Paleoclimate from Coral Skeletons

Massive corals can grow for hundreds of years and record climatic and oceanographic conditions in the chemistry of their skeletons.  Long coral drill cores provide material for a broad array of geochemical analyses that reveal information about sea surface temperature, salinity, river runoff/dust input, and human activities including land-use change and pollution.  This project will involve measuring trace element (Sr/Ca and Ba/Ca) and/or oxygen isotopic ratios (d18O) in coral skeletons for reconstruction of climate in a region to be determined.
