Abstract
We have analysed samples of the scleractinian coral Porites lutea from Mururoa by computerized tomography, a method that appears more reliab le than classic measurements of coral density. We correlate density me asurements with oxygen isotopic composition, and then with climatologi cal parameters (sea surface temperature and solar radiation). Wk demon strate that at the Mururoa site, solar radiation is the major factor i nfluencing the density pattern of the coral skeleton (i.e. calcificati on). However, the relationship between the density pattern and radiati on is neither simple nor linear.
