We aim to molecularly characterize the distribution of dissolved organic carbon (DOC) in wetland sediments via Fourier transform ion cyclotron resonance mass spectrometry (FTICR MS), and to link…

Biogeochemical and genomic determinants of methane cycling in freshwater wetland sediments

Lead Institution

Colorado State University

Principal Investigator

Kelly Wrighton

Project type

Large-Scale EMSL Research

Terrestrial freshwater wetlands are carbon rich environments that play a significant role in the global release of methane to the atmosphere. Our research provides an understanding of how methane…

Deciphering controls on plant decomposition in Arctic ecosystems: Identifying unknown microbial condensed tannin degradation pathways

Lead Institution

Colorado State University

Principal Investigator

Kelly Wrighton

Project type

FICUS Research

Climate change in the Arctic is progressing rapidly, and much of the focus, thus far, has been on permafrost thaw and the rapid mineralization of soil organic carbon (C) by soil microorganisms…

Life in the deep terrestrial subsurface: microbial metabolism before and after shale gas extraction

Lead Institution

Colorado State University

Principal Investigator

Michael Wilkins

Project type

Exploratory Research

Black shales underlay much of the continental U.S., and are a critical component of current and future energy resources. To extract hydrocarbons from these formations, shales are hydraulically…

Shales across scales: Identifying conserved biogeochemistry and microbial metabolism across geographically distinct deep subsurface ecosystems

Lead Institution

Colorado State University

Principal Investigator

Michael Wilkins

Project type

Large-Scale EMSL Research

The hydraulic fracturing of hydrocarbon bearing shales to yield oil and gas is now a critical part of the US energy portfolio. Microorganisms present in injected fluids colonize these environments,…

Methanogenesis in wetland soils: It may not always be as deep as we all thought

Lead Institution

Colorado State University

Principal Investigator

Kelly Wrighton

Project type

Large-Scale EMSL Research

This proposal focuses on understanding the constraints on methane metabolism in freshwater temperate wetland soils, as these systems currently represent the largest source of natural methane…

Multi-watershed perturbation-response traits derived through ecological theory

Lead Institution

Pacific Northwest National Laboratory

Principal Investigator

James Stegen

Project type

Large-Scale EMSL Research

This project will transform our ability to understand and predict how the influences of biogeochemical hot spots and hot moments on surface-subsurface systems are altered by disturbance. New theory…

Incorporating hydrologic perturbation and microbial processes into carbon budgets from coastal wetland soils

Lead Institution

Colorado State University

Principal Investigator

Kelly Wrighton

Project type

Large-Scale EMSL Research

Despite their relatively small land coverage, wetlands represent the largest natural source of atmospheric methane, a potent greenhouse gas. However, variations in these wetland emission budgets are…

Tracking the degradation of fresh particulate organic matter in permeable riverbed sediments using FT-ICR-MS and metagenomic/transcriptomic sequencing

Lead Institution

University of Wisconsin, Madison

Principal Investigator

Eric Roden

Project type

FICUS Research

The hyporheic zone, where groundwater and river water mix within riverine corridors, represents a highly active zone of biogeochemical cycling in which key transformations of many critical elements…
