A 135,000-year Vostok-Specmap Common temporal framework

International audience The object of the present study is to introduce a means of comparing the Vostok and marine chronologies. Our strategy has been to use the •5180 of atmospheric 0 2 (denoted •518Oatm) from the Vostok ice core as a proxy for the •5180 of seawater (denoted •S18Osw). Our underlying...

Description
Summary:International audience The object of the present study is to introduce a means of comparing the Vostok and marine chronologies. Our strategy has been to use the •5180 of atmospheric 0 2 (denoted •518Oatm) from the Vostok ice core as a proxy for the •5180 of seawater (denoted •S18Osw). Our underlying premise in using •518Oatm as a proxy for •518Osw is that past variations in •5•8Osw (an indicator of continental ice volume) have been transmitted to the atmospheric 0 2 reservoir by photosynthesizing organisms in the
