Constraining Global Marine Iron Sources and Ligand‐Mediated Scavenging Fluxes With GEOTRACES Dissolved Iron Measurements in an Ocean Biogeochemical Model
; ; ; ; ; ; ; ; (Global Biogeochemical Cycles, 2021-08-09)
Iron is a key micronutrient controlling phytoplankton growth in vast regions of the global ocean. Despite its importance, uncertainties remain high regarding external iron source fluxes and internal cycling on a global ... -
El Niño-Driven Oxygenation Impacts Peruvian Shelf Iron Supply to the South Pacific Ocean
; ; ; ; ; ; (Geophysical Research Letters, 2020)
Upwelling ocean currents associated with oxygen minimum zones (OMZs) supply nutrients fuelling intense marine productivity. Perturbations in the extent and intensity of OMZs are projected in the future, but it is currently ... -
Exploring the Iron-Binding Potential of the Ocean Using a Combined pH and DOC Parameterization
; ; (Global Biogeochemical Cycles, 2020)
The major part of dissolved iron (DFe) in seawater is bound to organic matter, which prevents iron from adsorptive removal by sinking particles and essentially regulates the residence time of DFe and its availability for ... -
Heavy Metal and Rock in Space: Cluster RAPID Observations of Fe and Si
; ; (Journal of Geophysical Research: Space Physics, 2021-03-22)
Metallic and silicate ions carry essential information about the evolution of the Earth and near‐Earth small bodies. Despite this, there has so far been very little focus on ions with atomic masses higher than oxygen in ... -
Seasonality of Organic Matter Degradation Regulates Nutrient and Metal Net Fluxes in a High Energy Sandy Beach
; ; ; ; ; (Journal of Geophysical Research: Biogeosciences, 2020)
During seawater circulation in permeable intertidal sands, organic matter degradation alters the composition of percolating fluids and remineralization products discharge into surficial waters. Concurrently, coastal seawater ...
