Tropical sea surface temperatures for the past four centuries reconstructed from coral archives

d18Osw (residuals calculated from coupled SrCa and d18O measurements)

interannual d18OSW variations can largely be explained by months-long changes in precipitation minus evaporation and zonal advection

On interannual timescales, Palmyra d18Osw is significantly correlated with ENSO variability (R=-049 for Eastern Pacific Warming, R=-0.19 for Central Pacific Warming), reflecting ENSO related changes in local precipitation and ocean advection. On decadal time-scales, d18Osw likely reflects salinity changes due to larger processes such as PDO.

d18Osw derived using Ren et al., 2002 method, with Sr/CaSST slope of 0.09 mmol/mol/permilC and d18OSST slope of 0.21 permil/permilC
