Measurements of Gases in the Vostok Ice Cores

该奖项是对一项为期两年的研究的支持，该研究旨在调查沃斯托克冰芯闭塞空气中的几种气体物种。将测量冰期和间冰期二氧化碳和甲烷碳同位素比率的差异，并应提供关于控制大气中二氧化碳和甲烷波动的机制的信息。还将测量工业化前大气二氧化碳的半球间差异，以获得有关工业化前生物源变化和假定的北半球海洋汇的信息。二氧化碳和甲烷变化的相对时间也将被研究。

This award is for support of a two year study to investigate several gas species in the air occluded in the Vostok ice cores. The glacial-interglacial difference in the carbon isotope ratios of carbon dioxide and methane will be measured, and should provide information on the mechanisms controlling carbon dioxide and methane fluctuations in the atmosphere. The pre-industrial interhemispheric difference in atmospheric carbon dioxide will also be measured to obtain information on the pre-industrial biogenic source variation and on the postulated northern hemispheric oceanic sink. The relative timing of the variations in carbon dioxide and methane will also be studied.
