Gonzalez-Santana and his collaborators demonstrated that the oxidation kinetic of the samples combined with analysis of triplicate subsamples led iron (II) concentrations to decrease with time.
Authors present a comprehensive review of iron and iron isotope sources, internal cycling, and sinks in the ocean.
As part of the TONGA GEOTRACES process study, Tilliette and colleagues identified high dissolved iron concentrations in the west of the Tonga arc.
Tagliabue and his co-workers compare the hydrothermal dissolved iron simulated by both models.
Artigue and co-workers conducted a study to constrain how lithium and strontium from hydrothermal vents are dispersed in the ocean.
Venkatesh Chinni and Sunil Kumar Singh propose dissolved iron profiles along two meridional transects realized during spring and fall seasons between the Arabian Sea and the sub-tropical western Indian Ocean…
Authors performed high-spatial resolution analyses of dissolved iron and manganese samples collected at the Mid Atlantic Ridge
Roshan and collaborators present new observations of dissolved iron and its physical speciation in the South Pacific
As part of the GEOTRACES cruise GP15, Jenkins and co-workers (2020, see reference below) observed large water column anomalies in helium isotopes and trace metal concentrations above the Loihi Seamount […]
Joint Science Highlight with US-Ocean Carbon & Biogeochemistry (US-OCB). In a recent study, Ardyna et al (2019, see reference below) combined observations of profiling floats with historical trace element data and […]
The insoluble radiogenic isotopes of thorium (Th) are produced at a known rate in the water column via the decay of soluble uranium (234Th, 230Th) and radium (228Th) isotopes. These […]
Thanks to samples collected as part of the Japanese GEOTRACES cruise in 2009 – 2010, along section GI04, Takahata and co-workers (2018, see reference below) identified a maximum helium-3 ratios […]
For the first time, iron measurements in the Western Tropical South Pacific reveal that shallow hydrothermal inputs from the Tonga Arc region fertilize the euphotic waters of this vast region. […]
Waeles and co-authors (2017, see reference below) report for the first time on the dissolved-particulate partition of iron (Fe) after in situ filtration at the early stage of mixing of […]
The striking extension of the dissolved iron and manganese plumes over more than 4000 km from their hydrothermal sources along the US GEOTRACES East Pacific Zonal Transect (EPZT) cruise (GP16) has […]
Assessing the processes leading to dissolved iron (dFe) isotope fractionation in a hydrothermal plume is a key question, because it allows a better characterization of this specific source of dFe […]
High-quality dataset of dissolved zinc (Zn) from the US GEOTRACES EPZT cruise (GP16 section) allows Roshan and co-workers (2016, see reference below) to revisit the oceanic budget of dissolved Zn. […]
Data from the US GEOTRACES Eastern Pacific Zonal Transect (EPZT, GP16) demonstrate that lateral transport of hydrothermal iron, manganese and aluminium extends up to 4000 km west of the southern […]
The relative importance of four different dissolved iron (Fe) sources in the North Atlantic Ocean have been precisely determined for the first time thanks to GEOTRACES. Using a novel method […]
A large dissolved iron- and manganese-rich plume has been detected by Saito and co-authors over the slow-spreading southern Mid-Atlantic Ridge. This discovery calls into question the assumption that deep-sea hydrothermal […]
An unexpected radiogenic value of neodymium (Nd) isotopic composition observed by Catherine Jeandel and colleagues in the Deep Pacific Water raises the question of the role of mid ocean ridges […]
A North-South basin-scale full-depth section profile of dissolved Fe was realized in the Indian Ocean, as part of the first GEOTRACES Japanese cruise (Nov 2009 – Jan 2010). The data […]
