Tracing and constraining anthropogenic aerosol iron fluxes to the North Atlantic Ocean using iron isotopes [PDF]
Nature Communications, 2019 The relative importance of crustal vs. anthropogenic dust deposition for iron cycling in the surface ocean is unclear. Based on analysis of iron isotope data from North Atlantic aerosol samples, the authors can reveal the relative importance of ...

Constraints on the Cycling of Iron Isotopes From a Global Ocean Model. [PDF]
Global Biogeochem Cycles, 2021 Although iron (Fe) is a key regulator of primary production over much of the ocean, many components of the marine iron cycle are poorly constrained, which undermines our understanding of climate change impacts.

Novel Insights into Marine Iron Biogeochemistry from Iron Isotopes
Annual Review of Marine Science, 2023 The micronutrient iron plays a major role in setting the magnitude and distribution of primary production across the global ocean. As such, an understanding of the sources, sinks, and internal cycling processes that drive the oceanic distribution of iron is key to unlocking iron's role in the global carbon cycle and climate, both today and in the ...

Correlated iron isotopes and silicon contents in aubrite metals reveal structure of their asteroidal parent body [PDF]
Scientific Reports, 2021 Iron isotopes record the physical parameters, such as temperature and redox conditions, during differentiation processes on rocky bodies. Here we report the results of a correlated investigation of iron isotope compositions and silicon contents of ...

Discovery of the iron isotopes [PDF]
Atomic Data and Nuclear Data Tables, 2010 Twenty-eight iron isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented.

Fractionation of iron species and iron isotopes in the Baltic Sea euphotic zone [PDF]
Biogeosciences, 2010 To indentify sources and transport mechanisms of iron in a coastal marine environment, we conducted measurements of the physiochemical speciation of Fe in the euphotic zone at three different locations in the Baltic Sea.

Nonbiological Fractionation of Iron Isotopes
Science, 2000 Laboratory experiments demonstrate that iron isotopes can be chemically fractionated in the absence of biology. Isotopic variations comparable to those seen during microbially mediated reduction of ferrihydrite are observed. Fractionation may occur in aqueous solution during equilibration between inorganic iron complexes. These findings provide insight

Metal-driven anaerobic oxidation of methane and the Sturtian deglaciation [PDF]
Nature CommunicationsThe Sturtian and Marinoan glaciations shaped Neoproterozoic palaeoenvironmental evolution. While methane emission likely intensified the Marinoan greenhouse effect, its role during the Sturtian glaciation—coinciding with widespread iron formations (IFs ...

Iron absorption and loss, and efficacy of iron supplementation with and without prebiotics in children with virally suppressed HIV: three prospective studies in South Africa [PDF]
Nature CommunicationsChildren living with HIV are at risk for iron deficiency, yet optimal strategies for prevention and treatment remain unclear. Here, we investigate iron absorption, losses, and the efficacy and safety of oral iron supplementation with versus without ...
