Some recent GEOTRACES science findings are reported below.
Oka and colleagues demonstrate that the global distribution of REE can be reproduced by considering the internal cycle associated with reversible scavenging and external REEs inputs around continental regions.
This study demonstrates the importance of biology and ecology to understanding iron biogeochemistry.
This study provides one of the first mechanistic explanations for Last Glacial Maximum deep ocean deoxygenation.
Mellett and Buck present the concentrations of bioactive trace metals (Fe, Cu, Mn, Zn, Co, Ni, Cd, and Pb), Fe-and Cu-binding organic ligands, and electroactive Fe-binding humic substances in the eastern Gulf of Mexico.
Twenty seawater profiles and twenty core-top 231-protactinium and 230-thorium analyses were realised by Ng and colleagues along five depth transects across the northern tropical Atlantic open ocean.
Using available observations of dissolved copper, artificial neural networks, and an ocean circulation inverse model, authors calculated a global estimate of the 3-dimensional distribution and cycling of dissolved copper in the ocean.
Lagarde et al. realised the first basin scale section of particulate rare earth elements concentrations across the North Atlantic Ocean.
Pavia and co-workers determined the physical and chemical speciation as well as the vertical distribution of Protactinium-231 and Thorium-230 at 12 stations across the Southern Pacific Antarctic Circumpolar Current…
Authors demonstrate that the later hypothesis is likely explaining thorium-230-depletion in intermediate layers of the Amundsen basin.
