Methods:
The Lake Bonney meteorology station was initially built on
the lake's ice cover in November, 1993. Shortly thereafter the station was
listed to the point where it was decided to move it to shore. Some attempt was
made to right the station during this period. The move of the station was done
using the ATV with the station still running. The move began at 14:50 and ended
at 15:06 on December 17, 1993. Data collected after 15:06 was done so with the
station in it's final position. The clock synchronized with John Priscu's logger
measuring light on Nov 26 in afternoon. 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 from November 24, 1993 to January 12, 1994,
three hours from January 12, 1994 to November 12, 1994,
20 minutes from November 12, 1994 to November 22, 1995
15 minutes thereafter.
This has resulted in approximately 28 values being recorded for final storage in every output interval.
Instrumentation:
1993-1994 - 1999-2000: Campbell Scientific 207 temp/rh probe.
1999-2000 - present: Campbell Scientific 107 temp probe.
