Vocabulary:  Eutrophication: is a natural process; where lakes, as they age, build up nutrients which cause phytoplankton to grow.  Phytoplankton: Microscopic.

Eutrophication What is it?. Eutrophication begins when nutrients such as nitrates and phosphates run off into a body of water.

Mike- P levels Marvel- effects on organisms Rich- lake wide/cumulative

Limnology Lab Data Review Water 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

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

Comparison of total P in the five lakes sampled

Total and Dissolved P in Arbutus Lake

Total and Dissolved P in Catlin Lake

Total and Dissolved P in Rich Lake

Correlation

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

What are the effects of phosphorus ? On phytoplankton ? On fish?
