Changes in carbonate chemistry measurements in the 3 CP-FOCE flumes.
Average offsets from ambient carbonate chemistry, recorded in the control, −0.06 and −0.22 treatment flumes including A) DIC and B) pH and C) calculated Ωarag in the three CP-FOCE flumes throughout the course of the 4 day experiment. ** Denote that the treatments were significantly different from the controls and each other at p<0.05.
