Lake water chemistry l.jpg
Lake Water Chemistry

  • Phosphorus

  • Nitrate

  • Silica


Chemical interests l.jpg
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 l.jpg
Phosphorus

  • Total Phosphorus

    • Onondaga Very High in Hypo.

    • Green’s Mono Layer

    • Catlin and Wolf Oligotrphic





Arbutus lake nitrate l.jpg
Arbutus Lake Nitrate

  • Mostly Human Input

  • Deeper High Levels From Density Differences

  • Wolf Lakes Epi Levels High From Runoff


Silica concentrations l.jpg
Silica Concentrations

  • Concentration Effects Algal Blooms

  • Occurs From Weathering of Rocks

  • Cycle Not As Well Known As Others


Green lake silica l.jpg
Green Lake Silica

  • Very High Concentrations Compared to Other Lakes

  • Chemo and Mono Layer

  • Overall Depth


Conclusion l.jpg
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
