Organisms studied

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 following treatment plots: control, nitrogen alone, phosphorus alone, nitrogen plus phosphorus, shade house and greenhouse. Air temperature and relative humidity are read every minute and averaged every hour while soil temperatures are read every 3 minutes and averaged every 4 hours. The shade and green houses covers are only installed June thru August.

Notes: Greenhouses were not covered until early June but the sensors were up year round. Data was lost during winter 1995-1996. Relative humidity is low, never reaching above 90%. Data were not corrected.
