Germanium/silicon and silicon isotope fractionation by marine diatoms and sponges and utility as tracers of silicic acid utilization
This research endeavoured to lay the groundwork in understanding the oceanic cycling of silicon (Si) during the past, with a particular focus on the Southern Ocean, using a multi-proxy and multi-organism approach. Two oceanographic tracers, one based on the fractionation of natural abundances of stable Si isotopes and the other based on the germanium:silicon ratio (Ge/Si), were examined in siliceous sponges and diatoms and their surrounding seawater. Specifically, this thesis attempts to...[Show more]
