These tracers provide unique  information on the regional water mass history, and together these data  allow us to constrain the variability of circulation in the upper Pacific  over the past four centuries. First, we observe decreases in d18O of coral  from Abraham Reef and Heron Island, indicating an increase in sea surface  temperature and/or a decrease in surface salinity since 1850. Second, the  small Suess effect value (D14C decrease from 1880 to 1955, due mostly to  fossil fuel CO2) observed previously at Abraham Reef [Druffel and Griffin,  1993] is confirmed in the measurements reported here from the Heron Island  coral. This value is low compared to those observed in other areas of the  ocean [Druffel, 1997; Druffel and Linick, 1978; Nozaki et al., 1978]  between 1880 and 1955. Third, we report alterations in the correlation  between El Nino events and the occurrence of low D14C, which is indicative  of long-term change(s) in circulation in the SW Pacific. The D14C shifts  reported here are not large, but even small temporal changes in prebomb  D14C suggest that important changes in the large-scale state of the ocean  have occurred, such as a temporal change in circulation.","author":{"name":"Druffel, E.R.M.; Griffin, S"},"citation":"Druffel, E.R.M.; Griffin, S. 1999.
