Collaborative Research: P2C2: Terrestrial Late Pleistocene Paleoenvironment Back to MIS 3 from Fossil Microflora & Tree Rings in Recent Excavated Landslide Deposits, Western Or

该项目使用沉积物、花粉和从俄勒冈州泥石流现场发现的树木宏观化石进行放射性同位素分析，测试了在海洋同位素第三阶段(MIS3)期间重建气候的能力。此外，研究人员的目标是探索使用这种含有可测量的碳-14的原木来建立一个浮动的时间序列到大约5万年的可能性。主要的更广泛的影响包括将含有树木年轮的化石原木中的放射性碳追溯到12000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科学和工程。科学成果将成为该大学外展活动和俄勒冈州博览会的一部分。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。

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.
