Ice Thickness from downstream of the EastGRIP ice core site, North East Greenland Ice Stream, recorded with the airborne AWI UWB radar system

This project aims to acquire airborne data with AWI's UWB (ultrawideband) ice-penetrating radar to extend the knowledge of detailed subglacial topography downstream of the EastGRIP ice core site, following on from a previous UWB radar survey in 2018. The ice thickness data also opportunistically includes profiles that were flown in different survey modes, both upstream and surrounding EastGRIP. The majority of profiles are oriented parallel or perpendicular to ice flow direction.本项目旨在借助阿尔弗雷德·魏格纳研究所（Alfred Wegener Institute, AWI）的超宽带（ultrawideband, UWB）冰穿透雷达（ice-penetrating radar）获取航空探测数据，以深化对东格陵兰冰芯钻探点（EastGRIP ice core site）下游区域精细冰下地形的认知，该项工作接续2018年完成的超宽带雷达勘测。此外，本次采集的冰厚数据还额外纳入了在东格陵兰冰芯钻探点上游及周边区域，以不同测量模式获取的测线剖面。绝大多数测线的走向均平行或垂直于冰流方向。
