Abstract
Reef-building corals physiologically mediate their calcifying fluid carbonate chemistry to promote skeletal growth. At the same time, trace elements are incorporated into the skeleton during calcification, which can be used to reconstruct past climate. I utilise geochemical approaches to constrain the calcifying fluid carbonate system dynamics, together with measurements of photo-physiology and calcification rates for seven coral species growing in Western Australia. I then evaluate the utility of three coral paleothermometers (Sr/Ca, Li/Mg, Sr-U) with respect to species effects. Overall, I demonstrate how the calcifying fluid carbonate-chemistry drives calcification rates and I show how these processes influence coral paleothermometry.
