McMurdo Dry Valleys LTER: Daily summaries of seasonal stream gage measurements from Aiken Creek at F5 in Taylor Valley, Antarctica from 1990 to present

As part of the Long Term Ecological Research (LTER) project in the McMurdo Dry Valleys of Antarctica, a systematic sampling program has been undertaken to monitor the glacial meltwater streams in that region. This package contains daily summaries derived from 15-minute measurements of water quality and quantity parameters measured with automatic recording devices on streams in this region. Specifically, this metadata record describes the daily hydrological summaries for the McMurdo Dry Valley's Aiken Stream at F5, located in the Fryxell Basin of Taylor Valley. Measurements commenced during the 1990-91 season and are ongoing. Anticipating lake level rise and the eventual submergence of the original control structure, an upstream control and streamgage was installed on 21 Dec 2011 and run simultaneously until the original control and streamgage was removed on 17 Jan 2013 at 12:52. During the period of overlap, data from the original streamgage was used for submitted data through 16 Jan 2013 12:00, afterward all data is from the upstream streamgage.

作为南极洲麦克默多干谷长期生态研究（Long Term Ecological Research, LTER）项目的一部分，本团队开展了系统性采样计划以监测该区域的冰川融水溪流。本数据集包含基于该区域溪流自动记录仪采集的15分钟间隔水质与水量参数，经处理后生成的每日汇总数据。具体而言，本元数据记录针对位于泰勒谷弗莱克塞尔盆地的F5测点麦克默多干谷艾肯溪的每日水文汇总数据进行说明。监测工作始于1990-1991年度，目前仍在持续进行。鉴于预计湖泊水位上升将最终淹没原有控制设施，项目方于2011年12月21日增设上游水文测站并同步运行，直至2013年1月17日12:52移除原有控制设施与测站。在双站同步运行期间，2013年1月16日12:00前提交的监测数据均采用原有测站的观测结果，此后所有数据均来自上游测站。
