Seasonal and spatial variability in northern Gulf of Alaska surface-water iron concentrations driven by shelf sediment resuspension, glacial meltwater, a Yakutat eddy, and dust

Editors' Highlight—

This paper examines the transfer of iron (Fe) from shelf to ocean in a high latitude environment. It is based on data collected from three research cruises in the northern Gulf of Alaska along a transect from the mouth of the Copper River to beyond the shelf break. The authors discuss Fe supply processes from three main sources – shelf sediment, glacial meltwater and atmospheric dust – as well as their spatial and seasonal variation. Their 1D model provides a holistic overview of the sources and sinks of Fe and should be of interest to a wide range of scientists who work on nutrient and Fe supply to high latitude shelf systems.
