Some recent GEOTRACES science findings are reported below.
The authors are proposing a radium-228 (228Ra) isotope mass balance for the upper Mediterranean Sea to estimate the magnitude of Submarine Groundwater Discharge (SGD) to this basin. Radium isotopes have […]
A new method for the determination of seawater lead (Pb) isotope compositions and concentrations was developed, which combines and optimizes previously published protocols for the separation and isotopic analysis of […]
Cobalt (Co) is an important micronutrient for many species living in the surface waters (bacteria, cyanobacteria, different types of phytoplancton…). Interestingly, the Co requirements vary between the different species and […]
High-resolution vertical profiles of neodymium (Nd) concentrations and isotopic compositions were measured at the eastern part of the US GEOTRACES North Atlantic Zonal Transect (GA03, Gulf of Cadiz – Mauritanian […]
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. […]
Two process studies (2008 and 2012) designed to study temporal changes in the biogeochemical cycling of iron (Fe), provide in situ results for dissolved and particulate Fe (DFe and PFe) […]
The four radium (Ra) isotopes (224Ra, 223Ra, 228Ra, 226Ra, “radium quartet”) are produced in situ via decay of their insoluble thorium isotope parents in sediments from the continental margins and […]
Twining and co-authors (2014, see reference below) used synchrotron x-ray fluorescence mapping to measure macronutrients such phosphorus (P), sulphur (S), and silicon (Si), and also trace metals like iron (Fe), […]
A detailed study of the dissolved and particulate iron (Fe) concentrations and isotopes off the Papua New Guinea coast is proposed. Regarding the sources, iron isotopic composition (δ56Fe) values reveal […]
