Raw Ground Penetrating Radar Data, Eklutna Glacier, Alaska; 2013

Common-offset GPR surveys were conducted with a Sensors and Software 500-MHz Pulse Ekko Pro system. We collected data from the ground, towed behind a researcher on skis or snowmobile, and from the air, strapped underneath a helicopter. All of the profiles are linked to coincident GPS observations. Coincident in-situ data is provided for calibration, and may be composed of any of the following: snow pits and/or snow-pit/snow-core combinations, probe profiles, and ablation stakes. This supplemental information may be used to calibrate velocity for conversion from time domain to depth domain. This supplemental information is provided as is, with additional information specific to usage included within the in-situ folder.本数据集采用传感器与软件（Sensors and Software）公司的500 MHz脉冲Ekko Pro探地雷达（Ground Penetrating Radar, GPR）系统开展共偏移距探地雷达测量。数据采集方式包括地面定点采集、由研究人员身着滑雪装备或乘坐雪地摩托牵引的移动地面采集，以及挂载于直升机下方的航空采集。所有测线数据均与同步GPS观测数据关联。本次研究附带同步原位（in-situ）校准数据，该类数据可由以下任意一项或多项组成：雪坑、雪坑/雪芯组合、探杆剖面数据以及消融标桩数据。该补充数据可用于校准雷达波传播速度，以实现探地雷达数据从时域到深度域的转换。本补充数据按现状提供，其使用相关的额外说明已包含在原位数据文件夹中。
