This award provides funds to support a study to test how well the isotopic composition of specific lipids track changes in the isotopic composition of water and dissolved inorganic carbon in lakes. The project will use analyses that require new and unproven analytical methods for measuring carbon and hydrogen isotopes on the extremely small samples involved. If successful, the project will provide a valuable new proxy measurement of isotopic compositions for paleoclimatic reconstructions.

该奖项提供资金支持一项研究，以测试特定脂质的同位素组成如何跟踪湖泊中水和溶解无机碳的同位素组成的变化。该项目将使用需要新的和未经证实的分析方法的分析，以测量所涉极小样品的碳和氢同位素。如果成功，该项目将为古气候重建提供一个有价值的新的同位素组成替代测量。
