为了确定日本北海道周围海相放射性碳库的年代，比较了来自陆地和海洋哺乳动物的动物群遗骸，并将其归类于相同的考古沉积物。从柔门期(4900BP)到阿伊努期(800BP)的5个不同年龄的贝类中，选择107个动物骨骼样本进行放射性碳测量。日本鹿和北方毛海豹的明显年龄差异表明，该地区深水上升流的影响明显。我们的数据显示了相对稳定的年龄差异，从4500BP到800BP，估计ΔR值在38014C年左右。结果与以往基于模拟模型和海洋性质的估算结果一致。
Faunal remains originating from terrestrial and marine mammals, and belonging to the same archaeological deposits were compared to evaluate the marine radiocarbon reservoir ages around the Hokkaido island, Japan. From five shell middens of different ages from the Jomon period (4900 BP) to the Ainu cultural period (800 BP), 107 animal bone samples were selected for radiocarbon measurements. The apparent age differences between Japanese deer and northern fur seal showed the clear effect of deep-water upwelling in this region. Our data showed relatively stable age differences from 4500 BP to 800 BP, with an estimated ΔR values around 380 14C yr. Results are consistent with previous estimation based on simulation models and oceanographic properties.
