Abstract
This study includes seasonal layer study of Porites lutea using combination of alizarin staining and UV illumination methods and the correlation with climate data. The growth layers were recognized by using alizarin staining method, which was marked on live tissue of corals P. lutea. Under the UV-light, dark fluorescent layers represented the wet season (June to November) and light fluorescent layers corresponded to dry season (December to May). The results revealed that the alizarins integrated into newly forming skeleton which looks as pink color. The color remains as a permanent implant indicating the place of calcification during the experiment. Seasonal layers (wet and dry season) can be used to determine the skeletal growth thickness yearly, since the season cycles are relative regular in whole year. Recognizing and ascertaining the dark and light fluorescent layers were useful for retrospectives analysis of coral age prediction.
