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 …

Climate change has a strong impact on ecosystem health, particularly in marginal seas such
as the Baltic, for example causing the spreading of anoxic areas (oxygen-free areas, the so …

Porewater dissolved silicic acid (DSi) concentrations and stable Si isotope compositions
(δ30Si) together with biogenic silica (bSiO2) contents of sediments in five sediment cores …

Studies of silicon (Si) isotope fractionation during diatom growth in open ocean systems
have documented lower Si isotopic values (δ 30 Si) in the biogenic silica of diatom frustules …

The cause of massive blooms of Ethmodiscus rex laminated diatom mats (LDMs) in the
eastern Philippine Sea (EPS) during the Last Glacial Maximum (LGM) remains uncertain. In …

Biogeochemical Si cycle in coastal areas is of vital importance due to its close link with the
carbon cycle. However, the coastal Si cycle has been heavily perturbated by human …

Si fluxes from the continents to the ocean are a key element of the global Si cycle. Due to the
ability of coastal ecosystems to process and retain Si, the 'coastal filter'has the potential to …

Although bottom water hypoxia (O 2< 2 mg L− 1) is presently widespread in the Baltic Sea
coastal zone, there is a lack of insight into past changes in bottom water oxygen in these …

This study presents a method for high‐precision Si isotope measurement of soil and
sediment reference materials using multi‐collector inductively coupled plasma‐mass …
