Advancing soil C characterization using HRMS and NMR

Lead Institution
Environmental Molecular Sciences Laboratory
Principal Investigator
Nancy Hess
Soil organic matter consists of diverse and complex mixture of hundreds to thousands biological and metabolic products that are poorly characterized using current techniques. We seek to develop a…

Pore- to Core-Scale Research to Inform Ecosystem-Scale Soil C Biogeochemistry

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Vanessa Bailey
Project type
Large-Scale EMSL Research
The spatial separation of soil organic carbon (SOC), microbes, and extracellular activity is an important mechanism of SOC protection in soils that exists at the soil pore (micron-mm) scale. The…

The Schizophyllum commune proteome

Lead Institution
Environmental Molecular Sciences Laboratory
Principal Investigator
Scott Baker
Project type
Exploratory Research
Background The authors, have in parallel with this proposal, submitted a genome sequencing proposal to the DOE Microbial Genome Program (MGP) for Schizophyllum commune (see attached pdf). This…

Establishment of a Robust Method for Soil Metabolomics Analysis

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Vanessa Bailey
Project type
Limited Scope
The objective of this work is to adapt current evolving protocols for metabolomics analyses to soil samples. As chemical perturbations are primarily detected on a molecular level, the metabolome will…

Enhancing C Sequestration in Terrestrial Ecosystems: Linking C and N cycling in soils (Part of Center for Research on Carbon Sequestration in the Terrestrial...., PNNL SCOPE # 30929).

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Vanessa Bailey
Project type
Exploratory Research
The objective of this research was to determine how N can control the C cycle in soils. We incubated soils from 5 different ecotypes with varying amounts of N and a fixed amount of C. At…

FSFA: MOSAIC—Metabolic and Spatial Interactions in Communities

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Errol Robinson
This EMSL user proposal is to support the MOSAIC DOE BER funded FSFA at PNNL. The primary activities involving EMSL are a set of BSSD demonstration tasks focusing on key science questions and related…

Microbial CH4 and CO2 Fluxes and C Stabilization Mechanisms in Soils

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Vanessa Bailey
Project type
Large-Scale EMSL Research
Current versions of the Community Land Model (CLM) do not represent the soil biogeochemical mechanisms controlling the fluxes of CO2 and CH4, two known greenhouse gases (GHG).. This failure is…

Effect of drought duration on C mineralization

Lead Institution
Pacific Northwest National Laboratory
Principal Investigator
Sarah Fansler
Drought and inundation events have been linked to increases in SOM availability and carbon mineralization. The duration of a drought event impacts the ability of the soil microbial community to…
