BSES Senior Research 2007
Background
Dissolved O2 in streams controlled by:
Primary productivity (Photosynthesis)
CO2 + H2O + sunlight CH2O + O2
Respiration
CH2O + O2 CO2 + H2O
Atmospheric exchange
Research Questions
How is primary productivity controlling water chemistry?
To what degree?
Is there a difference between shaded and open canopies?
