Seasonal high-frequency measurements of discharge, water temperature, and specific conductivity from the Onyx River at Lower Wright, McMurdo Dry Valleys, Antarctica (1972-2020, 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 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' Onyx River at the Lower Wright streamgage, located in the Wright Valley. Measurements commenced in 1972 and are ongoing. This dataset extends through the first half of the 2019-20 field season.

Date Range: 

December 4, 1972 to January 22, 2020
