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.

这个项目研究埋藏在南极洲干旱山谷的古代冰。这些冰的年龄可能接近1000万年，将使用氩和铀放射性同位素技术测定其年代。这项高风险的工作，如果成功的话，它将提供第一个，也许是唯一一个数百万年前地球大气层的样本。这些样本可以提供至关重要的古气候记录和代理测试，以及对过去世界特征的一瞥，就像预测的未来一样，更温暖的地球。更广泛的影响是研究生教育，并可能有助于社会对全球气候变化和海平面上升的理解。
