solubility pump runs for CO2 and C-14 according to the standard OCMIP-2 protocols. No biological effects are included. The ocean model carries only DIC and DIC14. We describe five types of abiotic simulations: (1) Equilibrium run, (2) Historical run for 1765-2000, (3) Future runs (IPCC S650 and CIS92A) for DIC only, (4) a 1000-yr Pulse Input run for DIC only, and (5) three Control runs needed for drift correction for the Abiotic transient runs (i.e., the Historical, Future, and Pulse simulations).
