Intellectual Merit: UNAVCO provides NSF-funded PIs geodetic engineering, equipment, and data management and archiving services. Significant increases in polar applications of these services arose though projects funded as part of the International Polar Year. The IPY investment has stimulated a surge of more detailed scientific investigations that were not anticipated at the time when UNAVCO?s current core funding was planned. As such, these activities must be supported thought a separate proposal. Polar geodetic networks provide first order constraints on the interactions between the cryosphere, lithosphere, hydrosphere, and atmosphere, and the evolving mass balance that governs changes in global sea level and climate. In particular, these observations advance understanding of vertical deformation associated with glacial isostatic adjustment of the land surface, glacier dynamics and wasting of the ice sheets, and tectonics. The proposed terrestrial laser scanning resources will support a wide range of geoscience investigations including detailed mapping of surfaces and changes in surfaces including fault scarps, geologic outcrops, fault-surface roughness, frost polygons, lava lakes, dikes, fissures, glaciers, columnar joints and hillside drainages.Broader impacts: Polar geodetic investigations have direct relevance to changing global climate and sea level rise. Facility support for polar studies lowers the barriers for broad investigator and student involvement in these science investigations, creating infrastructure and data sets that serve broad and diverse investigator communities. The broadest impact of the project is through the university partners whose research is supported. These investigations commonly involve students and early career investigators, and thus directly support workforce development. The impact on national competitiveness, both through science contributions and on workforce development, is largely realized through UNAVCO community investigators whose students and post-docs are enabled by facility support.

知识分子优点：UNAVCO提供NSF资助的PIS GEODETIC工程，设备以及数据管理和归档服务。这些服务的极地应用大幅增加，尽管作为国际极地年份的一部分资助的项目出现了。 IPY投资激发了一系列更详细的科学研究，这些调查是在计划在UNAVCO目前计划进行核心资金时没有预料到的。因此，必须支持这些活动，这是一个单独的建议。极地测量网络对冰冻圈，岩石圈，水圈和大气之间的相互作用以及控制全球海平面变化的不断发展的质量平衡提供了一阶限制。特别是，这些观察结果提高了对与冰川等静态调整有关的垂直变形，冰川动力学和冰片浪费和构造的理解。拟议的陆地激光扫描资源将支持广泛的地球科学调查，包括表面的详细映射和表面变化，包括故障陡峭，地质露头，断层表面粗糙度，冰霜多边形，熔岩湖泊，熔岩湖，二克湖，二克，菲斯，裂缝，冰川，冰川，柱形接头和柱形接头和柱形接头和柱状关节和柱形接头和柱形接头和柱形接头和柱状，和山坡引流。BRODER的影响：极地测量研究与不断变化的全球气候和海平面上升直接相关。对极地研究的设施支持降低了广泛研究者和学生参与这些科学调查的障碍，创建了为广泛而多样化的研究者社区服务的基础设施和数据集。该项目的最广泛影响是通过支持研究的大学合作伙伴。这些调查通常涉及学生和早期职业调查人员，因此直接支持劳动力发展。通过科学贡献和劳动力发展，对国家竞争力的影响在很大程度上是通过UNAVCO社区调查人员实现的，他们的学生和职业生涯是通过设施支持来实现的。
