I used the CO2sys program with the following S=35, t=25, Alk=11.5 mEq/L, pH(NIST)=6.8 and it gave me an omega aragonite as 0.99 and omega calcite as 1.5.

One thing with the program is the calcium concentration is fixed at 420ppm for S=35 so I would expect with the increased calcium level the omega saturation to be > 0.99?
