age are analyzed on the basis of isotopic‐geochemical analyses of an ice core from the Vostok Antarctic research station. Data from the core, which includes material from as deep as 2546 m, permits the com

The Russian Vostok Station is located on the high Antarctic plateau, at 78°29′S, 106°49′E, in one of the most remote parts of the world. Vostok Station was established in 1957 during the International Geophysical Year (IGY), and ice-drilling ac

The prediction of future greenhouse-gas-warming depends critically on the sensitivity of earth's climate to increasing atmospheric concentrations of these gases. Data from cores drilled in polar ice sheets show a remarkable correlation between past g

Methane measurements along the Vostok ice core reveal substantial changes over the past 160,000 years which are associated with climate fluctuations. These results point to changes in sources of methane and also show that methane has probably contrib

Deuterium content, microparticle concentration, ice crystal size and bubble concentration have been studied along an 82 m ice core drilled down to the bedrock in the ice-sheet margin in East Antarctica. The Last Glacial Maximum (LGM) is distinctly ma

A climatic record given by isotopic composition of ice from Dome C (Antarctica) is studied using evolutive spectral analysis by AR process. Problems which occur when trends and non periodic accidents are present in the signal are examined. Experiment
