基于对39个主要由日本杉木（Cryptomeria japonica）组成的出土样品的9693次年度分解测量，我们提出了两个新的日本中部和北部的千年树轮氧同位素年代学。这些年代学是通过对日本中部和北部分别覆盖2349-1009 BCE（1341年）和1412-466 BCE（947年）的多个样品的树轮宽度和δ18O数据进行交叉测年而得出的。结合我们发表的日本中部年代学，目前可用的树木年轮δ18O数据集涵盖了过去4354年（公元前2349年至2005年），这是亚洲最长的树木年轮δ18O数据集。此外，Sakurai等人（2020）独立开发的14C含量的高分辨率时间记录，通过我们在公元前667-660年的年轮中对早期和晚期木材的14C测量再现。
We present two new millennium-long tree-ring oxygen isotope chronologies for central and northern Japan, based on 9693 annually resolved measurements of tree-ring oxygen isotopes from 39 unearthed samples consisting mainly of Japanese cedar (Cryptomeria japonica). These chronologies were developed through cross-dating of tree-ring widths and δ18O data from multiple samples covering the periods 2349–1009 BCE (1341 yr) and 1412–466 BCE (947 yr) for central and northern Japan, respectively. In combination with our published chronology for central Japan, the tree-ring δ18O dataset currently available covers the past 4354 yr (2349 BCE to 2005 CE), which represents the longest annually resolved tree-ring δ18O dataset for Asia. Furthermore, the high-resolution temporal record of 14C contents independently developed by Sakurai et al. (2020) was reproduced by our 14C measurements of earlywood and latewood in annual rings for the period 667–660 BCE.
