随着大量的水通过蒸发被抽离，并以雪的形式沉淀形成冰川冰，海洋中氧同位素的比率就发生了变化。
The oxygen isotope ratio of the ocean changes as a great deal of water is withdrawn from it by evaporation and is precipitated as snow to form glacial ice.
研究人员对间冰期气候的线索来自保存在 GRIP 冰芯中的两种略微不同类型的氧——即同位素氧-16和氧-18的比率。
Researchers' clues to the Eemian climate come from measurements of the ratios of two slightly different types of oxygen, isotopes oxygen-16 and oxygen-18, preserved in the GRIP core.
他们然后使用当地的降雪记录来寻找有气象记录的年代里降雪量和树木年轮中氧元素同位素的比率之间的关系。
They then used local snowfall records to find the relationship between precipitation and the proportion of heavy oxygen in tree rings for the years covered by the weather records.
