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
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?
