However, they are rarely found to exceed 200 years in age. Thus, it is imperative to continuously develop alternative taxa for paleoreconstructions. Colpophyllia natans, a highly populous tropical North Atlantic coral, are known to grow large colonies, potentially containing environmental records spanning several hundreds of years. However, its low density and complicated architecture poses a challenge in extracting climate signals from this coral. This study presents the first monthly-resolved climate calibration of Colpophyllia natans and validates its utility as a new paleoarchive, relative to Siderastrea siderea. Linear regressions of monthly and interannual coral Sr/Ca with instrumental SST reveal robust, significant relationships (p<0.05), indicating that microsampling along a single thecal wall of C. natans allowed for robust climate reconstructions. Additionally, both corals capture similar SST variations (t-test, p≥0.05), which allowed for the generation of a single, composite interspecies SST record that correlates with instrumental SST even more strongly (p<0.0001) than the individual corals. Mean annual and boreal summer interspecies SST correlate significantly with North Atlantic SST indices (p<0.05), demonstrating the ability to capture regional, long-term SST trends in the North Atlantic. Spatial correlation maps of boreal winter interspecies SST to instrumental SST and geopotential height anomalies reveal coherent spatial patterns linked to the North Atlantic Oscillation. Our findings suggest that Colpophyllia natans has enormous potential as a new paleoclimate archive for reconstructing temporal and spatial SST variability in the tropical Atlantic. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: 1903586 #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Niarchos Foundation # Grant: #--------------------------------------- # Site_Information # Site_Name: St. Giles Island and Little Tobago-Speyside # Location: Trinidad and Tobago # Northernmost_Latitude: 11.354 # Southernmost_Latitude: 11.301 # Easternmost_Longitude: -60.508 # Westernmost_Longitude: -60.529 # Elevation_m: #--------------------------------------- # Data_Collection # Collection_Name: SG1 and SPEY1 interannual Sr/Ca Ong2022 # First_Year: 1988 # Last_Year: 2015 # Time_Unit: year Common Era # Core_Length_m: # Parameter_Keywords: trace metals # 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) # ## Year_AD age,,,year Common Era,,,,,N, ## SG1_SrCa_Annual strontium/calcium,coral,,millimole per mole,annual,corals and sclerosponges,,inductively-coupled plasma atomic emission spectroscopy,N,Colpophyllia natans ## SG1_SrCa_DJFM strontium/calcium,coral,,millimole per mole,Dec-Mar,corals and sclerosponges,,inductively-coupled plasma atomic emission spectroscopy,N,Colpophyllia natans ## SG1_SrCa_JJAS strontium/calcium,coral,,millimole per mole,Jun-Sep,corals and sclerosponges,,inductively-coupled plasma atomic emission spectroscopy,N,Colpophyllia natans ## SPEY1_SrCa_Annual strontium/calcium,Siderastrea siderea,,millimole per mole,annual,corals and sclerosponges,,inductively-coupled plasma atomic emission spectroscopy,N, ## SPEY1_SrCa_DJFM strontium/calcium,Siderastrea siderea,,millimole per mole,Dec-Mar,corals and sclerosponges,,inductively-coupled plasma atomic emission spectroscopy,N, ## SPEY1_SrCa_JJAS strontium/calcium,Siderastrea siderea,,millimole per mole,Jun-Sep,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: NaN Year_AD SG1_SrCa_Annual SG1_SrCa_DJFM SG1_SrCa_JJAS SPEY1_SrCa_Annual SPEY1_SrCa_DJFM SPEY1_SrCa_JJAS 2015.000 9.1917 9.22225 9.1658 8.7782 8.800615 8.7500 2014.000 9.1719 9.2115775 9.1567 8.7919 8.863025 8.7610 2013.000 9.1672 9.2242825 9.1298 8.7686 8.8067725 8.7267 2012.000 9.1402 9.1799575 9.1066 8.7552 8.8167475 8.7040 2011.000 9.1168 9.1502 9.0796 8.7383 8.7834725 8.7044 2010.000 9.1404 9.20088 9.0990 8.7444 8.8227725 8.6995 2009.000 9.1346 9.1809325 9.0969 8.7844 8.806665 8.7576 2008.000 9.1581 9.20204 9.1231 8.7765 8.815955 8.7393 2007.000 9.1515 9.1936 9.1118 8.7468 8.82258 8.7100 2006.000 9.1448 9.17614 9.1279 8.7607 8.8139025 8.7149 2005.000 9.1275 9.1524975 9.0929 8.7398 8.79831 8.6785 2004.000 9.1618 9.20509 9.1631 8.7690 8.8222175 8.7382 2003.000 9.1572 9.206035 9.1138 8.8136 8.887575 8.7620 2002.000 9.1855 9.210575 9.1543 8.8157 8.8616875 8.7771 2001.000 9.1771 9.2475325 9.1369 8.8106 8.8852925 8.7630 2000.000 9.1817 9.20365 9.1352 8.7902 8.847405 8.7343 1999.000 9.1449 9.2046825 9.0921 8.7521 8.8142675 8.7041 1998.000 9.1410 9.199325 9.0956 8.7493 8.8029825 8.6954 1997.000 9.1576 9.197275 9.1331 8.7838 8.8717275 8.7483 1996.000 9.1706 9.2184575 9.1410 8.8122 8.8449725 8.7694 1995.000 9.1363 9.164185 9.0915 8.7783 8.87656 8.7075 1994.000 9.1659 9.18662 9.1544 8.8201 8.8603475 8.7914 1993.000 9.1486 9.2051 9.0943 8.8340 8.86343 8.8047 1992.000 9.1473 9.19348 9.1169 8.8051 8.8383025 8.7945 1991.000 9.1497 9.194815 9.1151 8.7987 8.844385 8.7798 1990.000 9.1688 9.210915 9.1270 8.7984 8.847615 8.7653 1989.000 9.1527 9.192015 9.1184 8.8044 8.8816625 8.7486 1988.000 9.1437 NaN 9.1018 8.7894 NaN 8.7339
