Lake Water Chemistry • Phosphorus • Nitrate • Silica
Chemical Interests • Lake Production • Levels Often Predict Entire Food Web • Direct Effects on Spec. Cond., D.O., etc. • Biotic Composition • Direct/Indirect Relationships • Visual Effects
Phosphorus • Total Phosphorus • Onondaga Very High in Hypo. • Green’s Mono Layer • Catlin and Wolf Oligotrphic
Arbutus Lake Nitrate • Mostly Human Input • Deeper High Levels From Density Differences • Wolf Lakes Epi Levels High From Runoff
Silica Concentrations • Concentration Effects Algal Blooms • Occurs From Weathering of Rocks • Cycle Not As Well Known As Others
Green Lake Silica • Very High Concentrations Compared to Other Lakes • Chemo and Mono Layer • Overall Depth
Conclusion • Several Factors Effect the Concentrations of Chemicals Found Within a Lake. • Catchment • Physical Features • Paleolimnology • Anthropogenic Influences • Each of These Factors Then Effects The Rest of The lakes Biotic and Abiotic Features
