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

Lead Institution

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,…

Limited Scope

Black carbon is the residual, charred vegetation remaining after wildfires or biomass burning in terrestrial ecosystems. This large pool of carbon is more recalcitrant to microbial degradation in…

Sunlight exposure replaces the function of microbial enzymes needed to degrade DOM

Principal Investigator

Byron Crump

Project type

FICUS Research

About half of the dissolved organic matter (DOM) released from land is converted to CO2 in inland waters (e.g., streams, rivers, lakes), driving a CO2 flux to the atmosphere roughly equal to the net…

The fate of newly exposed carbon in the Arctic - controls on release to the atmosphere and transport to the ocean

Limited Scope

In the last 10 years the increasing heat of debate on how climate-change impacts to the Arctic will feed back to affect global temperatures has mirrored the arctic warming itself. Tremendous stores…

Project type

Large-Scale EMSL Research

The carbon (C) in thawing permafrost soils may have global impacts on climate change, yet the controls on processing and fate of this newly released C are poorly understood. Inland waters are…

Decoding DOM degradation: how does carbon source and sunlight exposure alter microbial metabolism and expression of genome-encoded metabolic degradation of permafrost organic matter?

Climate change in the Arctic is progressing rapidly, thawing large areas of permafrost that contain nearly half of the world's soil organic carbon. Conversion of this carbon pool to greenhouse…
