Manual Field Meter Stream 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. This table contains data pertaining to periodic water quality parameters measured with hand meters on streams in this region.

Methodology

Maintenance: 

The field_meter_stream table was created by Harry House in early 1994. It was first stored in an INGRES database, but was converted to ORACLE format in early 1996. Modifications were generally made each year after the initial creation in the early part of the year. It was transferred to INSTAAR in late 1997. In March, 2000, Denise Steigerwald added some variables to this file in order to make the dataset more useful in Oracle and GIS. These variables included dataset code, and strmgageid. In July, 2000, data for 1997-98, 1998-99 and 1999-2000 austral summers was added.

Additional information: 

Data collected prior to the 1993-1994 season, when the McMurdo Long-Term Ecological Research began, does not necessarily contain information for all of the sites or variables collected in subsequent years.
