[MIS34-P16] Oxygen isotopic records of the stalagmite KA01 from Kiriana in Mie Prefecture, Japan
We studied the stalagmite KA01, a 35-cm-long specimen that has been formed from 12.6 ka to 1.3 ka. KA01 and some Chinese records share similar features, such as higher values around 12 ka, depressed intensity during 7-9 ka, and the trend change from increasing to decreasing at 2.8 ka. However, KA01 exhibits smaller amplitude of the isotopic change than the Chinese specimens. The reduced amplitude of KA01 was likely attributed to the shorter distance of the vapor transportation, which reflected on the condensation ratio. Thus, our isotopic profile of KA01 is probably more faithful record of the EASM and therefore can be valuable for considering the Holocene evolution of the East Asian climate system.
