Abstract
Coral skeletons provide excellent high-resolution archives of past environmental conditions. Analysis of the nitrogen composition of the coral skeleton is an emerging tool for understanding the health and productivity of corals. This thesis examined nitrogen isotopic composition of coral skeletons through time. Two past thermal bleaching events in the Great Barrier Reef were inferred to have occurred during 1947 and 1965-68 by applying this approach. Evidence of long tissue turnover rates and bidirectional nitrogen exchange between the coral and zooxanthellae partners (fed heterotrophically) was also found when their tissue δ15N signatures were analysed.
