The samples were collected at a water depth below 1000 m where the seawater temperature is around 3 ℃. The analyses of Mg isotope were performed on multi-collector inductively coupled plasma mass spectrometry and the elemental composition was tested on laser ablation inductively coupled plasma mass spectrometry. The dataset is aimed at tracing the Mg isotope fractionation pattern and Mg elemental incorporation into the cold-water bamboo coral skeleton. 110.71 117.12 16.55 17.64 113.74933333333335 17.064 2018-05-13T12:05:00 2020-08-25T15:42:00 3 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Sample code/label | Sample label | Measurement point's distance relative to the growth central axis | Distance | Dist | Structure | δ26Mg | Multiple collector inductively-coupled plasma mass spectrometer | 2sd | δ26Mg, standard deviation | δ26Mg std dev | δ25Mg | δ25Mg, standard deviation | δ25Mg std dev | Magnesium/Calcium ratio | Mg/Ca | Laser Ablation Inductively Coupled Mass Spectrometer | Boron/Calcium ratio | B/Ca | Strontium/Calcium ratio | Sr/Ca | Barium/Calcium ratio | Ba/Ca | Comment | Axis | Diffraction angle | Diff angle | X-ray diffraction (XRD) | Intensity | Mid-I | Edge citable cold-water octocoral Mg/Ca Mg isotopes method12 method17989 method17990 param106327 param114908 param114909 param128045 param128046 param1570 param171658 param180103 param2265 param2800 param790 param91392 param91393 param96232 pi111466 author111466 author114046 author114047 author59396 author66184 author66871 author67010 author91120 author91130 author91350 geocode1599 geocode1600 geocode1601 inst1769 inst22380 license21 term47481 term51403 term71696
