Mendenhall Glacier / Suicide Basin outburst flood data, 2018-2019

Mendenhall Glacier, Alaska, has been experiencing annual outburst floods that originate from Suicide Basin, an ice marginal basin. As part of a project aimed at understanding the dynamics of these floods and the threat that they pose, we collected (1) aerial imagery from an unmanned aerial vehicle that was used to construct orthomosaics, digital elevation models, and velocity fields of the ice-choked basin, (2) LIDAR data that was used to construct additional digital elevation models, (3) photos from the Alaska High-Altitude Aerial Photography project (AHAP) that was used to construct an orthomosaic, (4) glacier mass balance measurements, (5) meteorological data, and (6) water level measurements of the water in Suicide Basin.

阿拉斯加的门登霍尔冰川（Mendenhall Glacier）持续发生源自自杀盆地（Suicide Basin，一处冰缘盆地）的年度溃决洪水。作为一项旨在解析此类洪水动力学机制及其所构成威胁的研究项目的组成部分，本研究共采集了六类数据集：1. 无人机（unmanned aerial vehicle, UAV）航拍影像：用于构建该冰塞盆地的正射影像镶嵌图、数字高程模型与流速场；2. 激光雷达（LIDAR）数据：用于构建补充性数字高程模型；3. 阿拉斯加高空航空摄影项目（Alaska High-Altitude Aerial Photography, AHAP）的航拍照片：用于构建一幅正射影像镶嵌图；4. 冰川物质平衡测量数据；5. 气象观测数据；6. 自杀盆地内部水体的水位测量数据。
