Comparison of CO2 measurements by two laboratories on air from bubbles in polar ice ...
The CO2 content of air enclosed in bubbles in polar ice has been reported by our two laboratories (in Grenoble and Bern) to be representative of the atmospheric CO2 concentration at the time the ice was formed (1,2). Such ice core studies indicate lower concentrations in ice formed at the end of the...

The CO2 content of air enclosed in bubbles in polar ice has been reported by our two laboratories (in Grenoble and Bern) to be representative of the atmospheric CO2 concentration at the time the ice was formed (1,2). Such ice core studies indicate lower concentrations in ice formed at the end of the ice age, around 18,000 yr BP, and several explanations have been proposed for such a change (3,4). Both laboratories are currently measuring various ice cores in order to determine the pre-AD 1850 CO2 level in the atmosphere, which relates to the partitioning of anthropogenic CO2 among the atmospheric, biospheric and oceanic reservoirs. The two laboratories use different ice cores and different analytical procedures and we, therefore, need to know to what extent the measurements are quantitatively comparable. We present here the results of a comparison between the two laboratories based on measurements from the same ice core sections, which indicate that the measurements can be compared with great confidence.
