Antarctic surface temperature and elevation during the Last Glacial Maximum

The Antarctic Vostok ice core provided compelling evidence of the nature of climate, and of climate feedbacks, over the past 420,000 years. Marine records suggest that the amplitude of climate variability was smaller before that time, but such records are ...

One-to-one coupling of glacial climate variability in Greenland and Antarctica

Jérôme Chappellaz, Matthew Davis

The recent completion of drilling at Vostok station in East Antarctica has allowed the extension of the ice record of atmospheric composition and climate to the past four glacial-interglacial cycles. The succession of changes through each climate cycle and ...

Recovery of the locomotor function after prolonged microgravity exposure. I. Head-trunk movement and locomotor equilibrium during various tasks

Grégoire Courtine

Recovery of locomotor function was investigated in seven cosmonauts exposed to microgravity for 6 months. Crew members executed a locomotor task with visual cues (eyes open, EO) and without them (eyes closed, EC). The locomotor task consisted of ascending ...

Atmospheric methane during the last four glacial-interglacial cycles: Rapid changes and their link with Antarctic temperature

Jérôme Chappellaz

Samples of air at various depths in firn were collected at Vostok Station, Antarctica, and analyzed for δ15N of N2, O2/N2 ratio, and CO2. The ultimate objective of this work is to constrain the recent rate of the atmospheric [O2] decrease, thereby providin ...

Changes in the O2/N2 ratio of the atmosphere during recent decades reflected in the composition of air in the firn at Vostok Station, Antarctica

Jérôme Chappellaz

Analysis of air trapped in polar ice provides the most direct information on the natural variability of Greenhouse Trace Gases (GTG). It gives the context for the dramatic change in their atmospheric concentrations induced by anthropogenic activities over ...

The atmospheric CH4 increase since the Last Glacial Maximum: (1). Source estimates

Jérôme Chappellaz

The Vostok core provides the longest ice record of past climatic and environmental conditions, extending back to the interglacial Marine Isotope Stage (MIS) 11, around 400 kyr ago. The MIS 11 information obtained from different time series at Vostok, namel ...

Synchronous changes in atmospheric CH4 and Greenland climate between 40 and 8 kyr BP

Air trapped in ice core bubbles provides our primary source of information about past atmospheres. Air isotopic composition (15N/14N and 40Ar/36Ar) permits an estimate of the temperature shifts associated with abrupt climate changes because of isotope frac ...
