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 ... -
Geoengineered Ocean Vertical Water Exchange Can Accelerate Global Deoxygenation
; ; (Geophysical Research Letters, 2020-08-12)
Ocean deoxygenation is a threat to marine ecosystems. We evaluated the potential of two ocean intervention technologies, that is, “artificial downwelling (AD)” and “artificial upwelling (AU),” for remedying the expansion ... -
Mixed Layer Depth Promotes Trophic Amplification on a Seasonal Scale
; ; ; ; ; ; (Geophysical Research Letters, 2022-06-16)
The Humboldt Upwelling System is of global interest due to its importance to fisheries, though the origin of its high productivity remains elusive. In regional physical‐biogeochemical model simulations, the seasonal amplitude ... -
Simulated Future Trends in Marine Nitrogen Fixation Are Sensitive to Model Iron Implementation
; ; ; ; ; ; (Global Biogeochemical Cycles, 2022-02-24)
Biological nitrogen fixation is an important oceanic nitrogen source, potentially stabilizing marine fertility in an increasingly stratified and nutrient‐depleted ocean. Iron limitation of low latitude primary producers ... -
Sinking of Gelatinous Zooplankton Biomass Increases Deep Carbon Transfer Efficiency Globally
; ; ; ; ; ; (Global Biogeochemical Cycles, 2019)
Gelatinous zooplankton (Cnidaria, Ctenophora, and Urochordata, namely, Thaliacea) are ubiquitous members of plankton communities linking primary production to higher trophic levels and the deep ocean by serving as food and ...
