TAXONOMIC COVERAGE:
Organisms studied

Methods:	Water samples were collected with a pump. Dissolved oxygen was measured by Winkler titration. Alaklinity was determined by acid titration to an end point of 4.8. Temperature was measured with a mercury thermometer. Oxygen isotopes in water were measured with a mass spectrometer by Dr. Lee W. Cooper, Univ. of Tennessee Knoxville. Notes: Contains some under-ice data. Oxygen isotope results are for O-18/O-16 ratios relative to the standard water (SMOW) used for isotope analyses. Negative results indicate sample is depleted in oxygen-18. Reference Citations: Some alkalinity and pH data was used in Kling et al. 1991.
