CaCO3 dissolution: new vs. tried & true

I couldn't agree more with Ray regarding the use of a "new" scheme.  If we
were to make the standard OCMIP-2 run with a new scheme for CaCO3 cycling,
we would surely have some nasty surprises. 

As for sensitivity studies by individual groups, that is a fine idea, as I
expressed in San Diego.  However, I do not believe we should wait for
results from sensitivty runs, which could take many months, before
finalizing protocols and getting all groups started to make the standard
run for OCMIP.  In other words, I would suggest following the example of
NASA, who didn't use cutting edge technology to put men on the moon
because such an approach was considered neither reliable nor efficient.
