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.

Dissolved gallium unravels Pacific and Atlantic waters in the Arctic Ocean
Whitmore and co-workers demonstrate that the dissolved gallium distribution provide a better water source deconvolution than the nutrient tracers

Precise estimate of the mercury export from the Arctic to the Atlantic Ocean
Using new observations acquired during GEOTRACES Arctic cruises, a refined arctic mercury budget has been established

The biogeochemical ventures of dissolved iron and manganese across the Arctic Ocean
The spatial distributions and biogeochemical cycling of dissolved Fe (dFe) and dissolved manganese (dMn) across the Arctic Ocean were established during summer and fall 2015. The Canadian GEOTRACES transect extended […]

Arctic mercury export flux with marine particles higher than anticipated
In the ocean, the residence time of mercury (Hg), is largely driven by two removal mechanisms: evasion to the atmosphere and downward export flux with settling particles. The later was […]

Land inputs in the Arctic transported up to the North Pole
A new study found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean

Silicon isotopes reveal the different Arctic endmembers contributing to the deep water formed in the North Atlantic Ocean
Combining a multiparametric analysis, biogenic and dissolved silicon (Si) isotope data (30Si-bSiO2 and δ30Si-DSi, respectively) in the Arctic Ocean, Liguori and co-workers (2020, see reference below) could unravel the influence […]

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 […]
