Geophysical Research Letters, 45(8), pp.3542-3549. # Abstract: Reconstructions of ocean temperatures prior to the industrial era serve to constrain natural climate variability on decadal to centennial timescales, yet relatively few such observations are available from the west Pacific Warm Pool. Here we present multiple coral-based sea surface temperature reconstructions from Yongle Atoll, in the South China Sea over the last ~1,250 years (762-2013 Common Era [CE]). Reconstructed coral Sr/Ca-sea surface temperatures indicate that the "Little Ice Age (1711-1817 CE)" period was ~0.7°C cooler than the "Medieval Climate Anomaly (913-1132 CE)" and that late 20th century warming of the western Pacific is likely unprecedented over the past millennium. Our findings suggest that the Western Pacific Warm Pool may have expanded (contracted) during the Medieval Climate Anomaly (Little Ice Age), leading to a strengthening (weakening) of the Asian summer monsoon, as recorded in Chinese stalagmites. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Natural Science Foundation of China  # Grant: 41476038, 41676049 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Chinese Academy of Sciences (CAS) Youth Innovation Promotion Association # Grant: 2015284 #--------------------------------------- # Site_Information # Site_Name: Lingyang Reef, Yongle Atoll # Location: South China Sea # Northernmost_Latitude: 16.45 # Southernmost_Latitude: 16.45 # Easternmost_Longitude: 111.61 # Westernmost_Longitude: 111.61 # Elevation_m: #--------------------------------------- # Data_Collection # Collection_Name: LY2_Cheng2018 # First_Year: 1987 # Last_Year: 2013 # Time_Unit: year Common Era # Core_Length_m: # Parameter_Keywords: trace metals # Notes: #--------------------------------------- # Chronology_Information # Chronology: #--------------------------------------- # Variables # PaST_Thesaurus_Download_Resource: https://www.ncdc.noaa.gov/paleo/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) # ## Year age,,,year Common Era,,corals and sclerosponges,,,N, ## Sr/Ca strontium/calcium,Porites sp.,,millimole per mole,,corals and sclerosponges,,inductively-coupled plasma atomic emission spectroscopy,N, #------------------------ # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: Year Sr/Ca 2013.42 8.346 2013.25 8.413 2013.085 8.565 2012.92 8.514 2012.75 8.446 2012.585 8.401 2012.42 8.367 2012.25 8.41 2012.085 8.645 2011.92 8.624 2011.75 8.52 2011.585 8.436 2011.42 8.421 2011.25 8.54 2011.085 8.638 2010.92 8.556 2010.75 8.434 2010.585 8.37 2010.42 8.401 2010.25 8.48 2010.085 8.58 2009.92 8.536 2009.75 8.463 2009.585 8.377 2009.42 8.397 2009.25 8.462 2009.085 8.582 2008.92 8.528 2008.75 8.4 2008.585 8.417 2008.42 8.443 2008.25 8.565 2008.085 8.653 2007.92 8.601 2007.75 8.465 2007.585 8.387 2007.42 8.388 2007.25 8.519 2007.085 8.62 2006.92 8.577 2006.75 8.509 2006.585 8.426 2006.42 8.391 2006.25 8.476 2006.085 8.61 2005.92 8.58 2005.75 8.555 2005.585 8.42 2005.42 8.42 2005.25 8.542 2005.085 8.654 2004.92 8.62 2004.75 8.445 2004.585 8.409 2004.42 8.436 2004.25 8.533 2004.085 8.629 2003.92 8.564 2003.75 8.483 2003.585 8.398 2003.42 8.455 2003.25 8.595 2003.085 8.667 2002.92 8.596 2002.75 8.463 2002.585 8.41 2002.42 8.415 2002.25 8.491 2002.085 8.619 2001.92 8.578 2001.75 8.435 2001.585 8.429 2001.42 8.409 2001.25 8.548 2001.085 8.684 2000.92 8.586 2000.75 8.523 2000.585 8.425 2000.42 8.496 2000.25 8.584 2000.085 8.645 1999.92 8.527 1999.75 8.455 1999.585 8.47 1999.42 8.443 1999.25 8.554 1999.085 8.641 1998.92 8.583 1998.75 8.423 1998.585 8.4 1998.42 8.38 1998.25 8.525 1998.085 8.655 1997.92 8.631 1997.75 8.53 1997.585 8.421 1997.42 8.403 1997.25 8.618 1997.085 8.715 1996.92 8.624 1996.75 8.455 1996.585 8.4 1996.42 8.456 1996.25 8.609 1996.085 8.688 1995.92 8.574 1995.75 8.476 1995.585 8.427 1995.42 8.45 1995.25 8.579 1995.085 8.702 1994.92 8.656 1994.75 8.589 1994.585 8.486 1994.42 8.438 1994.25 8.596 1994.085 8.692 1993.92 8.625 1993.75 8.55 1993.585 8.491 1993.42 8.413 1993.25 8.515 1993.085 8.71 1992.92 8.67 1992.75 8.586 1992.585 8.42 1992.42 8.46 1992.25 8.575 1992.085 8.685 1991.92 8.562 1991.75 8.475 1991.585 8.475 1991.42 8.447 1991.25 8.577 1991.085 8.646 1990.92 8.558 1990.75 8.476 1990.585 8.429 1990.42 8.471 1990.25 8.589 1990.085 8.662 1989.92 8.655 1989.75 8.475 1989.585 8.452 1989.42 8.511 1989.25 8.605 1989.085 8.65 1988.92 8.584 1988.75 8.417 1988.585 8.38 1988.42 8.37 1988.25 8.609 1988.085 8.683 1987.92 8.58
