| Outline of Final Research Achievements |
Most of the terrestrial climate proxies in mid- and low-latitudes region are qualitative. Isotopic compositions of fluid-inclusion water in speleothems are promising tools, because they give quantitative information to reconstruct the past hydrological and temperature changes. Here, we have developed an isotope measurement technique for fluid inclusions in stalagmite, and applied the method to stalagmites in Okinawa, Japan. The developed system can measure the isotope ratios of fluid-inclusion water in nano-liter quantities. Data from the stalagmite samples of the modern and the last glacial period suggest that it is possible to reconstruct the past temperature.
