Coral skeleton density banding: biotic response to changes in sea surface temperature
Density bands in the CaCO3 (aragonite) skeleton of scleractinian corals are commonly used as chronometers, where crystalline couplets of high and low density bands represent the span of one year. Isotopic analysis of these density bands provides a sensitive reconstructive tool for paleoclimatology …

Chromatophore tissue density and skeletal density banding as a measure of the adaptive response of healthy corals to environmental change
… been drawn between changes in the tissue density of chromatophores and the development of skeletal density bands in “apparently healthy” corals (corals with no outward visible indication of distress or disease). An integrated histological and computed tomography x-ray diffraction (MicroCT) …

Carbon cycling in the Caribbean reef-building coral Orbicella: quantitative evidence for enzymatic control of skeletal density banding and coral-endosymbiont physiological plasticity during seasonal environmental change
… image analyses show that both the cellular density of zooxanthellae and the density of the chromatophores change according to positioning on the reef tract, and therefore levels of irradiance to which the host and endosymbiont are exposed. These results are correlated to the measured change …

Comparative Growth Rates of the Extinct Coral Montastraea nancyi: A Dominant Framework Builder in the Pleistocene (MIS 5e) Reefs of Curacao, Netherland Antilles
… to reveal well-preserved, regularly spaced density bands marking annual growth increments. Measurement of these growth increments provided the first growth rate data for M. nancyi from Curaçao, which can be compared to Pleistocene reefs elsewhere in the Caribbean. The mean growth rate (mm, …
