Part of the global seawater delta oxygen-18 database from reference Craig 1965

Correction of SMOW data to GEOSECS standard by addition of 0.07. Positions and salinities partly read off a graph. Temperatures partly interpolated from nearby stations.本数据集通过向标准平均海水（Standard Mean Ocean Water, SMOW）数据添加0.07，将其校正至全球海洋断面调查（Global Ocean Section Study, GEOSECS）标准；站位信息与盐度数据部分系从图表中读取所得，温度数据则部分通过邻近站位插值得到。
