| Research Abstract |
High resolution measurements of an organic compound, aspartic acid (Asp), from skeleton of modern coral samples suggest that the distinct seasonal pattern in Asp is closely related with growth (calcification) of coral skeleton and that Asp reflects the biological response of corals more faithfully. Cultivated corals showed that Sr/Ca was controlled primarily by sea surface temperature, while Mg/Ca mainly reflected the growth rate. Cultivated pearl mussel showed pearl calcification in wider range of temperature. Cultivated benthic foraminifera showed sharp decline
