However, limited direct observations hinder our understanding of KI’s mechanisms and responses to climate change. Here, we present a 60-year bi-monthly resolved coral oxygen isotope (d18Oc) record from Dongsha Atoll, the northern SCS. The dry-season (December-March) d18Oc record reveals interannual to decadal variabilities of the KI. The impact of the East Asian winter monsoon (EAWM) on Dongsha d18Oc was more pronounced during the 1970s and 1980s and after the early 2000s, while the influence of the El Niño-Southern Oscillation (ENSO) on Dongsha d18Oc was higher between the 1980s and 1990s. The Pacific Decadal Oscillation (PDO) may have a relatively minor effect on KI strength or may indirectly modulate KI strength through its influence on ENSO activities. Our Dongsha d18Oc record highlight the importance of the EAWM, ENSO, and PDO in predicting future KI changes. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #--------------------------------------- # Site_Information # Site_Name: Dongsha Atoll Coral # Location: South China Sea # Northernmost_Latitude: 20.62 # Southernmost_Latitude: 20.62 # Easternmost_Longitude: 116.7 # Westernmost_Longitude: 116.7 # Elevation_m: #--------------------------------------- # Data_Collection # Collection_Name: wet_d18O_SrCa # First_Year: 1952 # Last_Year: 2015 # Time_Unit: year Common Era # Core_Length_m: # Parameter_Keywords: trace metals, oxygen isotopes # Notes: #--------------------------------------- # Chronology_Information # Chronology: #--------------------------------------- # Variables # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## Date age,,,Year Common Era,Jun-Sep,corals and sclerosponges,,,N, ## Sr/Ca strontium/calcium,Porites sp.,,millimole per mole,Jun-Sep,corals and sclerosponges,,,N, ## d18O delta 18O,Porites sp.,,per mil,Jun-Sep,corals and sclerosponges,,,N, #------------------------ # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: Date Sr/Ca d18O 2015 8.809 -5.058 2014 8.832 -4.775 2013 8.824 -5.163 2012 8.844 -5.280 2011 8.832 -5.110 2010 8.903 -4.664 2009 8.858 -4.926 2008 8.863 -4.977 2007 8.858 -4.763 2006 8.823 -5.177 2005 8.864 -4.555 2004 8.882 -4.649 2003 8.838 -4.556 2002 8.822 -4.279 2001 8.834 -4.756 2000 8.859 -5.091 1999 8.826 -4.931 1998 8.804 -4.715 1997 8.844 -4.871 1996 8.839 -5.071 1995 8.860 -4.868 1994 8.856 -5.059 1993 8.821 -4.979 1992 8.790 -4.698 1991 8.843 -4.857 1990 8.871 -4.674 1989 8.839 -4.835 1988 8.853 -4.943 1987 8.853 -5.080 1986 8.850 -5.387 1985 8.942 -4.549 1984 8.839 -5.280 1983 8.807 -4.965 1982 8.824 -4.851 1981 8.831 -5.438 1980 8.865 -4.732 1979 8.918 -4.982 1978 8.860 -5.014 1977 8.935 -4.925 1976 8.832 -4.879 1975 8.837 -5.201 1974 8.895 -5.070 1973 8.877 -5.014 1972 8.837 -4.955 1971 8.844 -4.706 1970 8.825 -4.447 1969 8.829 -4.623 1968 8.880 -4.309 1967 8.866 -4.509 1966 8.856 -4.429 1965 8.855 -4.673 1964 8.844 -4.598 1963 8.853 -4.759 1962 8.892 -4.659 1961 8.862 -4.758 1960 8.886 -4.887 1959 8.854 -5.072 1958 8.828 -5.158 1957 8.865 -4.904 1956 8.900 -4.823 1955 8.855 -4.784 1954 8.790 -4.950 1953 8.858 -4.950 1952 8.836 -4.842
