Here, we reconstructed the inter-annual variability in central equatorial Pacific surface water d14C from 1922-1956 using near-monthly radiocarbon measurements in a Porites sp. coral skeleton (FI5A) from the windward side of Fanning Island (3 deg 54'32""N, 159 deg 18'88""W). The most pronounced feature in this record is a large positive shift in d14C between 1947 and 1956 that coincides with the switch of the Pacific Decadal Oscillation (PDO) from a positive to a negative phase in the mid-1940s. Although the absolute d14C values from 1950 - 1955 in FI5A differ from the d14C values of another coral core collected from the opposite side of the island, both records show a large positive shift in their d14C records at that time. The relative increase in d14C of each record is consistent with the premise that a common mechanism is controlling the d14C records within each coral record. Overall, the Fanning d14C data support the notion that a significant amount of subtropical seawater is arriving at the equator but does not allow us to determine the mechanism for its transport. #-------------------- # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: OCE9896157 #-------------------- # Funding_Agency # Funding_Agency_Name: US National Oceanic and Atmospheric Administration (NOAA) # Grant: NA96GP0395 #-------------------- # Funding_Agency # Funding_Agency_Name: Andrew W.
