Here we \ndemonstrate that the winter Sr/Ca and U/Ca records of an \nannually-banded reef coral from the Ogasawara Islands in the \nwestern subtropical North Pacific are significantly correlated \nwith the instrumental winter PDO index over the last century. \nThe reconstruction of the PDO is further improved by combining \nthe coral data with an existing eastern mid-latitude North \nPacific growth ring record of geoduck clams.

The NDJF value of a given year (e.g., 1901) includes \nthe ND value of the preceding year (1900). The ring-width \nindex is based on annual growth rings of 6 to 23 geoduck shells, \nand has been reported to document local SST and PDO variability \n(Strom et al., 2004). All three time series were detrended \nand normalized to unit variance over their period of overlap \n(1873-1994). Then, a coral index was calculated as the average \nof the detrended and normalized NDJF Sr/Ca and U/Ca time series. \nConsequently, the coral-geoduck index was derived as the average \nof this coral index and the detrended and normalized geoduck \ngrowth index (Felis et al., 2010).\n\nCore OGA-02-1 was drilled vertically through a living Porites \ncoral at Miyanohama on the north coast of Chichijima in the \nOgasawara Islands (Japan).
