我们评估了海洋水库年龄R（t）的西北太平洋沿岸地区使用放射性碳测量的年度带状珊瑚芯（滨珊瑚SP）收集在日本南部的石垣岛。20世纪初石垣岛太平洋沿岸的储层年龄R（t）介于290 ~ 455 14 C yr之间，加权平均值为355 ± 25 14 C yr（n=5，±1 σ）。1900 ~ 1950年，全球海洋表层14 C年龄的平均差值ΔR为35 ± 25 14 C年（n=5，±1σ）。
We assessed marine reservoir age R(t) for the costal area of the northwest Pacific using radiocarbon measurements of the annually banded coral core (Porites sp) collected on Ishigaki Island in southern Japan. Reservoir age R(t) during the early 1900s at the Pacific coast of Ishigaki Island ranged between 290 and 455 14C yr, with a weighted mean of 355 ± 25 14C yr (n=5, ±1 σ). The regional-specific ΔR, defined as 14C age difference of regional and world ocean surface layer, was 35 ± 25 14C yr (n=5, ±1σ) on average and increased between 1900 and 1950.
