The datasets here contain the 3D X-ray computed tomography (3DXCT) gray values and age models of coral cores Baler 2 and 3, taken from Baler, Aurora, Philippines. 3DXCT was used to analyze 5 mm-thick slabs of the coral cores. From the resulting 3DXCT images, gray values were determined per pixel from top to bottom of the slabs. The gray value profiles across the length of the slabs were then matched with records of sea surface temperature (SST) of the Baler site to construct the age model of the coral cores. Daily SST records from October 2018 to February 1982 were from the Optimum Interpolation Sea Surface Temperature or OISST [1,2], while monthly SST records from February 1982 to May 1945 were from the Extended Reconstructed Sea Surface Temperature or ERSST [3]. The gray value datasets of coral cores Baler 2 and 3 present historical records of the corals' response to changing environments through the years and may be used in studies related to such. An example of this can be seen in the relationship between coral gray values and SST. Furthermore, the age model datasets of Baler 2 and 3 serve as the basis for interpretation for all current and future studies on these coral cores. These datasets were originally produced for the research work titled "A historical record of the impact of nuclear activities based on I in coral cores in Baler, Philippines: an update" [4].
这里的数据集包含取自菲律宾奥罗拉省巴勒的珊瑚岩芯Baler 2和3的三维X射线计算机断层扫描（3DXCT）灰度值和年龄模型。3DXCT用于分析珊瑚岩芯5毫米厚的切片。从所得的3DXCT图像中，确定切片从上到下每个像素的灰度值。然后将切片长度上的灰度值剖面与巴勒站点的海面温度（SST）记录进行匹配，以构建珊瑚岩芯的年龄模型。2018年10月至1982年2月的每日SST记录来自最佳插值海面温度（OISST）[1,2]，而1982年2月至1945年5月的每月SST记录来自扩展重建海面温度（ERSST）[3]。珊瑚岩芯Baler 2和3的灰度值数据集呈现了这些珊瑚多年来对不断变化的环境的响应的历史记录，可用于相关研究。珊瑚灰度值与SST之间的关系就是一个例子。此外，Baler 2和3的年龄模型数据集是所有当前和未来关于这些珊瑚岩芯研究的解释基础。这些数据集最初是为名为“基于菲律宾巴勒珊瑚岩芯中碘的核活动影响的历史记录：更新”的研究工作而生成的[4]。
