Carbon model worksheet 2 answers
The article provides answers to the questions posed in the carbon model worksheet 2.
- (1) 282 ppm, (2) 975 ppm, (3) 1625 ppm, (4) 763 ppm, (5) 687 ppm, (6) 433 ppm (7) 429 ppm.
- No it does not return to the pre-industrial value, even after 0.2 million years. It is still 147 ppm higher.
- Initial depth of about 2.4 km. It goes shallower (ocean acidification). It takes ~62 ky to return to the original depth.
- Surface [DIC] increases from 2001 to 2439 μMol kg-1 (+438 μMol kg-1). Surface [Alk] increases from 2301 to 2720 μMol kg-1 (+419 μEquiv kg-1). Surface [CO3] increases from 209 to 211 μMol kg-1 (+2 μMol kg-1, i.e. about the same). Surface pH decreases from 8.16 to 8.07 (-0.09 units).
