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.

该奖项是为了支持一项为期两年的研究， 空气中的几种气体被东方号冰芯所封闭。 冰川-间冰期沉积物碳同位素比值的差异 二氧化碳和甲烷将被测量， 关于控制二氧化碳的机制的信息， 甲烷在大气中的波动 工业化前 大气中二氧化碳的半球间差异也将 以获得关于工业化前生物 源的变化和对假定的北方海洋 水槽 二氧化碳变化的相对时间， 还将研究甲烷。
