Organisms studied

Methods:	Water samples collected at designated sites and depths in the outer lakes were analyzed on the Technicon Autoanalyzer II using Technicon methods. In addition to the Standard series run at the beginning and end of each analysis 4 standards and a blank were run with each tray of samples. Particulate Phosphorus, nitrogen and carbon samples were collected on a pre-combusted 47 mm Gelman AE filter and stored frozen until processing, Filters were then split in half and particulate phosphorus was determined using methods of Stainton et al., (1974). Notes: These were all samples that were run by Gretchen Gettel throughout the summer. Particulate phosphorus samples run by Neil Bettez in 1995 Reference Citations: R.G. Wetzel & G.E. Likens. 1979.
