This project tests the ability to reconstruct climate during Marine Isotope Stage 3 (MIS3) using sediments, pollen, and radioisotopic analysis of tree macrofossils recovered from a debris flow site in Oregon. Additionally, the researchers aim to explore the potential to use such logs that have measurable Carbon-14 to establish a floating chronological sequence to around 50,000 years.The primary broader impacts involve extending radiocarbon dating back more than 12,000 years in fossil logs containing tree rings for climatic analyses. The research would be done in close collaboration with the Oregon Department of Transportation and its contractors, resulting in a strong interaction between the scientists and technical and engineering experts, although it was not clear how this would advance science and engineering in the next generation. Science results would become part of an outreach effort at the university and an Oregon state exposition. Graduate students from two universities (University of Arizona and California State University at Fresno) would be part of the research.

该项目测试了利用沉积物、花粉和从俄勒冈州泥石流现场回收的树大型化石的放射性同位素分析重建海洋同位素阶段3（MIS 3）期间气候的能力。 此外，研究人员的目标是探索使用这种具有可测量的碳-14的日志来建立大约50，000年的浮动时间序列的潜力。主要的更广泛的影响包括将包含树木年轮的化石日志中的放射性碳追溯到12，000多年前，用于气候分析。这项研究将与俄勒冈州交通部及其承包商密切合作，导致科学家与技术和工程专家之间的强烈互动，尽管尚不清楚这将如何推动下一代的科学和工程。 科学成果将成为该大学和俄勒冈州博览会外展工作的一部分。来自两所大学（亚利桑那大学和加州州立大学弗雷斯诺分校）的研究生将参与这项研究。
