Particulate rare earth elements distributions, processes and characterisation of nepheloids in the North Atlantic

Lagarde et al. realised the first basin scale section of particulate rare earth elements concentrations across the North Atlantic Ocean.

Isopycnal mixing controls protactinium and thorium distributions in the Pacific Southern 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…

Time series thorium-230 data reveal scavenging intensification over the last 15 years in the Arctic Ocean

Authors demonstrate that the later hypothesis is likely explaining thorium-230-depletion in intermediate layers of the Amundsen basin.

Uranium-238 data and physical transports off the Peruvian coast are questioning the thorium-uranium export model

Authors determined insignificant advective and diffusive thorium-234 fluxes at 25 stations in the Peruvian oxygen minimum zone

When GEOTRACES‐based synthesis efforts improve global iron-cycling understanding

Using historical (1987-2007) and recent GEOTRACES data, authors compiled an impressive data set comprising dissolved, filtered and trap-collected particulate iron

Particulate trace element export in the North Atlantic Ocean

Authors estimated particulate trace element export fluxes and residence times in the upper North Atlantic Ocean

Surface water trace element and isotope data challenge dust flux models

Using measurements of dissolved and particulate thorium-230 and thorium-232 along a section across the South Pacific, authors estimated the dust flux over this remote area

Dissolved iron and manganese fates reveal processes along the hydrothermal TAG plume

Authors performed high-spatial resolution analyses of dissolved iron and manganese samples collected at the Mid Atlantic Ridge
