Daily summarized seasonal measurements of discharge, water temperature, and specific conductivity from Von Guerard Stream at F6, McMurdo Dry Valleys, Antarctica (1990-2023, ongoing)

Summary

Abstract: 

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.
