This project studies ancient ice buried in the Dry Valleys of Antarctica. The ice, which may approach ten million years in age, will be dated using argon and uranium radioisotope techniques. High-risk work, if successful it will offer the first and perhaps only samples of the Earth's atmosphere from millions of years in the past. These samples could offer critically important tests of paleoclimate records and proxies, as well as a glimpse into the characteristics of a past world much like the predicted future, warmer Earth. The broader impacts are graduate student education, and potentially contributing to society's understanding of global climate change and sea level rise.

该项目研究了埋葬在南极干山谷中的古代冰。冰的年龄可能接近一千万年，使用氩和铀放射性同位素技术的日期。高风险的工作，如果成功的话，它将提供过去数百万年的地球大气中的第一个，也许只有数百万年的样本。这些样本可以对古气候记录和代理进行至关重要的测试，并瞥见过去世界的特征，就像预测的未来，更温暖的地球一样。更广泛的影响是研究生教育，并有可能促进社会对全球气候变化和海平面上升的理解。
