Acquisition of surveying equipment (UAVs, GNSS receivers) and associated hardware and software to support research and undergraduate training at the University of Alaska Southeast

这项地球科学仪器和设施计划奖支持购买三架用于空中地形测绘的测量级无人机(UAV)，用于相关运动结构(SfM)摄影测量处理的硬件和软件，以及用于地面测量的两个全球导航卫星系统(GNSS)接收器和天线。所要求的仪器将支持阿拉斯加东南大学的教职员工和学生的研究和研究培训。研究人员将让学生使用所需的设备进行实践学习，并积极参与公共宣传活动，讨论雪崩和冰川湖暴发、洪水危险以及气候变化对区域山区冰川的影响。阿拉斯加东南大学是阿拉斯加原住民服务机构，私人投资机构通过现有的大学课程以及与朱诺的特林吉特和海达中央委员会的联系，积极接触阿拉斯加原住民。将利用无人机绘制地形图的研究项目包括冰川-海洋相互作用、冰川湖暴发洪水、沉积和侵蚀以及雪崩动力学的基于过程的研究。野外区域将包括门登霍尔冰川。朱诺雪崩场和塔库冰川，都离大学非常近，但在阿拉斯加东南部由崎岖且基本上无法到达的地形组成。无人机和相关的GNSS基站将允许在这一具有挑战性的地形上以前所未有的精度和速度进行地形测量，以安全的方式观察快速变化的山脉冰川、冰川湖泊和雪崩易发地区，并对监测潜在危险和减少六月份的生命和基础设施损失产生直接影响。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This Division of Earth Sciences Instrumentation and Facilities Program award supports acquisition of three survey-grade unmanned aerial vehicles (UAVs) for airborne topographic mapping, hardware and software for associated Structure from Motion (SfM) photogrammetric processing, and two Global Navigational Satellite System (GNSS) receivers and antennas for ground-based surveying. The requested instrumentation will support faculty and student research and research training at the University of Alaska Southeast in Juneau, AK. The investigators will engage students in hands-on experiential learning using the requested equipment and are active in public outreach discussing avalanche and glacial lake outburst flood hazards and the effects of changing climate on regional mountain glaciers. The University of Alaska Southeast is a Native Alaskan serving institution and the PIs are active in outreach to Native Alaskans through extant University programs and through contact with the Central Council of Tlingit and Haida in Juneau. Research projects that will take advantage of the UAVs for topographic mapping include process-based studies of glacier-ocean interactions, glacier lake outburst floods, sedimentation and erosion, and avalanche dynamics. Field areas will include the Mendenhall glacier, Mt. Juneau avalanche field, and Taku glacier, all located very close to the University but comprised of rugged and largely inaccessible terrain across Southeast Alaska. The UAVs and related GNSS base stations will permit topographic surveys in this challenging terrain with unprecedented accuracy and speed to observe rapidly changing mountain glaciers, glacial lakes and avalanche prone areas in a safe manner and with direct implications for monitoring potential hazards and mitigating loss of life and infrastructure in the municipality of Juneau.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
