US-Jordan Cooperative Research: Borehole Paleoclimatology and Heat Flow in Jordan

描述：该奖项是为了支持北达科他州大福克斯北达科他州大学的William Gosnold教授和约旦安曼自然资源管理局地球物理部的Abdallah Al-Zoubi博士的合作项目。他们计划在约旦进行探索性研究，在现有的钻孔中进行地热测量，用于采矿和石油钻探等目的。然后，这些数据将用于确定来自地壳的地球热通量，并重建过去500-1000年的地表温度历史。地下温度对我们了解地球表面的气候历史、岩石圈的构造-热结构和演化具有重要意义。了解约旦不同地方的陆地热通量有可能揭示死海裂谷的构造发展，作为更大的红海裂谷系统的一部分。该地区过去一千年的古气候可能有助于解释该地区从地中海气候到沙漠气候的空间转变。科学家们将评估数据质量，以确定通过全面合作研究项目进行广泛数据收集的可行性。范围：在这个项目中，合作者计划结合他们的专业知识来探索利用现有钻孔进行古气候学和热流测量的合理性。这两位科学家的专长互补。美国PI在钻孔测量和古气候学方面经验丰富。这位约旦科学家在实地研究领域有经验，并在该领域发表了大量出版物。美国PI将包括一名来自美国北达科他州的研究生进行实地研究，从而为他提供国际研究环境的经验。该项目符合国际情报机构支持互利合作项目的标准。

0138475GosnoldDescription: This award is for support of a cooperative project by Professor William Gosnold, University of North Dakota, Grand Forks, North Dakota and Dr. Abdallah Al-Zoubi of the Geophysics Department of the Natural Resources Authority, Amman, Jordan. They plan to conduct exploratory research in Jordan by making geothermal measurements in existing boreholes, made for purposes such as mining and oil drilling. These data would then be used to determine the terrestrial heat flux from the crust, and to reconstruct the ground surface temperature history for the past 500-1000 years. Subsurface temperature bears importance to our understanding of the climate history at the Earth's surface and the tectono-thermal structure and evolution of the lithosphere. Understanding the terrestrial heat flux at various places in Jordan has the potential to shed light on the tectonic development of the Dead Sea Rift, as a part of the larger Red Sea rift system. The paleoclimate of the area over the past millennium may help explain the spatial transition from Mediterranean climate to desert climate in this region. The scientists will assess data quality to determine the feasibility of making extensive data collection through a full-scale collaborative research project.Scope: In this project the collaborators plan to combine their expertise to explore the soundness of using existing boreholes to make paleoclimatology and heat flow measurements. The two scientists have complementary expertise. The US PI is experienced in borehole measurements and in paleoclimatology. The Jordanian scientist has experience with the field research area and has produced strong publications on that area. The US PI will include a graduate student from U. North Dakota in the field research thus giving him experience in an international research setting. The project meets INT criteria for support of cooperative projects that are mutually beneficial.
