Seasonal high-frequency measurements of discharge, water temperature, and specific conductivity from Aiken Creek at F5, McMurdo Dry Valleys, Antarctica (1990-2019, ongoing)

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 data pertaining to continuous monitored water quality and quantity parameters measured with automatic recording devices on streams in this region. Specifically, this metadata record describes the hydrology data set for the McMurdo Dry Valleys' Aiken Stream at the F5 streamgage, located in the Fryxell Basin of Taylor Valley. Measurements commenced during the 1990-91 season. 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. This dataset extends through the 2018-19 field season.作为南极洲麦克默多干谷（McMurdo Dry Valleys）长期生态研究（Long Term Ecological Research, LTER）项目的一部分，本项目已开展系统性采样计划，对该区域的冰川融水溪流进行监测。本数据包涵盖通过自动记录设备在该区域溪流上测得的连续水质与水量监测参数相关数据。具体而言，本元数据记录针对位于泰勒谷（Taylor Valley）弗莱克塞尔盆地（Fryxell Basin）的F5溪流测站（F5 streamgage）所辖的麦克默多干谷艾肯溪（Aiken Stream）水文数据集进行说明。监测工作始于1990-1991年度野外考察季。鉴于湖泊水位上升将最终导致原有监测控制设施被淹没，项目方于2011年12月21日增设了上游监测控制设施与溪流测站，并与原有设施同步运行，直至2013年1月17日12:52移除原有监测控制与溪流测站设施。在双站并行运行期间，2013年1月16日12:00之前提交的监测数据均来自原测站，此后所有数据均取自上游测站。本数据集的覆盖时段延伸至2018-2019年度野外考察季。
