Using Silicon Isotopes to Trace the Biogenic Silica in the Southern Ocean
… producers, are inextricably linked to the marine silicon (Si) and carbon (C) cycles. Diatoms are regarded as unicellular, eukaryotic organisms that form biogenic silica (bSi) frustules. The use of stable isotopes and physicochemical factors (temperature, light, and trace metal) provides a …

SILICON ISOTOPE AND PETROGRAPHIC INVESTIGATIONS OF SILICIFIED CARBONATE ROCKS: IMPLICATIONS FOR IMPROVED PARAGENETIC SEQUENCING AND PROXIES FOR PALEOZOIC OCEAN CHEMISTRY
… interest and application of the analyses of silicon isotopes in geologic studies, the silicon isotopic budget and cycle in ancient oceans is still poorly constrained. This study uses silicon isotopic data from silicified carbonate rocks to investigate their paragenesis and discusses the …

Tracking Changes In Silicon Isotopic Composition During Diatom Descent and Dissolution In the Cariaco Basin.
<p>We measured the Si isotopic composition (i.e. δ<super>30</super>Si) of sinking diatom opal in the Cariaco Basin to evaluate primary controls on diatom δ<super>30</super>Si values. The Cariaco Basin time series consists of four sediment traps at progressively greater depths on a single mooring …
