Example of in situ dead coral colonies sampled in this study.
(a) Faviid colony prior to sampling at Bramston Reef. The hammer in the photograph is 26cm in length; (b) Excellent preservation of corallite structure on many of the dead colony surfaces suggests minimal erosion; (c) Tabular Acropora sp. colony prior to sampling at Stone Island (width of sample bag in the photograph is 23cm) and (d) Subsample taken from the same colony for U-Th dating (Photographer: T. Clark).
