英文摘要: Sustained time series have provided compelling evidence for progressive acidification of the surface oceans through exchange with the growing atmospheric reservoir of carbon dioxide. However, few long-term programs exist, and extrapolation of results from one site to larger oceanic expanses is hampered by the lack of spatial coverage inherent to Eulerian sampling. Since 1988, the Hawaii Ocean Time-series program has sampled CO2 system variables nearly monthly at Station ALOHA, a deep ocean site windward and 115 km north of the island of Oahu. Surface measurements have also been made at Station Kahe, a leeward site 12 km from the island and on the opposite side of the Hawaiian Ridge. Despite having different physical settings, the sites exhibit identical rates of surface pCO2 increase and hydrogen ion accumulation, suggesting that atmospheric forcing dominates over local dynamics in determining the CO2 trend in the surface waters of the North Pacific subtropical gyre. Key Points Annual cycles and secular trends explain much surface CO2 temporal variabilityPhysically contrasting time-series sites yield common biogeochemical trendsOcean acidification rates on either side of the Hawaiian Ridge are identical ©2014.
