The findings demonstrate that glacial retreat and loss of ice-shelves may potentially result in increases in dissolved iron supply to surface waters downstream of large marine terminating glaciers in future.

When lateral advective transport explains between 80 and 100% of the dissolved aluminium distribution
The results evidence that the effect of advection cannot be neglected in areas where a conjunction of significant horizontal dissolved aluminium gradients and significant horizontal currents is found.

Spatial and temporal variability of bioactive trace metals, speciation and organic metal-binding ligands in the eastern Gulf of Mexico
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.

Thorium-Protactinium fate across the tropical Atlantic Ocean: what reveals the water column-sediment coupling
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.

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 […]

Icebergs; a huge but highly variable source of iron to the ocean
Icebergs have been speculated to constitute one of the largest fluxes of iron (Fe) into the polar oceans since the 1930s and thus recent increases in ice discharge around the […]
