Outline of Final Research Achievements

To reconstruct past marine environments for the last millenium at low-latitude, where paleoenvironmental information is limited, we collected modern and fossil coral skeletons from Ishigaki Island and determined ages, oxygen isotopic composition and minor metal concentrations.
We obtained total 1015 years coral records containing the periods of Little Ice Age as well as Medieval Climatic Anomaly.
