Abstract

The skeletal banding observed in vertical cross-sections of two species of coral, Montastrea annularis from Jamaica and Diploria labrynthiformis from Bermuda, has been confirmed to be annual by ingrowth of ²²⁸ Th towards radioactive equilibrium with ²²⁸ Ra taken up from seawater. In addition the Bermuda coral is shown to have incorporated ²¹⁰ Pb at essentially constant specific activity over at least the last thirty years.

The individual annual patterns of growth banding in a suite of specimens of D. Labrynthiformis from Bermuda are shown to be correlative. The mass of CaCO ₃ accumulated each year is positively correlated with the band width for the corresponding year.
