3D X-ray computed tomography gray value and age model datasets of Calaguas and Palaui coral cores (Philippines)

The datasets in this article contain raw data of the coral age model, gray values, and SST matching of the Calaguas and Palaui coral cores. There is a total of nine (9) datasets: 1. CS1O – segment 1 (top) of Calaguas coral core matched with OISST 2. CS2O – segment 2 of Calaguas coral core matched with OISST 3. CS3aO – segment 3a of Calaguas coral core matched with OISST 4. CS3bE – segment 3b of Calaguas coral core matched with ERSST 5. CS4E – segment 4 of Calaguas coral core matched with ERSST 6. CS5E – segment 5 of Calaguas coral core matched with ERSST 7. PS1O – segment 1 (top) of Palaui coral core matched with OISST 8. PS2O – segment 2 of Palaui coral core matched with OISST 9. PS3O – segment 3 of Palaui coral core matched with OISST Each dataset contains four (4) .csv files: a. data – has 2 columns, pixel no. and gray value. This is the output of the 3DXCT analysis. Gray values were taken from top to bottom of each segment, as shown in Fig. 1. b. target – has 2 columns, date (in number format = number of days from January 1, 1900) and SST in degC, based on OISST [1,2] or ERSST [3]. These are the daily record of SST of the study site. c. time model – has 2 columns, pixel no. and date (in number format). All tie points between gray values and SST are recorded in this file. d. data with ages – has 3 columns, pixel no., gray value, and date (in number format). This is the output of gray value vs. SST matching, i.e., the resulting age model of each coral core segments. The data, target, and time model files can be directly used as input files in the QAnalySeries software [4] to view or edit the gray value vs. SST matching.本文所涉数据集包含卡拉瓜斯（Calaguas）与帕劳伊（Palaui）珊瑚岩芯的珊瑚年代模型、灰度值及海表温度（Sea Surface Temperature, SST）匹配原始数据。 本次共包含9个数据集，具体如下： 1. CS1O：卡拉瓜斯珊瑚岩芯第1段（上段）与最优插值海表温度（Optimum Interpolation Sea Surface Temperature, OISST）匹配数据集 2. CS2O：卡拉瓜斯珊瑚岩芯第2段与OISST匹配数据集 3. CS3aO：卡拉瓜斯珊瑚岩芯3a段与OISST匹配数据集 4. CS3bE：卡拉瓜斯珊瑚岩芯3b段与扩展重建海表温度（Extended Reconstructed Sea Surface Temperature, ERSST）匹配数据集 5. CS4E：卡拉瓜斯珊瑚岩芯第4段与ERSST匹配数据集 6. CS5E：卡拉瓜斯珊瑚岩芯第5段与ERSST匹配数据集 7. PS1O：帕劳伊珊瑚岩芯第1段（上段）与OISST匹配数据集 8. PS2O：帕劳伊珊瑚岩芯第2段与OISST匹配数据集 9. PS3O：帕劳伊珊瑚岩芯第3段与OISST匹配数据集 每个数据集均包含4个.csv格式文件，详情如下： a. data.csv：包含像素编号与灰度值两列，为三维X射线计算机断层扫描（Three-Dimensional X-ray Computed Tomography, 3DXCT）分析的输出结果。灰度值按各岩芯段自上而下的顺序采集，对应图1所示内容。 b. target.csv：包含日期（数字格式，即自1900年1月1日起的累计天数）与海表温度（单位：℃）两列，数据基于OISST[1,2]或ERSST[3]，为研究区域的逐日海表温度记录。 c. time model.csv：包含像素编号与日期（数字格式）两列，记录了灰度值与海表温度间的全部匹配控制点。 d. data with ages.csv：包含像素编号、灰度值与日期（数字格式）三列，为灰度值与海表温度匹配的输出结果，即各珊瑚岩芯段对应的年代模型。 上述data、target及time model文件可直接作为QAnalySeries软件[4]的输入文件，用于查看或编辑灰度值与海表温度的匹配结果。
