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 …

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 …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Distributions of dissolved and particulate rare earth elements (REEs) and seawater
neodymium isotopic composition (ε Nd) were established in samples from the BONUS …

Fractionation of silicon (Si) isotopes was measured in seven species (nine strains) of polar
and sub-polar marine diatoms grown in semi-continuous unialgal cultures under optimal …

Geological reservoir δ30Si values have increasingly been applied as paleoclimate and
paleoproductivity proxies. Many of these applications rely on the assumption that the surface …

The growth of siliceous phytoplankton, mainly diatoms, in the Southern Ocean influences the
preformed nutrient inventory in the ocean on a global scale. Silicic acid use by diatoms and …

The silicon isotope composition of opal frustules from photosynthesising diatoms is a
promising tool for studying past changes in the marine silicon cycle, and indirectly that of …

Both the nitrogen (N) isotopic composition (δ 15 N) of the nitrate source and the magnitude
of isotope discrimination associated with nitrate assimilation are required to estimate the …

A paradox is commonly observed in productive sea ice in which an accumulation in the
macro-nutrients nitrate and phosphate coincides with an accumulation of autotrophic …
