The amount of C in soil far exceeds the C content of atmosphere as well as the amount C stored above ground as plant biomass. The C fluxes between atmosphere and biomass are huge, many orders of…

Interactions of iron and organic matter as controls on the fate of permafrost carbon in the Arctic

Lead Institution

University of Michigan

Principal Investigator

Rose Cory

Project type

Large-Scale EMSL Research

The ongoing thawing of permafrost soils is the only environmental change that allows tremendous stores of organic carbon (C) to be converted into carbon dioxide (CO2) on relatively short time scales,…

Assessing Organo-metal and Organo-Mineral controls on Soil Organic Matter stabilization in B horizons using a diverse set of A horizons

Lead Institution

Environmental Molecular Sciences Laboratory

Principal Investigator

Nancy Hess

Soil organic matter (SOM) is transformed by microbial processes and transported through soils by water. SOM leached from A horizons and can be stabilized through mineral-organic and metal-organic…
