Climatological output from the Ocean Circulation and Climate Advanced Model (OCCAM) has been examined for consistency and plausibility. The model is of Cox-Semtner type, is global with 36 levels and 1/4 degree resolution, is initialized by Levitus climatology, forced by ECMWF winds and relaxed in the surface layer to monthly Levitus values. The mass and heat flux across 10 Pacific (WOCE) sections has been calculated. The Indo-Pacific Throughflow is found to be 13 Sv with an annual amplitude of 3 Sv. At most latitudes the Sverdrup transport correctly predicts the strength of the western boundary currents, although bottom pressure torques are locally important. The flux of cold bottom water has been determined for all sections and comparison with measurements made with two current meter arrays. At 10°S (Samoa Passage) the agreement is startling but at 32°S it is poor. Puzzling variations in the flux with latitude are found. Comparisons with drifters and floats also are planned.
