Outline of Final Research Achievements |
Through this project, I have successfully enhanced the field of application of microscale isotopic analytical technique (MICAL3) to: (1) High precision and high sensitive stable isotopic analysis by using customized CF/DI-IRMS system for IsoPrime100. (2) Stable carbon and oxygen isotopic dispersions of individual foraminifera: new proxy to estimate the sea environmental condition precisely. (3) High-resolution stable isotopic analysis of CaCO3 to clarify the life history recorded in fish otolith. (4) Clarifying the impact of the concentrated heavy rain to coastal area: the result of monitoring the fluctuations of stable oxygen isotope of seawater.
