Organisms studied

Starting in June 1994 weather data was collected with a Campbell CR10 data logger in the wet sedge experimental plots at the Arctic Tundra LTER site at Toolik Lake. Air temperature and relative humidity and soil temperatures were collected on the treatment plots. The treatments included: control, nitrogen alone, phosphorus alone, nitrogen plus phosphorus, shade house and greenhouse. The shade and greenhouses were only installed June thru August.

Notes: Greenhouses were not covered until 4Jun98 but the sensors were up year round. The data logger stopped collecting data from Feb through May. The temperature and RH sensors failed from May to August due to a faulty splice in the cable.
