When titanium is not always behaving as a lithogenic conservative tracer: an Amazon estuary story
They established the distribution of titanium in Amazon and Pará rivers and their related plume during the high discharge period.
Colloids
Deep sea lithogenic weathering a source of iron colloids for the ocean
Homoky and co-workers determined the isotope composition of dissolved iron profiles in shallow surface sediments of the South Atlantic Uruguayan margin…
A new model simulates the speciation and dispersion of hydrothermal iron
Roshan and collaborators present new observations of dissolved iron and its physical speciation in the South Pacific
The Colloidal Hourglass: North Atlantic Iron Distribution Controlled by Dynamic Colloidal Phase
K. Kunde and colleagues (2019, reference below) show that a highly dynamic colloidal iron phase in the upper ocean and at the seafloor boundary controls the distribution of dissolved iron […]
