We describe spatial and temporal variations in the partial pressure of carbon dioxide (pCO 2 ) in the central and western equatorial Pacific on the basis of measurements conducted for the periods between 1987 and 1994. Surface water pCO 2 data indicate the significant differences in longitudinal distribution depending on the ocean conditions. We examine the relationship between the area showing higher surface pCO 2 values and the El Niño/Southern Oscillation phenomenon by using the Southern Oscillation Index. Results indicate that the area showing higher surface pCO 2 values correlates with the SOI, which suggests significant intra‐ and interannual fluctuations of CO 2 outflux from the central and western equatorial Pacific.
