model, Eqs. C.3 and C.14 were ignored, index 1 was replaced by index a, *y was 

 added to the right-hand side of the equation for the lower atmosphere 

 (Eq. C.17), and Ai u and *Ai u were set equal to zero. For the three-reservoir 

 model, Eqs. C.4, C.5, C.15, and C.16 were also ignored, and A lb , Ai e , *A le , and 

 *Aj e were also set equal to zero. 



For calculations of inactive carbon, if these included prediction beyond 

 1969, the following replacements were made in the perturbation equations to 

 restore the expressions for the land biota to their original form as given in 

 Appendix A-. A\^ was replaced by 



and Ai e was replaced by 



APPENDIX D: EVALUATION OF SURFACE OCEAN EVASION FACTOR 



Stoichiometric equilibrium quotients are defined as follows: 



Ko = !^i! cd.i) 



K B = [H+][B(0H 1 )4] (D.4) 



B [B(OH) 3 ] 



K w = [H + ] [OH - ] (D.5) 



where brackets denote concentrations in moles per liter of seawater. 



The quotients were evaluated for average ocean surface water with tempera- 

 ture 19.59°C (T= 292.75°K) and chlorinity (Cl) 19.24 per mil. Equations for 

 the equilibrium quotients in seawater are 5
