During the last decades investigations have explored large variations in silica (Si) fluxes related to varying climate conditions and human activity. My PhD project is focusing on the transition between the terrestrial and the marine Si cycles. The aim of the study is to learn more about the variability in Si delivery and the accumulation of Si in coastal sediments.
Therefore I will investigate the sediment record of the Chesapeake Bay that comprise the continental Si fluxes over long timescales (Holocene). Changes in silica isotope signals (δ30Si) will provide information about the variation of Si cycling through time and the effects of climate and human induced land use changes on Si redistribution.
