Daily summarized seasonal measurements of discharge, water temperature, and specific conductivity from Miers Stream at M2, McMurdo Dry Valleys, Antarctica (2014-2020, 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 Valleys' Miers Stream at the M2 streamgage, located in Miers Valley. Measurements commenced during the 2014-15 austral summer. This dataset extends through the first half of the 2019-20 field season.
