GLeon Ad hoc Mendota Modeling Researchers

3. Timeline
July 2009: Diverse group of modelers, physical limnologists, ecologists, and microbiologists descend on Trout Lake Station for one week
5 days later…. Mendota is modeled
Fall 2009: calibrate, validate, and explore science questions

4. DYRESM CAEDYM ELCOM CAEDYM
DYRESM (1D) or ELCOM (3D) with CAEDYM
2008 GLEON meteorological and water quality driver data
NTL LTER chemical and biological data
USGS
DYRESM is a 1D hydrodynamic model predicting temperature, salinity and density- computational requirements modest
ELCOM is a 3d hydrodynamic model

6. Science Questions
What are the primary controls on cyanobacterial bloom dynamics?
Which features of model output can inform our understanding of microbial community dynamics?
Emergent properties of the model?

7. More Questions… Lake-wide responses to long-term climate change
How will trophic cascade respond to fluctuations in climate?
Are lakes Ahrrenius?
Metabolic theory of ecology?
System level feedbacks might make the ecosystem behave differently than we expect?
Toxin genes related to stoichiometry
Toxin genes related to toxin concentration
