Central Arctic fertilization by the Transpolar Drift
Their findings highlight the importance of the Transpolar Drift in delivering dissolved silica and iron to feed low diatom primary production in the central Arctic Ocean.
Silicon Isotopes
Surprisingly heavy silicon isotopes in the surface and deep Arctic Ocean
Brzezinski and his colleagues report on a comprehensive study of the Arctic Ocean silicic acid concentrations and silicon isotopic composition…
Silicon isotopes reveal the different Arctic endmembers contributing to the deep water formed in the North Atlantic Ocean
Combining a multiparametric analysis, biogenic and dissolved silicon (Si) isotope data (30Si-bSiO2 and δ30Si-DSi, respectively) in the Arctic Ocean, Liguori and co-workers (2020, see reference below) could unravel the influence […]
GEOTRACES intercalibration of the stable silicon isotope composition of dissolved silicic acid in seawater
Dissolved silicon (Si) is a major oceanic nutrient and variations of its stable isotope values are reflecting the intensity of surface primary production. As for other isotopes, agreement between the […]
First major ocean sections of silicon isotopes
The GEOTRACES programme is providing the first major ocean sections of silicon isotopes, δ30Si, aiding efforts to use this proxy to reconstruct diatom silica production in both the modern and […]
What drives the silicon budget in the Bay of Bengal? The isotope composition clues…
The first data set of dissolved silicon isotope composition (δ30Si) along with concentrations (DSi) in seawater of the northern Indian Ocean is presented from the Bay of Bengal (BoB) region. […]
