Clipper Pit Lake Profile 8-1-17

Residual pit lakes from mining are often dangerous to sample for water quality. Thus, pit lakes may be rarely (or never) sampled. This study developed new technology in which water-sampling devices mounted on an unmanned aerial vehicle (UAV) were used to sample five pit lakes in Nevada, USA during one week in 2017. Three of these pit lakes are located on public lands and two are located on private land owned by mining entities. A profile was taken of the Clipper pit lake with a conductivity, temperature and depth profiler on August 1, 2017. This approach can potentially incorporate the use of additional multi-parameter probes: pH, oxygen concentration, turbidity and chlorophyll. Some limitations of this UAV water sampling methodology are battery duration, weather conditions and payload capacity.采矿活动遗留的矿坑湖在开展水质采样作业时往往具有较高危险性，因此此类矿坑湖极少甚至从未被采样。本研究开发了一项新型采样技术：将水质采样装置搭载于无人驾驶飞行器（Unmanned Aerial Vehicle, UAV）之上，并于2017年的一周内，在美国内华达州完成了5处矿坑湖的采样工作。其中3处矿坑湖位于公共用地，剩余2处隶属于矿业主体所有的私有土地。2017年8月1日，研究人员使用电导、温度与深度剖面仪对克利珀矿坑湖进行了剖面测量。该方法可拓展集成更多多参数探测探头，涵盖pH值、溶解氧浓度、浊度与叶绿素检测模块。该无人机水质采样方法存在若干局限性，主要包括电池续航时长、气象条件以及有效载荷容量限制。
