  • Bathymetry of the core LTER lakes - From Toolik Field Station GIS.
  • Chlorophyll and Primary Production - Chlorophyll and primary production data for each lake and year for which it was collected and analyzed. Most data files appear in the format of one file for each lake during each year, but some multiple year or multiple lake sets are available
  • Nutrients -Nutrient analysis including ammonia, soluble reactive phosphorus, total dissolved nitrogen, total dissolved phosphorus, and particulate nitrogen/carbon/phosphorus, data is posted for each lake and year for which it was collected and analyzed. Most data files appear in the format of one file for each lake during each year, bust some multiple year or lake sets are available
  • Physical and Chemical Parameters - Measurements taken at every meter or half meter, including temperature, dissolved oxygen, pH, conductivity, and PAR. Also included are base cations, anion, and alkalinity for select depths
  • Fish - Capture/recapture totals, species, length, and weight of lake trout (Salvelinus namaycush), arctic grayling (Thymallus arcticus), round whitefish (Prosopium cylindraceum), burbot (Lota lota), and arctic char (Salvelinus alpinus)
  • Plankton - Zooplankton, microplankton, and picoplankton water column profiles and densities for lakes sampled during a given year
  • Bacteria - Bacterial counts and composition for Toolik Lake
  • Isotopic Values - Carbon and nitrogen isotopic signatures in biotic and abiotic samples
  • Landscape Interactions Data - Dissolved Organic Carbon, Dissolved Gasses, and Lake Met. Station Data
