Daily summarized seasonal measurements of discharge, water temperature, and specific conductivity from Harnish Creek at F7, McMurdo Dry Valleys, Antarctica (2001-2020, 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 Harnish Creek at F7, located in the Fryxell Basin of Taylor Valley. Measurements commenced during the 2001-02 season and are ongoing. The first several seasons had either no flow or such a low flow that could not be measured. This dataset extends through the first half of the 2019-20 field season.
