The PI will continue his work on high precision dating of carbonates and marine geochemistry of rare earth elements with multiple objectives in mind, including: the determination of chronology of marine carbonates of the past 400 K years; marine terraces and their relationship to sea-level changes; isotopic chemistry of pore waters and the effect of diagenesis on U-Th chronometer; abundance of Platinum and Silver in seawater; and geochemistry of Nd, U and Th. The work will help refine the C-14 time scale and the chronology of sea-level changes of the recent past.
