Here we show scleractinian coral P/Ca proxy records of variations in phosphate concentrations during El Niño Southern Oscillation (ENSO) cycles in the central equatorial Pacific. Covarying P/Ca records in Porites corals from Christmas and Fanning Islands show a regional ~40% decrease during the upwelling relaxation of the 1997-1998 El Niño, consistent with less frequent nutrient measurements from this area. Similar ~35-45% skeletal P/Ca decreases occur during the 1982–1983 and 1986-1987 El Niño events, which predate satellite color and regional nutrient measurements. After each El Niño event, nutrient increases lag temperature recovery by 4-12months, likely reflecting uptake by massive phytoplankton blooms that followed resumption of upwelling. The results support the utility of coral P/Ca to probe the mechanisms linking ENSO, equatorial upwelling, and carbon cycling in the past. STUDY NOTES: This dataset contains skeletal P/Ca data from 3 Line Island coral records through 3 El Nino events (Fanning and Christmas Islands). This dataset includes all P/Ca data published in LaVigne et al., 2013. Details on chronologies and methodology can be found in the original publication.
