Daily summarized seasonal measurements of discharge, water temperature, and specific conductivity from Von Guerard Stream at F6, McMurdo Dry Valleys, Antarctica (1990-2023, 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 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 Von Guerard Stream at F6, located in the Fryxell Basin of Taylor Valley. Measurements commenced during the 1990-91 austral summer and are ongoing. The Von Guerard Stream gage (at -77.608269, 163.253853) was removed on 20 Dec 2012 due to lake level rise. A new gage upstream (at -77.609210, 163.254203) has been in use since the 2012-2013 season. This dataset extends through the first half of the 2022-23 field season.

作为南极洲麦克默多干谷长期生态研究（Long Term Ecological Research, LTER）计划的一部分，本项目已开展系统性水文采样工作，以监测该区域的冰川融水溪流。本数据包包含由该区域溪流自动记录设备采集的15分钟间隔水质与水量参数，经整理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河谷弗莱克塞尔盆地F6点位的冯·盖拉德溪（Von Guerard Stream）的每日水文汇总数据进行说明。监测工作始于1990-1991年南极夏季，且至今仍在持续进行。冯·盖拉德溪原水文监测站（坐标为-77.608269, 163.253853）因湖泊水位上升，于2012年12月20日被移除。2012-2013年监测季起，上游新建水文监测站（坐标为-77.609210, 163.254203）正式投入使用。本数据集的时间跨度覆盖至2022-2023年野外考察季的上半年。
