– New data on oceanic rare earth elements concentrations and neodymium isotopic compositions (3 papers)
 |
Early 2014 was favourable to the publication of new data of rare earth elements (REE) concentrations and neodymium (Nd) isotopic compositions in extreme areas of the ocean: the southern Atlantic Ocean, the northeast Corner of the Pacific Ocean and the remote south Pacific Ocean….

– Latest discoveries in zinc concentrations and isotopes in the ocean (4 papers)
 |
Zinc (Zn) is an essential micronutrient for phytoplankton and plays a key role in the productivity of the oceans. Despite the importance of this element, the processes which govern its cycling in the ocean are poorly understood. Thanks to GEOTRACES, an unprecedentedly large volume of data has been reported, revealing fascinating results…

– The potential of anthropogenic 236-uranium as a new and transient oceanographic tracer demonstrated in the North Atlantic
 |
236-Uranium (236U) is present on Earth due to natural and anthropogenic production. However, the estimated inventory of anthropogenic 236U (106 kg) largely exceeds the natural one (30 kg). Releasing even a tiny fraction of this artificial isotope would drastically change the environmental 236U/238U ratio and therefore make this ratio a useful isotopic marker to trace such anthropogenic releases and to study seawater transport and mixing processes in the ocean…
