Actinium-227, radium-226 and radium-228 profiles in sediments were measured and modeled at 5 stations in the Northeast Pacific…
Authors present a comprehensive review of iron and iron isotope sources, internal cycling, and sinks in the ocean.
Liu and her colleagues investigated dissolved trace metals distributions within the Benguela Upwelling System sampled from GEOTRACES GA08 cruise.
Hayes and colleagues have combined data to estimate how important North African dust could be as a source of iron to the Gulf of Mexico.
Among other findings, authors find that the new opal flux is roughly a factor of two increase over previous estimates having important implications for the global silicon cycle.
This study provides one of the first mechanistic explanations for Last Glacial Maximum deep ocean deoxygenation.
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.
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 […]
During the Last Glacial Maximum, the deep southern Pacific waters were stratified, efficiently accumulating old, CO2 rich waters. Basak and co-authors (2018, see reference below) measured neodymium isotopes in sediment […]
This work highlights the importance of the sedimentary source of dissolved Rare Earth Elements (REE) to the oceanic waters. Indeed, strong subsurface REE concentration maxima are evidenced in pore fluids […]
