LeConte Glacier Unmanned Aerial Vehicle (UAV) imagery, LeConte Glacier, Alaska, 2018

Between September 1 and September 18, 2018, we conducted field measurements at LeConte Glacier, Alaska, to study the impacts of subglacial discharge on plume dynamics and submarine melting. From September 13 to September 17, we used a UAV (Unmanned Aerial Vehicle) quadcopter to capture vertical and oblique aerial images of the LeConte terminus. Over this five day period, we conducted 2-3 campaigns per day, resulting in 12 campaigns overall. The aerial images are used to measure ice elevation and velocity at the LeConte terminus.

2018年9月1日至9月18日，我们在阿拉斯加州的莱孔特冰川（LeConte Glacier）开展野外实地测量，以研究冰下径流对羽流动力学及海底消融的影响。2018年9月13日至9月17日期间，我们使用四旋翼无人机（Unmanned Aerial Vehicle，UAV）采集了莱孔特冰川前端的垂直与倾斜航空影像。在这五天的观测周期内，我们每日开展2至3次测量作业，累计完成12次测量作业。所获取的航空影像可用于测定莱孔特冰川前端的冰面高程与运动速度。
