Problem
This figure shows the distribution of dissolved oxygen with depth in several lakes.
1) What would you predict the productivity levels to be in Atter Lake (with an orthograde profile)?
2) Why would you make this prediction?
3) What would you predict the productivity to be in Oberturner Lake (with a clinograde profile)?
4) Why would you make this prediction?
5) What conditions would promote the positive or negative heterograde profiles observed in Worther Lake or Osslacher Lake?
