The high CO2 concentration of 318 mmol L−1 measured from CTD 13?7 (Figure 2) had a pH of 6.8 ? 0.2. A pH value of 6.8 corresponds to calculated values of about 9000 ppm CO2 in dry air and a CO2(aq) value of about 320 mmol L−1. Slight reduction of pH in North Sea waters has been seen where respiration takes place, and annual cycles of pH vary between 7.8 and 8.4 depending on the distance to the coast
The ipcc like to focus on peguins, polar bears and coral for impact. How much Co2 is naturally bubbling up globally as bubbles dissolve very rapidly (within meters). How can you model off the unknown as there is very little known about natural CO2 seepage.
