Science Highlights
The development of the modern Antarctic Circumpolar Current occurred much later than previously thought!
This study is challenging the belief that the onset of the Antarctic Circumpolar Current was solely triggered by the opening and deepening of Southern Ocean Gateways.
Science Highlights
Overlooked riverine contributions of dissolved neodymium and hafnium to the Amazon estuary and oceans
Xu and colleagues investigated the isotopic composition of dissolved neodymium and hafnium along the entire salinity gradient of the Amazon estuary.
Science Highlights
Exhaustive modelling study of the oceanic neodymium parameters
The conclusion of this study reinforces the important role of the solid particles in driving the neodymium oceanic cycle.
Science Highlights
Updated compilation of the global continental and marine lithogenic neodymium isotopic measurements
This new compilation and gridded datasets offer a concrete way forward to improve the application of neodymium isotopes as a useful tracer of ocean circulation.
Science Highlights
Rare Earth Elements and neodymium isotopes as tracers in the Mediterranean Sea
Garcia-Solsona and co-workers analysed 9 seawater stations around the central Mediterranean Sea
Science Highlights
Particulate fluxes and circulation in a changing Arctic Ocean: tracer data and modeling
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 […]
