Electron transfer (redox) reactions, mediated by soil microbiota, modulate elemental cycling
and, in part, establish the redox poise of soil systems. Understanding soil redox processes …

Details of Earth's shallow subsurface—a key component of the critical zone (CZ)—are
largely obscured because making direct observations with sufficient density to capture …

Anaerobic biodegradation of organic amendments and contaminants in aquifers can trigger
secondary water quality impacts that impair groundwater resources. Reactive transport …

Microbial reduction of Fe (III) can be one of the major factors controlling methane production
from anaerobic sedimentary environments, such as paddy soils and wetlands. Although …

Secondary water quality impacts can result from a broad range of coupled reactions
triggered by primary groundwater contaminants. Data from a crude-oil spill research site …

Landfilling remains the most attractive waste management method for solid waste. Although
not the most efficient and environmental-friendly option, landfills offer a cost-efficient solution …

An association of authigenic pyrite and gypsum has been found in deep-sea sediments from
a core retrieved on the continental slope of the Santos Basin, South Atlantic. Pyrite occur …

Geophysical investigations documenting enhanced magnetic susceptibility (MS) within the
water table fluctuation zone at hydrocarbon contaminated sites suggest that MS can be used …

Previous studies have linked biogeophysical signatures to the presence of iron minerals
