Estimating Eh from DO

Hi Dave-
 
Sorry to bother you, I know you are busy...
 
I have been searching for a straightforward calculation to estimate Eh from DO in oxgenated surface waters - I stumbled across your Phreeqe IAQ but did not find the specific question answered.  I have field measured T, pH, but had the redox electrode go whack on me. 
 
Do you have a simple formula or can you provide me a reference where it can be obtained?
 
Appreciate your help!
 
Doug
