I'm assessing sedimentary carbonate saturation states with respect to aragonite and was wondering if it may be worthwhile to spend some money on DIC analysis rather than measuring pH for predicting aragonite saturation states? Given that DIC is quite expensive, I was wondering if there is any available literature outlining degrees of precision of the two predictors on which to base a decision?
There is a nice discussion of uncertainty of using various combinations of parameters to describe the CO2 system in seawater in Jason Waters' recent dissertation from the University of Miami:

Much thanks Greg! I've been searching for a while now but could not find anything. Thanks for your input!
