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.

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.
Is the global primary production at it’s maximum rate?
Lauderdale and co-authors (2020, see reference below) are seriously questioning the paradigm establishing that marine phytoplankton growth is limited by iron on a global scale. Iron availability to marine microbes […]
Can phytoplankton help us determine the bioavailability of iron in the world ocean?
Joint Science Highlight with US Ocean Carbon and Biogeochemistry (OCB). Iron (Fe) is a key element to life but in seawater it is present at extremely low concentrations. The scarcity […]
