Strong lithogenic imprints in the Indian Ocean waters
Ueki and co-authors reported the first sectional distributions of zirconium, hafnium and niobium along a north-south track in the Indian Ocean.

Dissolved manganese distribution in the Arabian Sea reveals many variable triggers
Analysis of dissolved manganese on samples collected on GEOTRACES cruises allowed Singh and colleagues to establish its basin-wide distribution in the Arabian Sea.
Insight on the aluminium cycling during the inter-monsoon period in the Arabian Sea and Equatorial Indian Ocean
Full vertical water column profiles were established by Singh and Singh along the GI05 transect in the Indian Ocean during the fall inter-monsoon period in 2015.
Specific features characterize the dissolved iron distribution in the North Western Indian 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…
Welcome to the first Korean participation in GEOTRACES
Thanks to the newly launched research vessel (R/V) Isabu of the Korea Institute of Ocean Science and Technology (KIOST), and the acquisition of a contamination-free PRISTINE (NIOZ, NL) ultraclean seawater sampling system […]
Helium-3 plumes in the deep Indian Ocean confirm hydrothermal activity
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 […]
High particulate organic carbon export in the Arabian Sea
In the framework of Indian GEOTRACES cruise GI02, high-resolution sampling was carried out in the Arabian Sea and the Indian Ocean during April–May 2014. The first 234Th-based carbon export flux […]
Estuary solid loads and solid-solution exchanges yield considerable dissolved trace metal enrichments
Based on a thorough investigation of water and suspended sediment samples collected over two years and a six seasons, Samanta and Dalai (2018, see reference below) show that the annual […]
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. […]
Tracking the Indian Ocean source of barium
Intermediate waters of the Bay of Bengal can be a significant source of dissolved barium (Ba) to the Indian Ocean. This is the conlusion of an extensive study of the […]
Substantial intra-basin variation of the dissolved metal/phosphorus ratio in the different water masses of the Indian Ocean
The first simultaneous, full-depth, and basin-scale section-distribution of dissolved (D) aluminum (Al), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) is […]
Dissolved cobalt enrichments over the Kerguelen plateau confirm that most of the natural fertilization is due to partial dissolution of local basalts
Exceptionally high dissolved cobalt (Co) concentrations have been measured in the surface waters above the Kerguelen Plateau (KEOPS), and in intermediate and deep waters above its eastern slope. Lateral advection […]
Significant role of dissolved/particulate neodymium from the Ganga–Brahmaputra river system and Bay of Bengale margin in contributing to the dissolved Nd budget of the global oceans.
Data on dissolved Nd concentrations and isotopic compositions measured along a 87 E transect (GI01 section, “Indian GEOTRACES”) have been used in an inverse model in order to identify the […]
Hydrothermalism: A significant dissolved iron source for the deep waters ?
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 […]
