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 …

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

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 …

A severe cyanobacterial bloom in the mainstem of a large Chinese river was first reported
from China. The Qiantang River is the longest river in the Zhejiang province, southeast …

Most aquatic systems show characteristic seasonal fluctuations in the total nutrient pool
supporting primary productivity. The nutrient dynamics essentially exacerbate critical …

We study the silicon biogeochemical cycle and its associated parameters in 24 and 18
Indian estuaries during dry and wet periods respectively. We focus more specifically on …

Silicon isotope values (δ 30 Si DSi) of dissolved silicon (DSi) have been analyzed in the
Lena River and its tributaries, one of the largest Arctic watersheds in the world. The …

Constraining the continental silicon cycle is a key requirement in attempts to understand
both nutrient fluxes to the ocean and linkages between silicon and carbon cycling over …

The use of silicon isotope ratios (expressed as δ 30 Si) as a paleolimnological proxy in
lacustrine systems requires a better understanding of the role of lake processes in setting …
