My PhD project is focusing on the changes in global ocean silica (Si) compositions through geological time. The major goal of this study is to understand the interactions between biosilification in organisms and the oceans and how these interactions have evolved through Earth’s history. I will investigate sediment records from different oceans using Si stable isotopes ratios on siliceous fossils (sponge spicules and diatoms) to address changing Si concentrations.
Moreover, changes in the oceanic DSi concentrations will provide information about the variation of Si cycling over long timescales and the effects on climate.
