Mean Daily Stream Gage Measurements 1969-1997

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 table contains data pertaining to means obtained from continuously monitored water quality and quantity parameters. Measurements were taken from automatic recording devices on streams in this region. This dataset contains daily means for the stream gage measurements during the period 1969-1997.
