  2. BREAKDOWN • Mike- P levels • Marvel- effects on organisms • Rich- lake wide/cumulative

  3. Limnology Lab Data ReviewWater Chemistry-Phosphorus • Comparison of total P among the six lakes sampled during the Fall 2004 Semester • Total P and Dissolved P in the three Adirondacks Lakes sampled • Sources and effects of phosphorus

  4. Expectations • High P levels = high production • High P levels = increased phytoplankton ** • High P levels = increased light attenuation • High P environments = increased amphipod/copepod populations -presence of some indic. of P

  5. Comparison of total P in the five lakes sampled

  6. Total and Dissolved P in Arbutus Lake

  7. Total and Dissolved P in Catlin Lake

  8. Total and Dissolved P in Rich Lake

  9. Correlation Cat Rich Arb P chl

  10. What are the sources of phosphorus • Anthropogenic • Onondaga Lake – Sewage • Oneida Lake – Agricultural runoff • Iron Trap?

  11. What are the effects of phosphorus ? • On phytoplankton ? • On fish?
