The silicon isotope composition of biogenic silica (δ 30 Si BSi) in the ocean is a function of
the δ 30 Si of the available dissolved Si (DSi; H 2 SiO 4), the degree of utilisation of the …

Silicon (Si) is the second most abundant element in the Earth's crust and is an important
nutrient in the ocean. The global Si cycle plays a critical role in regulating primary …

Silicon isotopes have considerable potential as proxy for (near-) surface processes and
environmental conditions. However, unambiguous interpretations of isotope signatures in …

In contrast to many other stable isotopes of the elements discussed in this book, those of
silicon are not strictly speaking “Non-Traditional Stable Isotopes” because they have been …

This paper provides an overview of stable isotope analysis (H, C, N, O, Si) of the macro-and
microscopic remains from aquatic organisms found in lake sediment records and their …

Phytoplankton cellular elemental quotas are important for evaluating the coupling of nutrient
cycles and assessing nutrient limitation in the ocean. While cell element quotas have been …

Benthic fluxes of dissolved silicon (Si) from sediments into the water column are driven by
the dissolution of biogenic silica (bSiO 2) and terrigenous Si minerals and modulated by the …

Silicon (Si) phases such as biogenic silica, lithogenic silicate and authigenic silica/silicate in
marine sediments provide valuable information about past Si cycling. Wet-chemical …

Glaciers and ice sheets are experiencing rapid warming under current climatic change and
there is increasing evidence that glacial meltwaters provide key dissolved and dissolvable …

The abrupt onset of Antarctic glaciation during the Eocene–Oligocene Transition (∼ 33.7
Ma, Oi1) is linked to declining atmospheric pCO 2 levels, yet the mechanisms that forced …
