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: dry_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,,corals and sclerosponges,,,N, ## Sr/Ca strontium/calcium,Porites sp.,,millimole per mole,Dec-Mar,corals and sclerosponges,,,N, ## d18O delta 18O,Porites sp.,,per mil,Dec-Mar,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 9.021 -4.646 2014 9.134 -4.011 2013 9.129 -4.204 2012 9.039 -4.722 2011 9.093 -4.486 2010 9.100 -4.241 2009 9.100 -4.275 2008 9.098 -4.384 2007 9.133 -4.036 2006 9.070 -4.450 2005 9.118 -4.288 2004 9.163 -3.856 2003 9.101 -3.900 2002 9.112 -3.947 2001 9.094 -4.215 2000 9.082 -4.137 1999 9.080 -4.167 1998 9.038 -4.444 1997 9.061 -4.244 1996 9.091 -4.592 1995 9.113 -4.215 1994 9.125 -4.090 1993 9.139 -4.030 1992 9.120 -4.285 1991 9.110 -3.775 1990 9.049 -4.067 1989 9.076 -4.635 1988 9.104 -4.537 1987 9.132 -4.365 1986 9.097 -4.577 1985 9.103 -4.275 1984 9.133 -4.114 1983 9.127 -4.180 1982 9.126 -4.323 1981 9.191 -4.377 1980 9.171 -4.166 1979 9.100 -4.171 1978 9.211 -4.290 1977 9.119 -4.168 1976 9.195 -4.377 1975 9.098 -5.060 1974 9.095 -4.166 1973 9.101 -4.324 1972 9.068 -4.382 1971 9.122 -4.054 1970 9.091 -3.966 1969 9.104 -3.884 1968 9.139 -4.026 1967 9.133 -3.545 1966 9.063 -3.933 1965 9.072 -3.516 1964 9.109 -3.805 1963 9.065 -4.189 1962 9.160 -3.872 1961 9.132 -3.839 1960 9.135 -3.812 1959 9.039 -3.972 1958 9.113 -4.068 1957 9.060 -4.298 1956 9.110 -4.102 1955 9.103 -4.095 1954 9.138 -4.210 1953 9.018 -4.321 1952 9.085 -3.802
