Abstract:	Soil temperature data collected every 4 hours from a wet sedge site at the Arctic Tundra LTER site at Toolik Lake. Temperatures are measured every 3 minutes and averaged every 4 hours in control, nitrogen alone, phosphorus alone, nitrogen and phosphorus, and greenhouse experimental plots soil temperatures.

Organisms studied

Methods:	Starting in June 1994 weather data has been collected in the wet sedge experimental plots (block 1) at the Arctic Tundra LTER site at Toolik Lake. Air temperature and relative humidity and soil temperatures are collected on the treatment plots: control, nitrogen alone, phosphorus alone, nitrogen plus phosphorus, shade house and greenhouse. The shade and green houses were only installed June thru August. Air temperature and relative humidity are collected every hour while soil temperatures are collected every 4 hours. Notes: Greenhouses were not covered until 4Jun98 but the sensors were up year round. Sampling Description. None
