%X A three-dimensional ocean carbon cycle model, which is a general circulation model coupled with simple biogeochemical processes, is developed. The OGCM used is a modified version of the Geophysical Fluid Dynamics Laboratory modular ocean model (MOM2). The ocean chemistry and a simple ocean biota model is included. Principal variables are total CO 2 , alkalinity and phosphate. The vertical profile of POC flux observed by sediment traps is adopted, the rain ratio, a ratio of production rate of calcite against that of POC, and the bio-production efficiency should be 0.06 and 2 per year, separately. Model distributions of chemical species compared with distributions observed during the GEOSECS are well reproduced.
