合作研究 - 横贯南极山脉变形网络:南极内陆新构造运动的 GPS 测量

基本信息

项目摘要

OPP-0230285/OPP-0230356PIs: Wilson, Terry J./Hothem, Larry D.This award, provided by the Antarctic Geology and Geophysics Program of the Office of Polar Programs, supports a project to conduct GPS measurements of bedrock crustal motions in an extended Transantarctic Mountains Deformation network (TAMDEF) to document neotectonic displacements due to tectonic deformation within the West Antarctic rift and/or to mass change of the Antarctic ice sheets. Horizontal displacements related to active neotectonic rifting, strike-slip translations, and volcanism will be tightly constrained by monitoring the combined TAMDEF and Italian VLNDEF networks of bedrock GPS stations along the Transantarctic Mountains and on offshore islands in the Ross Sea. Glacio-isostatic adjustments due to deglaciation since the Last Glacial Maximum and to modern mass change of the ice sheets will be modeled from GPS-derived crustal motions together with new information from other programs on the configurations, thicknesses, deglaciation history and modern mass balance of the ice sheets. Tectonic and rheological information from ongoing structural and seismic investigations in the Victoria Land region will also be integrated in the modeling. The integrative and iterative modeling will yield a holistic interpretation of neotectonics and ice sheet history that will help us to discriminate tectonic crustal displacements from viscoelastic/elastic glacio-isostatic motions. These results will provide key information to interpret broad, continental-scale crustal motion patterns detected by sparse, regionally distributed GPS continuous trackers and by spaceborne instruments. This study will contribute to international programs focused on Antarctic neotectonic and global change issues.Strategies to meet these science objectives include repeat surveys of key sites in the existing TAMDEF network, extension of the array of TAMDEF sites southward about 250 km along the Transantarctic Mountains, linked measurements with the VLNDEF network, and integration of quasi-continuous trackers within the campaign network. By extending the array of bedrock sites southward, these measurements will cross gradients in predicted vertical motion due to viscoelastic rebound. The southward extension will also allow determination of the southern limit of the active Terror Rift and will provide a better baseline for constraints on any ongoing tectonic displacements across the West Antarctic rift system as a whole that might be possible using GPS data collected by the West Antarctic GPS Network. This project will also investigate unique aspects of GPS geodesy in Antarctica to determine how the error spectrum compares to mid-latitude regions and to identify the optimum measurement and data processing schemes for Antarctic conditions. The geodetic research will improve position accuracies within our network and will also yield general recommendations for deformation monitoring networks in polar regions.An education and outreach program is planned and will be targeted at non-science-major undergraduate students taking Earth System Science at Ohio State University. The objective will be to illuminate the research process for nonscientists. This effort will educate students on the process of science and inform them about Antarctica and how it relates to global science issues.
PI-0230285/PI-0230356:Wilson,Terry J./该奖项由极地项目办公室的南极地质和地球物理项目提供,支持一个项目,在扩展的横贯南极山脉变形网络(TAMDEF)中进行基岩地壳运动的GPS测量,以记录由于西南极裂谷内的构造变形和/或南极冰盖的质量变化而引起的新构造位移。通过监测沿着横贯南极山脉和罗斯海近海岛屿基岩GPS站的联合TAMDEF和意大利VLNDEF网络,将严格限制与活跃的新构造裂谷、走滑平移和火山活动相关的水平位移。冰川均衡调整由于末次冰盛期以来的冰消和现代质量变化的冰盖将模拟从GPS派生的地壳运动与新的信息从其他程序的配置,厚度,冰消历史和现代质量平衡的冰盖。在维多利亚陆地地区正在进行的构造和地震调查中获得的构造和流变信息也将被整合到建模中。综合和迭代建模将产生一个整体的解释新构造和冰盖的历史,这将有助于我们区分构造地壳位移粘弹性/弹性冰川均衡运动。这些结果将提供关键信息,以解释由稀疏的、区域分布的全球定位系统连续跟踪器和星载仪器探测到的广泛的大陆尺度地壳运动模式。这项研究将有助于关注南极新构造和全球变化问题的国际计划。实现这些科学目标的战略包括对现有TAMDEF网络中的关键站点进行重复调查,将TAMDEF站点阵列沿着横贯南极山脉向南延伸约250公里,与VLNDEF网络进行关联测量,以及将准连续跟踪器集成到活动网络中。通过向南延伸基岩场地的阵列,这些测量将跨越由于粘弹性回弹而预测的垂直运动的梯度。向南的延伸还将有助于确定活动的恐怖裂谷的南部界限,并将提供一个更好的基线,以限制整个西南极裂谷系统任何正在发生的构造位移,这可能是使用西南极全球定位系统网络收集的全球定位系统数据所能做到的。该项目还将调查南极全球定位系统大地测量的独特方面,以确定误差谱与中纬度地区相比如何,并确定适合南极条件的最佳测量和数据处理方案。大地测量研究将提高我们的网络内的位置精度,也将产生在极地地区的变形监测网络的一般性建议。一个教育和推广计划的计划,将针对非科学专业的本科生在俄亥俄州州立大学地球系统科学。目的是为非科学家阐明研究过程。这项工作将教育学生了解科学进程,并向他们介绍南极洲及其与全球科学问题的关系。
