In the western Pacific region, relatively few reconstructions exist north of the Western Pacific Warm Pool (WPWP), a region critical to global climate. In this study, we collected a coral core from Houbihu, southern Taiwan and generated a 225-year reconstruction of annual and wintertime sea surface temperature (SST), dry season sea surface salinity (SSS) and wet season rainfall records derived from paired Porites Sr/Ca and d18O profiles extending back to the end of the Little Ice Age (LIA, 1850 CE). Multidecadal SST trends generally track regional surface temperature reconstructions, indicating the dominant influence of solar and volcanic radiative forcings. Reconstructed dry season SSS reflects an advection signal linked to the East Asian Winter Monsoon (EAWM) and the Pacific Decadal Oscillation (PDO), both influencing variations in the Kuroshio Intrusion (KI) across the Luzon Strait. Reconstructed wet season rainfall, on the other hand, reveals influence of the PDO on the decadal variability of local and regional rainfall patterns. Relative to the late 1900s, our climate reconstructions document cooler and drier (high salinity and low rainfall) conditions during the end of the LIA, supporting other lines of evidence of a retracted WPWP region during this period. In the late 20th to early 21st century, our climate reconstructions record warming and freshening (low salinity and high rainfall) trends, highlighting the potential impact of anthropogenic forcing in the extension of the WPWP. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Research Foundation Singapore # Grant: NRF-RF2012-03 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Ministry of Education, Singapore Academic Research Fund Tier 2 # Grant: Project MOE2016-T2-1-016 #--------------------------------------- # Site_Information # Site_Name: Houbihu, southern Taiwan # Location: Taiwan # Country: Taiwan # Northernmost_Latitude: 21.9 # Southernmost_Latitude: 21.9 # Easternmost_Longitude: 120.7 # Westernmost_Longitude: 120.7 # Elevation: -6 #--------------------------------------- # Data_Collection # Collection_Name: HBH wet-dry season Ramos2020 # First_Year: 1788 # Last_Year: 1905 # Time_Unit: AD # Core_Length: # Notes: #--------------------------------------- # Chronology_Information # Chronology: #--------------------------------------- # Variables # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) ## age_AD age,,,year Common Era,,corals and sclerosponges,,,N, ## d18O-Porites-dry delta 18O,Porites sp.,,per mil,Dec-Mar,corals and sclerosponges,,isotope ratio mass spectrometry,N, ## d18O-Porites-wet delta 18O,Porites sp.,,per mil,Jun-Sep,corals and sclerosponges,,isotope ratio mass spectrometry,N, #------------------------ # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: NaN age_AD d18O-Porites-dry d18O-Porites-wet 1788 -5.40874 -4.43476 1789 -5.34151 -4.39902 1790 -5.41915 -4.55657 1791 -5.2968 -4.29516 1792 -5.29867 -4.33342 1793 -5.56406 -4.3663 1794 -5.39107 -4.33141 1795 -5.34491 -4.34466 1796 -5.21714 -4.00658 1797 -5.34354 -4.53979 1798 -5.43128 -4.41463 1799 -5.20405 -4.59583 1800 -5.15056 -4.0205 1801 -5.19014 -4.07637 1802 -5.23047 -4.53996 1803 -5.38713 -4.46093 1804 -5.2311 -3.93644 1805 -5.46588 -4.06178 1806 -5.38729 -4.27218 1807 -5.2747 -4.17096 1808 -5.32186 -4.38248 1809 -5.23366 -4.18385 1810 -5.59431 -4.34525 1811 -5.38522 -4.56782 1812 -5.51665 -3.91461 1813 -5.19613 -4.40004 1814 -5.26379 -4.695 1815 -5.18727 -4.28024 1816 -5.11749 -3.8987 1817 -5.25502 -4.10508 1818 -5.45615 -4.40776 1819 -5.28123 -4.49668 1820 -5.09191 -4.17001 1821 -5.1954 -4.61514 1822 -5.18462 -4.25059 1823 -5.09776 -4.23695 1824 -5.44485 -4.30742 1825 -5.27875 -4.54601 1826 -5.40777 -4.56715 1827 -5.25648 -4.66052 1828 -4.91488 -4.62579 1829 -5.45619 -4.42168 1830 -5.41164 -4.35373 1831 -5.3045 -3.80659 1832 -5.37055 -4.57382 1833 -5.51814 -4.38611 1834 -5.2623 -3.94451 1835 -5.35351 -4.04367 1836 -5.26976 -3.77186 1837 -5.27429 -3.97773 1838 -5.24106 -3.74568 1839 -5.17967 -4.13075 1840 -5.32189 -4.41615 1841 -5.24052 -4.46925 1842 -5.15824 -4.59614 1843 -5.33889 -4.76 1844 -5.48811 -4.60373 1845 -5.26102 -4.50776 1846 -5.15547 -4.75675 1847 -5.36038 -4.51279 1848 -5.28234 -4.37537 1849 -5.3129 -4.25847 1850 -5.16728 -4.57005 1851 -5.20825 -4.35172 1852 -5.22052 -4.54153 1853 -5.42656 -4.22185 1854 -5.33394 -4.31222 1855 -5.17572 -4.71424 1856 -5.45098 -4.6022 1857 -5.31719 -4.8019 1858 -5.52191 -4.82807 1859 -5.72663 -4.5905 1860 -5.54106 -4.60975 1861 -5.41864 -4.38687 1862 -5.09277 -3.9629 1863 -4.96313 -4.34635 1864 -5.44794 NaN 1865 -5.31509 -4.448 1866 -5.06869 -4.46982 1867 -5.13472 -4.30632 1868 -5.52015 -4.37788 1869 -5.36044 -4.37132 1870 -5.62486 -4.01733 1871 -5.38778 -4.34109 1872 -5.39517 -4.4391 1873 -5.34184 -4.41945 1874 -5.24159 -4.10913 1875 -5.0491 -4.09871 1876 -5.09416 -4.40609 1877 -4.93707 -4.36141 1878 -5.30866 -4.70575 1879 -5.18147 -4.13439 1880 -5.50274 -4.70575 1881 -5.67904 NaN 1882 -5.53944 -4.34638 1883 -5.25857 -4.34482 1884 -5.0281 -4.29692 1885 -5.3971 -4.56633 1886 -5.37519 NaN 1887 -5.45064 -4.49327 1888 -5.50348 -4.6651 1889 -5.18619 -4.4265 1890 -5.17574 -4.32789 1891 -5.19774 -4.44892 1892 -5.39627 NaN 1893 -5.1069 -4.35772 1894 -5.3511 -4.46858 1895 -5.27262 -4.40282 1896 -5.49816 -4.70763 1897 -5.71927 -4.85799 1898 -5.51448 -4.57918 1899 -5.39044 -4.65099 1900 -5.20536 -4.52058 1901 -5.19127 -4.37317 1902 -5.25055 -4.76159 1903 -5.22142 -4.51326 1904 -5.22142 -4.64293 1905 -5.22142 -4.60228
