| Research Abstract |
Time-series observation of carbonate system at coral reef of Sesoko Island revealed that calcification rate of coral community around this island reaches to zero at PCO_2=945 ppmv in sea water. It is suggested that calcifying organisms in Sesoko coral reef will face to severe damage and that drastic change in ecosystem will be caused at the end of 21 century or later, according to the rapid prediction model of atmospheric CO_2 increase in IPCC report.
Coral incubation studies revealed the characteristic responses of coral metabolisms of photosynthesis-calcification to light-radiation stress, hazardous chemical stress, as well as responses of trace elements incorporation such as Sr, Mg and U into skeleton and of skeletal mineral formation of juvenile coral.
