The McMurdo LTER team took control of this station during this season, and replaced it with a new station, located a few meters above the old site to avoid rising lake levels.   The station was set up to sample sensors every 30 seconds and send summary statistics (for example, averages and maximums) to solid-state storage modules every 10 minutes between December 18, 1993 and January 16, 1994, every three hours between January 16, 1994 and November 18, 1994, every 20 minutes between November 18, 1994 and November 28, 1995, and every 15 minutes thereafter.  This has resulted in approximately 20 values being recorded for final storage in every output interval.  Primary measurements made on Lake Hoare meteorology station, instrumentation used, and time of initiation are shown in the following table.   On Jan 26, 2002 a second datalogger and the TE525MM Tipping bucket rain gage was installed.  The tipping bucket records the number of tips every 15 minutes. Three soil probes, 0, 5 and 10 cm below the surface were added to the datalogger on Dec 29, 2002. Metadata Access Constraints: none Metadata Use Constraints: none annually
