With these bands af growth rate indicatire, the cerai wes sectioned into yearly increnents and analyzed by low-level, sindectructive gamma epectrometry, radizchemical techniques. and mass spectrometry to retenstruct tre variavionrs in the cancentration of trarsuranics and other redicnuclides in the merine envirenment at Bibini since 1954. From che cancentration data retained in this indicator species, the e:change rate cf radicnuclides between the lagcan and the apen ccean is computed te te langer than exchange rates based on physical circulation data. There is na constant ratio of piutenium isetepes in the coral growth sections, suggesting that the redistributions af the several pluteniun iSttores in tne environment may be ceaverned ty different bicgeochemical precsszes.
