Benaltabet and his colleagues propose a study of the dissolved aluminium and silicate fate in the Gulf of Aqaba (Red Sea).
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.
This study challenges the paradigm that dissolved aluminium in the bottom waters of the Arctic basins could result from a top-down process.
Farmer and colleagues review the geochemical proxies based upon sedimentary isotope ratios of three abundant biologically mediated elements.
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 […]
Large-scale distributions of dissolved zinc (Zn) in the western and central subarctic North Pacific Ocean was established as part of the North Pacific GEOTRACES section GP02. Kim and co-workers could […]
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 […]
The strong similarities between zinc (Zn) and silicon (Si) vertical profiles have led many studies to suggest the uptake of Zn in diatom frustules, followed by simultaneous remineralisation at depth. […]
Although this article is not resulting from GEOTRACES activity, its content is definitely GEOTRACES relevant. The authors constructed an up-to-date compilation of the continental silicon (Si) cycle, including the fate […]
Thanks to the most impressive set of dissolved aluminium (Al) and silicon (Si) data ever published in the Atlantic Ocean, Middag and co-workers (2015, see reference below) are thoroughly scanning […]
Roshan and Wu (2015, see reference below) reveal that the correlation between dissolved zinc (Zn) and silicon (Si) is relatively weak in the North Atlantic Ocean (GA03 US section). They […]
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 […]
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. […]
