Pliocene and Pleistocene Climatic Change in South-Central Colorado

欧洲大陆地区的气候历史 地球表面不如海洋地区那么为人所知。 沉积的不连续性限制了我们获取 大陆的气候记录。 过去的长记录 大陆性气候非常罕见。 这项建议 请求支持重建2010年气候历史， 科罗拉多中南部最后5 Ma。 使用的样本来自130 米钻芯，PI将使用古地磁和火山灰层 为核心提供时序控制，并将重建 从孢粉学和古生物学代用资料看过去气候 指标 该项目的目标是将气候 在这个地区观察到的变化与气候的历史， 记录在海洋生物的氧同位素组成中 沉积物 这项研究很重要，因为它将把 上新世以来的海洋和陆地气候记录， 地球历史的更新世间隔。 这一项目的 支持ROW/RIA计划。

The history of climate above the continental regions of the earth's surface is less well-known than above oceanic regions. Discontinuities in sedimentation limit our ability to acquire records of climate on the continents. Long records of past continental climate are particularly rare. This proposal requests support to reconstruct the history of climate for the last 5 Ma in south-central Colorado. Using samples from a 130 meter drill core, the PIs will use paleomagnetics and ash layers to provide chronologic control for the core and will reconstruct past climate from palynological and paleontological proxy indicators. The goal of the project is to correlate the climatic changes observed in this region with the history of climate as it is recorded in the oxygen isotopic composition of marine sediments. This research is important because it will link the marine and terrestrial records of climate from the Pliocene and Pleistocene intervals of earth history. This project is being supported under the ROW/RIA program.
