本简报介绍了一种新的电子示踪剂（E-示踪剂）的首次部署，用于获得地下水文系统中的沿着流径测量。这些低成本的无线传感器平台被部署在格陵兰冰盖上的冰川穴中。在下降到冰臼之后，示踪剂穿过冰下排水系统，然后出现在冰川入口处。它们能够沿沿着流路收集从注射点到检测的数据。E-tracers发射射频信号，使传感器能够识别，定位和从冰前平原恢复。第二代原型E‐tracers记录了水压，但坚固的传感器设计提供了一个多功能平台，用于测量水文环境中的一系列参数，包括温度和电导率，这些参数使用系留传感器进行监测具有挑战性。版权所有© 2012约翰威利父子有限公司.
This briefing describes the first deployment of a new electronic tracer (E‐tracer) for obtaining along‐flowpath measurements in subsurface hydrological systems. These low‐cost, wireless sensor platforms were deployed into moulins on the Greenland Ice Sheet. After descending into the moulin, the tracers travelled through the subglacial drainage system before emerging at the glacier portal. They are capable of collecting along‐flowpath data from the point of injection until detection. The E‐tracers emit a radio frequency signal, which enables sensor identification, location and recovery from the proglacial plain. The second generation of prototype E‐tracers recorded water pressure, but the robust sensor design provides a versatile platform for measuring a range of parameters, including temperature and electrical conductivity, in hydrological environments that are challenging to monitor using tethered sensors.
