Landscape Interactions Data

  • Chemistry Files - includes soil water and surface water chemistry.   Data include temperature, pH, conductivity, dissolved gases (CO2 and CH4), dissolved organic and inorganic carbon (DOC and DIC), alkalinity, inorganic and total dissolved nutrients (NH4, PO4, TDN, TDP), particulate organic nitrogen and carbon (PON and POC), Chlorophyll a, and major and minor ions.
  • Lake Climate Station Files - includes data from lakes E5 and Toolik by year.  Both stations measure wind speed and direction, air temperature, and humidity.  The Toolik lake station also measures net longwave and shortwave radiation.
  • Discharge - Measured at the Tussock Watershed weir and at the Toolik Lake Inlet, and organized by year.
  • Bacterial Production Files - Bacterial productivity data for various lakes and streams near Toolik Lake.
  • Watershed Thaw Survey - Thaw depth measurements were measured weekly to biweekly during the summer season, June to late August.
