在20世纪90年代，作为世界海洋环流实验（WOCE）、全球海洋通量联合研究（JGOFS）和海洋大气碳交换研究（OACES）的一部分进行了海洋采样考察。随后，一组美国科学家将这些数据合成为易于使用和随时可用的产品。这项合作被称为全球海洋数据分析项目（GLODAP）。结果被合并成一个通用格式的数据集，按海洋分开。为了便于比较，每个海洋数据集都包含少量高质量的历史巡航。数据经过严格的质量控制程序，以消除系统数据测量偏差。校正后的1990年代数据用于估算人为CO2、潜在碱度、CFC水团年龄、CFC分压、核弹产生的放射性碳和天然放射性碳。这些量被合并到测量的数据文件中。这些数据被用于在33个深度表面上以1度分辨率生成客观网格属性图，这些深度表面选择与现有的温度、盐度、氧气和营养成分相匹配。尽管这种假设不准确，但将绘制的油田解释为年平均分布。校准数据和网格化产品均可从二氧化碳信息分析中心获得。在这里，我们描述了数据处理和映射过程的重要细节，并给出了各种参数的汇总量和积分。
During the 1990s, ocean sampling expeditions were carried out as part of the World Ocean Circulation Experiment (WOCE), the Joint Global Ocean Flux Study (JGOFS), and the Ocean Atmosphere Carbon Exchange Study (OACES). Subsequently, a group of U.S. scientists synthesized the data into easily usable and readily available products. This collaboration is known as the Global Ocean Data Analysis Project (GLODAP). Results were merged into a common format data set, segregated by ocean. For comparison purposes, each ocean data set includes a small number of high-quality historical cruises. The data were subjected to rigorous quality control procedures to eliminate systematic data measurement biases. The calibrated 1990s data were used to estimate anthropogenic CO2, potential alkalinity, CFC watermass ages, CFC partial pressure, bomb-produced radiocarbon, and natural radiocarbon. These quantities were merged into the measured data files. The data were used to produce objectively gridded property maps at a 1degrees resolution on 33 depth surfaces chosen to match existing climatologies for temperature, salinity, oxygen, and nutrients. The mapped fields are interpreted as an annual mean distribution in spite of the inaccuracy in that assumption. Both the calibrated data and the gridded products are available from the Carbon Dioxide Information Analysis Center. Here we describe the important details of the data treatment and the mapping procedure, and present summary quantities and integrals for the various parameters.
