Long term records of atmospheric radiocarbon provide a wealth of information, both as records of carbon cycling in the environment and as a basis for all 14C dating. The Holocene atmospheric radiocarbon record is provided by tree rings and is considered to be (almost) robust. However, that of the period from 12,410 to c.26,000 BP is based on marine sediments which are influenced by the marine reservoir effect. Also, the corresponding information for the atmosphere for the period 26,000 to 50,000 BP is lacking. This project will establish a radiocarbon calibration model for the Late Pleistocene (10,000 / 50,000 BP) based on terrestrial material, mostly deciduous tree leaf fossils which are free from marine reservoir effects, recovered from the annually laminated lacustrine sediments of Lake Suigetsu, Japan. The project will also produce quantitatively reconstructed climate changes of the Monsoon regions for the last 150,000 yeas using high or ultra-high resolution pollen records. The profile will be established using tie-points such as geomagnetic excursions and tephra layers. The project will therefore contribute to international scientific endeavour in using radiocarbon-based information to determine the timing and rates of environmental changes, as well as understanding past changes in the global carbon cycle. The project will also contribute to hypothesis testing about the causal mechanisms of climate change, especially concerning the relative timing of D/O events in Asia, North Atlantic, Antarctica and many other marine and terrestrial records through the last glacial-interglacial cycle.

大气放射性碳的长期记录提供了丰富的信息，既可以作为环境中碳循环的记录，也可以作为所有14C定年的基础。全新世大气放射性碳记录由树木年轮提供，被认为是（几乎）可靠的。然而，从12410年到26000年期间BP是建立在受海洋储层效应影响的海洋沉积物基础上的。同时，缺少26000 ~ 50000 BP的大气信息。本项目将以日本水越湖年度层状湖泊沉积物为研究对象，以不受海洋储层影响的落叶树叶化石为主要材料，建立晚更新世（10,000 / 50,000 BP）放射性碳定标模型。该项目还将利用高分辨率或超高分辨率花粉记录，定量重建过去15万年的季风区气候变化。剖面将利用地磁偏移和地磁层等连接点建立。因此，该项目将促进国际科学努力，利用基于放射性碳的信息来确定环境变化的时间和速率，以及了解过去全球碳循环的变化。该项目还将有助于检验关于气候变化因果机制的假设，特别是关于亚洲、北大西洋、南极洲和许多其他海洋和陆地记录在末次冰期-间冰期的D/O事件的相对时间。
