More than 250 carbon-14 accelerator mass spectrometry dates of terrestrial macrofossils from annually laminated sediments from Lake Suigetsu (Japan) provide a first atmospheric calibration for almost the total range of the radiocarbon method (45,000 years before the present). The results confirm the (recently revised) floating German pine chronology and are consistent with data from European and marine varved sediments, and combined uranium-thorium and carbon-14 dating of corals up to the Last Glacial Maximum. The data during the Glacial show large fluctuations in the atmospheric carbon-14 content, related to changes in global environment and in cosmogenic isotope production.
来自日本水俣湖年纹层沉积物中陆生大型化石的250多个碳-14加速器质谱测年数据，为放射性碳方法几乎整个量程（距今45,000年）提供了首个大气校正。结果证实了（最近修订的）浮动德国松树年表，并且与来自欧洲和海洋纹层沉积物的数据，以及直至末次盛冰期的珊瑚的铀钍和碳-14联合测年数据一致。冰期期间的数据显示，大气碳-14含量有大幅波动，这与全球环境变化和宇宙成因同位素产生有关。
