Estimation of temperature change and of gas age-ice age difference, 108 kyr B.P., at Vostok, Antarctica
International audience Air trapped in ice core bubbles provides our primary source of information about past atmospheres. Air isotopic composition (lSN/•4N and 4øAr/3•Ar) permits an estimate of the temperature shifts associated with abrupt climate changes because of isotope fractionation occurring i...
