Permafrost thaw will release additional carbon dioxide into the atmosphere resulting in a positive feedback to climate change. However, the mineralization dynamics of organic matter (OM) stored in permafrost-affected soils remain unclear. We used phy

The paradigm that permafrost-affected soils show restricted mineral nitrogen (N) cycling in favor of organic N compounds is based on the observation that net N mineralization rates in these cold climates are negligible. However, we find here that thi

Carbon sequestration in soils has rarely been observed at microscopic scales. Here the authors reveal the impact of soil moisture regimes in shaping carbon stabilization and mineralization patterns tied to the pore network.

Microbial reduction and dissolution of reactive iron (III) mobilizes mineral-bound organic carbon, which contributes to carbon dioxide production and promotes methanogenesis and methane emission before complete permafrost thaw, according to an observ

South Patagonian speleothems yield chemical volcanogenic signals and tephra, which can be used to date regional volcanic eruptions and correlate them with the existing tephrochronology, according to geochemical analyses and micro-/nanoscale observati

The fate of soil carbon is controlled by plant inputs, microbial activity, and the soil matrix. Here the authors extend the notion of plant-derived particulate organic matter, from an easily available and labile carbon substrate, to a functional comp

Abstract Clay minerals and pedogenic metal (oxyhydr)oxides are the most reactive soil mineral constituents controlling the long-term persistence of organic carbon (OC) in terrestrial ecosystems. However, their co-occurrence in most soils complicates

Iron minerals trap carbon in permafrost, preventing microbial degradation and release to the atmosphere as CO2, but the stability of this carbon as permafrost thaws is unclear. Here the authors use nanoscale analyses to show that thaw conditions stim

Water-extractable organic carbon (WEOC) is considered as the most important carbon (C) source for denitrifying organisms, but the contribution of individual organic matter (OM) fractions (i.e., particulate (POM) and mineral-associated (MOM)) to its r
