Core OGA-02-1 was drilled vertically through a living Porites coral at Miyanohama on the north coast of Chichijima in the Ogasawara Islands (Japan), located in the southwestward return flow of the Kuroshio recirculation system. The massive colony, growing at 5.6 m water depth on the island's northern side (27° 6.355’ N, 142° 11.645’ E), is directly exposed to open-ocean conditions. The core is without gap over its total length of 1.74 m. Individual segments fit seamlessly. The bimonthly resolved records of d18O, Sr/Ca, and U/Ca generated from the coral skeleton show clear annual cycles that can be counted back to the year 1873. This age model is corroborated by the skeletal pattern of annual density-band pairs as revealed by X-radiographs. ABSTRACT SUPPLIED BY ORIGINATOR: Instrumental climate observations provide robust records of global land and ocean temperatures during the twentieth century. Unlike for temperature, continuous salinity observations in the surface ocean are scarce prior to 1970, and the magnitude of salinity changes during the twentieth century is largely unknown. Surface ocean salinity is a major component in climate dynamics, as it influences ocean circulation and water mass formation. Here we present an annually resolved reconstruction of salinity variations in the surface waters of the western subtropical North Pacific Ocean since 1873, based on bimonthly records of d18O, Sr/Ca, and U/Ca in a coral from the Ogasawara Islands. The reconstruction indicates that an abrupt regime shift toward fresher surface ocean conditions occurred between 1905 and 1910. Observational atmospheric data suggest that the abrupt freshening was associated with a weakening of the winds that drive the Kuroshio Current system and the associated subtropical gyre circulation. We note that the abrupt early-twentieth-century freshening in the western subtropical North Pacific precedes abrupt climate change in the northern North Atlantic by a few years. The potential for abrupt regime shifts in surface ocean salinity should be considered in climate predictions for the coming decades.
