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

该地球科学部仪器和设施项目合同支持采购三架测量级无人机（uav），用于空中地形测绘，相关运动结构（SfM）摄影测量处理的硬件和软件，以及两个全球导航卫星系统（GNSS）接收器和天线，用于地面测量。所要求的仪器将支持位于AK州朱诺的阿拉斯加东南大学的教师和学生的研究和研究培训。研究人员将利用所要求的设备，让学生们进行动手体验式学习，并积极参与公共宣传，讨论雪崩和冰川湖溃决洪水的危害，以及气候变化对区域山地冰川的影响。阿拉斯加东南大学是阿拉斯加原住民服务机构，通过现有的大学项目和与朱诺的特林吉特和海达中央委员会的联系，pi积极与阿拉斯加原住民进行接触。将利用无人机进行地形测绘的研究项目包括基于过程的冰川-海洋相互作用研究、冰川湖爆发洪水、沉积和侵蚀以及雪崩动力学。野外区域将包括门登霍尔冰川、朱诺山雪崩场和塔库冰川，它们都位于离大学很近的地方，但由阿拉斯加东南部崎岖不平的大部分难以进入的地形组成。无人机和相关的GNSS基站将以前所未有的精度和速度在这一具有挑战性的地形中进行地形调查，以安全的方式观察快速变化的山地冰川、冰川湖泊和雪崩易发地区，并直接影响监测潜在的危险，减轻朱诺市的生命和基础设施损失。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值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.
