Analysis of Mg, Sr, and Ba in deep sea corals using SIMS and ICP-MS

Abstract

Chemical compositons of corals are widely used to reconstruct the temperature and composition of the ocean. However, many corals are heterogeneous in minor and trace elements even when they grew at constant temperature and seawater composition. The goals of our work are to characterize and explain Mg, Sr, and Ba distributions across known skeletal features of corals, and to establish how these distributions vary with temperature.
