TAXONOMIC COVERAGE:
Organisms studied

Methods:	Water samples were collected with a Van Dorn Bottle or a pump. Dissolved oxygen was measured by Winkler titration. Alkalinity was determined by acid titration to an end point of 4.8. Sulfate measurements were made using ion chromatography. Ammonia and nitrate were determined using flow injection colorimetric methods. Temperature measured with a mercury thermometer. Methane was measured by gas chromatography. Notes: Contains some under-ice data. Reference Citations: Some alkalinity and pH data was used in Kling et al. 1991.
