I recently finished an experiment which involved using the Winkler 
method to test the dissolved oxygen content of water.  My biology 
teacher asked me to include an explanation of the chemistry behind the 
Winkler method in my lab analysis, but this information has proved 
nearly impossible to find!!  
Thanks!
