Collaborative Research: P2C2--Geothermics of Climate Change

提供资金，通过使用地球物理钻孔的温度深度剖面来开发地表温度的长期时间记录，作为限制比仪器记录更长的时间尺度上的气候变化的手段。 具体来说，研究人员将：（1）继续运行位于干旱的犹他州西北部的移民通道观测站（EPO），在那里监测气象数据和地面温度； (2) 研究俄勒冈州喀斯喀特地区气候梯度上的地面热状况和陆地-大气耦合； (3) 对选定的钻孔进行重复测井，以测试如何隔离与气候变化相关的瞬态气候事件； (4) 研究观察到的降低温度曲线的变化； （5）调查导致多代理重建和温度深度剖面得出的变暖估计差异的过程。更广泛的影响涉及强有力的教育指导部分和同样强大的智力部分。 从科学角度来看，这项研究有助于更深入地了解地表温度的温度深度重建和气候变化的多代理记录。 在教育方面，该项目将支持一名研究生，通过发展固体地球物理学和大气科学跨学科互动的定量技能，拓宽其在当代全球变化问题方面的背景。 该项目还将涉及犹他大学的研究生研究助理，NSF 支持名为 WES​​T（水、环境、科学和教学）的 GK-12 项目，由一名 PI（查普曼）领导。 WEST 学生与盐湖城学区教师和 K-12 学生互动，带领实地考察，进行实验室练习，并在当地学校建立气象站。

Funding is provided to develop long-term temporal records of ground surface temperatures by using temperature-depth profiles from geophysical boreholes as a means to constrain climate variability over timescales longer than the instrumental record. Specifically, the researchers will: (1) continue operation of the Emigrant Pass Observatory (EPO) in arid northwestern Utah where meteorological data and ground temperatures are being monitored; (2) investigate the ground thermal regime and land-atmosphere coupling across a climatic gradient in the, Cascades, Oregon; (3) repeat the logging of selected boreholes to test how to isolate the transient climate events associated with climate change; (4) investigate the observed variability in reduced temperature profiles; and (5) investigate processes leading to the discrepancy of warming estimates derived from multi-proxy reconstructions and temperature-depth profiles.The broader impacts involve a strong educational mentoring portion and an equally strong intellectual portion. Scientifically, this research could help lead to a more sophisticated understanding between temperature-depth reconstructions of ground surface temperatures and multi-proxy records of climate change. Educationally, the project will support a graduate student whose background in contemporary global change issues will be broadened by developing quantitative skills cross disciplinary interactions across the solid Earth geophysics and atmospheric sciences. The project will also involve graduate research assistants in the University of Utah, NSF supported GK-12 project titled WEST (Water, the Environment, Science, and Teaching) led by one of the PIs (Chapman). WEST students interact with Salt Lake City School District teachers and K-12 pupils, lead field trips, create laboratory exercises, and establish meteorological stations at local schools.
