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.

阿拉斯加门登霍尔冰川（Mendenhall Glacier）长期遭受源自冰缘盆地自杀盆地（Suicide Basin）的年度溃决洪水侵扰。作为旨在解析此类洪水动力学特征及其所构成威胁的研究项目的一部分，我们采集了六类数据：(1) 无人机航空影像，用于构建被冰体封堵的该盆地的正射影像图（orthomosaics）、数字高程模型（digital elevation models）与速度场；(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）所获取的影像，用于构建正射影像图；(4) 冰川物质平衡测量数据；(5) 气象数据；(6) 自杀盆地内水体的水位测量数据。
