Here we introduce a 178?year, seasonally resolved coral oxygen isotopic record from Clarion Island (18°N, 115°W), a region that is strongly influenced by the decadal-scale fluctuations of the North Pacific Gyre Oscillation (NPGO) and a subtropical region that serves as a critical locus for the communication of climate anomalies with the tropics. This Mexican Pacific coral record is highly correlated to coral records from the central tropical Pacific and tree ring records from western North America. Significant changes in the amplitude of oceanic decadal variability in the early 19thcentury are mirrored in the drought reconstructions in western North America. The spatial manifestation of this relationship was relatively invariant, despite notable changes in the climatic mean state. STUDY NOTES: Modern eastern tropical north Pacific coral. Measurement precision of d18O: 0.07 per mil PDB. Basis of d18O climate relation: SST and d18O of seawater (~salinity).
