Seasonal high-frequency measurements of discharge, water temperature, and specific conductivity from the Onyx River at Lake Vanda, McMurdo Dry Valleys, Antarctica (1969-2023, 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 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 Lake Vanda streamgage, located in the Wright Valley. Measurements commenced in 1969 and are ongoing. This dataset extends through the first half of the 2022-23 field season.

Date Range: 

December 5, 1969 to January 20, 2023
