本文的重点是转换放射性碳年龄的间隔24000 -0 cal BP（在目前之前，0 cal BP = AD 1950），基于一个样本集的树木年轮，铀钍定年珊瑚，和纹计数海洋沉积物的校准（cal）年龄。由许多实验室产生的（14）C年龄-校准年龄信息被转换成大气和海洋的Delta（14）C剖面和校准曲线。我们讨论了测量的（14）C年龄的偏移及其误差，区域（14）C年龄差异，树珊瑚（14）C年龄比较和海洋水库年龄的时间依赖性，并评估十年与一年（14）C结果。海洋深水环流的变化，特别是16，000 - 11，000 cal sp间隔的变化，反映在INTCAL 98的Delta（14）C值中。
The focus of this paper is the conversion of radiocarbon ages to calibrated (cal) ages for the interval 24,000-0 cal BP (Before Present, 0 cal BP = AD 1950), based upon a sample set of dendrochronologically dated tree rings, uranium-thorium dated corals, and varve-counted marine sediment. The (14)C age-cal age information, produced by many laboratories, is converted to Delta(14)C profiles and calibration curves, for the atmosphere as well as the oceans. We discuss offsets in measured (14)C ages and the errors therein, regional (14)C age differences, tree-coral (14)C age comparisons and the time dependence of marine reservoir ages, and evaluate decadal vs. single-year (14)C results. Changes in oceanic deepwater circulation, especially for the 16,000-11,000 cal sp interval, are reflected in the Delta(14)C values of INTCAL98.
