项目摘要

This project constructs POLENET a network of GPS and seismic stations in West Antarctica to understand how the mass of the West Antarctic ice sheet (WAIS) changes with time. The information is ultimately used to predict sea level rise accompanying global warming and interpret climate change records. The GPS (global positioning system) stations measure vertical and horizontal movements of bedrock, while the seismic stations characterize physical properties of the ice/rock interface, lithosphere, and mantle. Combined with satellite data, this project offers a more complete picture of the ice sheet's current state, its likely change in the near future, and its overall size during the last glacial maximum. This data will also be used to infer sub-ice sheet geology and the terrestrial heat flux, critical inputs to models of glacier movement. As well, this project improves tomographic models of the earth's deep interior and core through its location in the Earth's poorly instrumented southern hemisphere.

As well, this project improves tomographic models of the earth's deep interior and core through its location in the Earth's poorly instrumented southern hemisphere. Broader impacts of this project are varied. The work is relevant to society for improving our understanding of the impacts of global warming on sea level rise. It also supports education at the postdoctoral, graduate, and undergraduate levels, and outreach to groups underrepresented in the sciences. As an International Polar Year contribution, this project establishes a legacy of infrastructure for polar measurements. It also involves an international collaboration of twenty four countries.

NSF is supporting a complementary Arctic POLENET array being constructed in Greenland under NSF Award #0632320.Broader impacts of this project are varied.

该项目在南极洲西部建立了全球定位系统和地震台站网络POLENET,以了解南极洲西部冰盖的质量如何随时间变化。这些信息最终被用来预测伴随全球变暖的海平面上升,并解释气候变化记录。GPS(全球定位系统)台站测量基岩的垂直和水平运动,而地震台站则表征冰/岩石界面、岩石圈和地幔的物理特性。结合卫星数据,该项目提供了一个更完整的图片冰盖的当前状态,它可能在不久的将来变化,以及它的整体规模在最后一次冰期最大。这些数据还将用于推断亚冰盖地质和地热通量,这是冰川运动模型的关键输入。此外,该项目还通过其位于地球仪器不足的南半球的位置,改进了地球深层内部和核心的层析成像模型。本项目在南极西部建立了一个由GPS和地震台站组成的POLENET网络,以了解南极西部冰盖(WAIS)的质量如何随时间变化。这些信息最终被用来预测伴随全球变暖的海平面上升,并解释气候变化记录。GPS(全球定位系统)台站测量基岩的垂直和水平运动,而地震台站则表征冰/岩石界面、岩石圈和地幔的物理特性。结合卫星数据,该项目提供了一个更完整的图片冰盖的当前状态,它可能在不久的将来变化,以及它的整体规模在最后一次冰期最大。这些数据还将用于推断亚冰盖地质和地热通量,这是冰川运动模型的关键输入。此外,该项目还通过其位于地球仪器不足的南半球的位置,改进了地球深层内部和核心的层析成像模型。该项目的更广泛影响各不相同。这项工作与社会有关,有助于我们更好地了解全球变暖对海平面上升的影响。它还支持博士后、研究生和本科生教育,并向科学领域代表性不足的群体提供服务。作为国际极地年的贡献,该项目为极地测量建立了基础设施的遗产。它还涉及24个国家的国际合作。欲了解更多信息,请参阅IPY项目#185在IPY.org。美国国家科学基金会正在支持一个补充北极POLENET阵列正在格陵兰岛建造的美国国家科学基金会奖#0632320。这项工作与社会有关,有助于我们更好地了解全球变暖对海平面上升的影响。它还支持博士后、研究生和本科生教育,并向科学领域代表性不足的群体提供服务。作为国际极地年的贡献,该项目为极地测量建立了基础设施的遗产。它还涉及24个国家的国际合作。欲了解更多信息,请参阅IPY项目#185在IPY.org。NSF正在支持一个互补的北极POLENET阵列正在格陵兰岛建造,根据NSF奖#0632320。
