Data file describing the biogeochemistry of samples collected at various sites near Toolik Lake on the North Slope of Alaska. Sample site descriptors include a unique assigned number (sortchem), site, date, time, depth, and category (level of thermokarst disturbance). Physical measures collected in the field include temperature, electrical conductivity, and pH. Chemical analyses include alkalinity; dissolved organic carbon (DOC); inorganic and total dissolved nutrients (NH4, PO4, NO3, TDN, TDP); particulate carbon, nitrogen, and phosphorus (PC, PN, and PP); cations (Ca, Mg, Na, K); anions (Cl, SO4); and silica. A synthesis of much of the data presented here is published in Cory et al. 2013, PNAS 110:3429-3434; Cory et al. 2014, Science 345:925-928; and Page et al. 2013, Environment, Science, & Technology 47:12860−12867.
