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. 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. 1969-01-01 1997-12-31 ground condition The mean_daily_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.
