| Research Abstract |
In this study, we examined bryozoans as a new environmental proxy. The result of bryozoans monitoring experiment in the field shows a clearly inverse correlation between bryozoan zooid sizes and MART(mean annual range of temperature). Furthermore, oxygen isotope variation is consistent with the fluctuation of average water temperature. Bryozoan skeletons, therefore, are useful as an environmental proxy.
