Traill and co-workers used an extended optimum multiparameter analysis water‐mass mixing model to determine the interplay between physical and biological processes, and sources/sinks driving dissolved iron distributions…
Numerical models are some of the principal tools for understanding the cycling of geochemical and biogeochemical tracers in the ocean…
Alessandro Tagliabue exposes how ocean modelling must evolve to take the biological complexity of the surface ocean into account.
Levier and colleagues analysed dissolved and particulate protactinium-231 in samples collected in a section in the Southern Ocean…
Mete and colleagues used machine learning to predict the global distribution of oceanic barium…
The conclusion of this study reinforces the important role of the solid particles in driving the neodymium oceanic cycle.
Huang and co-workers propose the first data-driven surface-to-seafloor dissolved iron climatology.
Tagliabue and his co-workers compare the hydrothermal dissolved iron simulated by both models.
Xiang and co-workers compiled full ocean-depth size-fractionated particle data from three recent U.S. GEOTRACES cruises.
In this study, radium is used as a tracer for the waters of the Amazon that mix with those of the Atlantic Ocean.
Xu and Weber developed a data-assimilation model of the aluminum oceanic cycle.
Oka and colleagues demonstrate that the global distribution of REE can be reproduced by considering the internal cycle associated with reversible scavenging and external REEs inputs around continental regions.
Using available observations of dissolved copper, artificial neural networks, and an ocean circulation inverse model, authors calculated a global estimate of the 3-dimensional distribution and cycling of dissolved copper in the ocean.
Roshan and collaborators present new observations of dissolved iron and its physical speciation in the South Pacific
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 […]
A complete review of published and new water column profiles of thorium-230 (230Th) and protactinium-231 (231Pa) concentrations and neodymium (Nd) isotopic compositions collected in the Amerasian Basin of the Arctic […]
Lauderdale and co-authors (2020, see reference below) are seriously questioning the paradigm establishing that marine phytoplankton growth is limited by iron on a global scale. Iron availability to marine microbes […]
The importance of the cycle and speciation of nitrate and its isotopes (δ15N) in the ocean does not have to be demonstrated anymore. In an attempt to overcome the difficulty […]
What explains the hitherto mysterious correlation between zinc (Zn) and silicon, an element not involved in the Zn cycle? Roshan and co-workers (2018, see reference below) used an artificial neural […]
Thorium-230 (230Th) and protactinium-231 (231Pa) are two geochemical tracers extensively used for investigating particle transport in the ocean and reconstructing past ocean circulation. A key feature in reproducing their distributions by […]
Chemical species are constantly exchanged between seawater (solution, D) and particles (solid material, P). This continuous D-P exchange is a key process determining the chemical composition of the ocean. Particles […]
Marco van Hulten and co-workers (2017, see reference below) ran a global ocean model to understand manganese (Mn), a biologically essential element. The model shows that: (i) in the deep […]
Insoluble thorium (Th) isotopes are particle reactive while their radioactive parents are fairly soluble. This difference of behaviour has allowed chemical oceanographers to use Th isotopes to develop understanding about […]
Alessandro Tagliabue and co-workers (2016, see reference below) have conducted the first intercomparison of 13 global ocean iron models against the latest datasets emerging from GEOTRACES. A large disparity in […]
The dissolved Rare Earth Elements (dREE) data discussed by Zheng and co-workers (2016, see reference below) have been collected along a full depth section at 12°S in the South Atlantic […]
The terrigenic helium isotope distribution was simulated for the first time in the whole Mediterranean Sea, using a high-resolution model (NEMO-MED12) at one-twelfth of a degree horizontal resolution (6–8 km). […]
For the first time, a numerical study proposes the simulation of the anthropogenic tritium (3H) invasion as well as the distribution of its decay product helium-3 (3He) using a high-resolution […]
Phoebe Lam and Olivier Marchal (2015, see reference below) propose to describe, with the same model, the dynamics of particles in the oceanic water column and its effects –on four […]
Taking into account most of the parameters that govern any trace element’s oceanic behaviour is a challenge, given their number and complexity. Marco van Hulten and co-workers (2014, see reference […]
Using model simulations, Tagliabue and co-authors (2014, see reference below) tested the sensitivity of the ocean to absorb the atmospheric carbon dioxide (CO2) in response to variable supply of iron. […]
