Organisms studied

Methods:	Water, physics and chemistry sampled weekly from central station the main station on Toolik Lake Temperature and conductivity were read by the YSI model 33, conductivity meter. Dissolved O2 and Temperature were read by YSI model 57 oxygen meter, air calibrated. Carbonate alkalinity was titrated against pH depending on expected alkalinity (see Wetzel and Likens 1979). pH was measured electrometrically with a Corning portable expanded standard pH buffer and corrected for temperature of sample. Notes: Not all data is available for all years. Reference Citations: R.G. Wetzel & G.E. Likens. 1979. Limnological Methods. Saunders. Philadelphia. Sampling Description. None
