[1] 长期以来，温带地区的冰芯一直被认为有助于了解当地的气候趋势，但事实证明，可靠的年代测定方法很困难。在这里，我们表明，使用仅含 10 毫升水的样品测量花粉可以准确测量每年的冰积累量。此外，两种主要类型的花粉使我们能够估计夏季冰的积累以及年度积累。
[1] Ice cores from temperate regions have long been expected to be useful for understanding local climate trends, but a reliable dating method has proved difficult. Here we show that measurements of pollen using samples with only 10 mL of water can give an accurate measure of the annual ice accumulation. In addition, two major types of pollen allow us to estimate the summer ice accumulation as well as the annual accumulation.
