The coral cross-sections exhibit tree ring-like concentric growth bands, prompting the selection of two growth directions for testing in samples SY067-7 and SY268-10 to examine the reproducibility of elemental distribution across different growth axes. The main line corresponds with the magnesium isotope testing path, while position represents the measurement points' distance relative to the growth central axis. 110.71 117.12 16.55 17.64 112.90666666666665 16.92 2018-05-13T12:05:00 2020-08-25T15:42:00 -2583.7 -1119.3 SY067-7 16.57 110.71 -1408.8 2018-05-13T12:05:00 ST03 ST03 2018-05-13T00:00:00 2018-05-13 Tansuo-2 Tansuo-2 Human Occupied Vehicle HOV SY185-9 16.55 110.89 -1119.3 2019-07-31T15:34:00 TS12-02 TS12-02 2019-07-31T00:00:00 2019-07-31 Tansuo-2 Tansuo-2 Human Occupied Vehicle HOV SY268-10 17.64 117.12 -2583.7 2020-08-25T15:42:00 TS2-1-3 TS2-1-3 2020-08-25T00:00:00 2020-08-25 Tansuo-2 Tansuo-2 Human Occupied Vehicle HOV 1213 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Event label Event Event Latitude of event Latitude Latitude Longitude of event Longitude Longitude Date/Time of event Date/Time Date/Time Distance Dist mm distance http://purl.obolibrary.org/obo/PATO_0000040 Length L http://dbpedia.org/resource/Length Zeng Zhiwei zwzeng@tongji.edu.cn Measurement point's distance relative to the growth central axis Dist [mm] Magnesium/Calcium ratio Mg/Ca mmol/mol magnesium calcium Ca https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:22984 ratio Laser Ablation Inductively Coupled Mass Spectrometer LA-ICP-MS Zeng Zhiwei zwzeng@tongji.edu.cn Mg/Ca [mmol/mol] Boron/Calcium ratio B/Ca µmol/mol calcium Ca https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:22984 ratio Laser Ablation Inductively Coupled Mass Spectrometer LA-ICP-MS Zeng Zhiwei zwzeng@tongji.edu.cn B/Ca [µmol/mol] Strontium/Calcium ratio Sr/Ca mmol/mol strontium calcium Ca https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:22984 ratio Laser Ablation Inductively Coupled Mass Spectrometer LA-ICP-MS Zeng Zhiwei zwzeng@tongji.edu.cn Sr/Ca [mmol/mol] Barium/Calcium ratio Ba/Ca µmol/mol barium calcium Ca https://www.ebi.ac.uk/chebi/searchId.do?chebiId=CHEBI:22984 ratio Laser Ablation Inductively Coupled Mass Spectrometer LA-ICP-MS Zeng Zhiwei zwzeng@tongji.edu.cn Ba/Ca [µmol/mol] Comment Comment Zeng Zhiwei zwzeng@tongji.edu.cn Comment CurationLevelC Enhanced curation https://wiki.pangaea.de/wiki/Curation_levels citable cold-water octocoral Mg/Ca Mg isotopes author111466 author114046 author114047 author59396 author66184 author66871 author67010 author91120 author91130 author91350 basis5515 campaign3395055 campaign3395064 campaign3395065 campaign52709 campaign52710 campaign52711 curlevel30 event3268452 event3268455 event3268456 geocode1599 geocode1600 geocode1601 geocode8128 inst1769 inst22380 license21 method17988 method17990 param1570 param171658 param2265 param91392 param91393 param96232 pi111466 term1073628 term2663825 term38520 term40663 term40665 term40966 term43863 term47481 term51403 term71696
