The geologic history of marine dissolved organic carbon from iron oxides Open
Dissolved organic carbon (DOC) is the largest reduced carbon reservoir in modern oceans 1,2 . Its dynamics regulate marine communities and atmospheric CO 2 levels 3,4 , whereas 13 C compositions track ecosystem structure and autotrophic me…

High-Precision Oxygen-Isotope Analysis of Iron (Oxyhydr)oxides Using High-Temperature Conversion Isotope Ratio Mass Spectrometry Open
We introduce a novel high-precision method for oxygen-isotope analysis of iron (oxyhydr)oxides using high-temperature conversion isotope ratio mass spectrometry (HTC-IRMS). In this approach, a finely ground mixture of iron (oxyhydr)oxide a…

Cavity Ring-Down Spectroscopy Performance and Procedures for High-Throughput δ18O and δ2H Measurement in Water Using “Express” Mode Open
Cavity ring-down spectroscopy (CRDS) is rapidly becoming an invaluable tool to measure hydrogen (δ²H) and oxygen (δ 18 O) isotopic compositions in water, yet the long-term accuracy and precision of this technique remain relatively underrep…

Nuclear spin effects in biological processes Open
Traditionally, nuclear spin is not considered to affect biological processes. Recently, this has changed as isotopic fractionation that deviates from classical mass dependence was reported both in vitro and in vivo. In these cases, the iso…

Global warming accelerates soil heterotrophic respiration Open
Carbon efflux from soils is the largest terrestrial carbon source to the atmosphere, yet it is still one of the most uncertain fluxes in the Earth’s carbon budget. A dominant component of this flux is heterotrophic respiration, influenced …

Cathodoluminescence of iron oxides and oxyhydroxides Open
Iron oxides and oxyhydroxides show promise as superconductor materials and as repositories of paleo-environmental information. However, there are no microscale non-destructive analytical techniques to characterize their combined mineralogy…

Strong evidence for a weakly oxygenated ocean–atmosphere system during the Proterozoic Open
Significance Earth’s transition from anoxic oceans and atmosphere to a well-oxygenated state led to major changes in nearly every surficial system. However, estimates of surface oxygen levels in the billion years preceding this shift span …
