Skeletons of massive corals are important recorders of climatic                 and environmental change. Density bands in coral skeletons can                  be used as chronometers much like tree rings, recording                         chemical information such as variations in carbon and oxygen                    isotopes. In spite of the great interest and importance of                      these features, little is known about how or why density bands                  form, and about the precise relationships between environmental                 parameters, coral physiology and the stable isotope                             composition. This project will study the control of stable                      carbon and oxygen isotopes and density banding in coral                         skeletons through carefully controlled laboratory experiments                   and routinely monitored field colonies. In the laboratory                       corals will be grown using seven different combinations of light                and temperature. Conditions of growth such as temperature,                      insolation, isotopic composition of the water, isotopic                         composition of food, and water composition will be continually                  measured. At the end of the experiment skeletal growth will be                  analyzed for density patterns and carbon and oxygen isotopes.                   Similar measurements will be made on a set of field colonies.
