Commonwealth Stream Gage Measurements

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. These tables contain data pertaining to continuous monitored water quality and quantity parameters measured with automatic recording devices on streams in this region. This metadata describes the Commonwealth Stream hydrology, starting 1993

Date Range: 

January 1, 1993 to December 31, 2015
