Figure 8. Changes in pCO2 on the forereef and lagoon versus the backreef.

Figure 8

Amplitude of diurnal pCO2 variation Inline graphic A) at the forereef and B) in the lagoon versus the backreef. The solid lines represent best-fit linear regressions in the form of A) y = 0.09x+12, r 2 = 0.18 and B) y = 0.89x+2.9, r 2 = 0.97 where n = 33 for both plots. The dashed lines represent 1∶1 relationships.
