Manipulation

Monitoring began on lake E5 in 1999. In the year 2001 a nutrient enrichment experiment began to mimic the effects of increased nutrient availability caused by regional warming and a subsequent increase in the thaw depth of the surrounding watershed. The annual loading of both nitrogen and phosphorus were increased four fold using NH4NO3 and H3PO4 to a final annual loading of 4.0mmol N/m3 and 0.25mmol P/m3. Fertilization has continued every year and will continue through summer 2005.
