Lead Institution: University of Wyoming
Principal Investigator: Mengqiang Zhu
Soil organic matter (SOM) is the largest organic carbon (C) pool in terrestrial ecosystems and its formation and stability strongly affect global carbon cycling and climate change. The widely accepted Microbial Efficiency-Matrix Stabilization (MEMS...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Sayandev Chatterjee
Toxic per- and polyfluoroalkyl substances (PFAS) are known to be released into the environment from a number of anthropogenic sources. Because of their high chemical resistance and thermal stabilities, these molecules are routinely used in...
Lead Institution: Oregon State University
Principal Investigator: Kate Lajtha
Limited knowledge of the molecular mechanisms behind soil organic matter (SOM) stabilization and destabilization processes impedes improving models of earth systems and global carbon dynamics, as well as our ability to understand important linkages...
Lead Institution: Cornell University
Principal Investigator: Carmen Martinez
Soil organic matter (SOM) is the largest reservoir of carbon (C) and nutrients, especially nitrogen (N), in terrestrial ecosystems. SOM is found throughout soil profiles, with content typically decreasing from surface to bedrock. Current theory...
Lead Institution: Ohio University
Principal Investigator: Jared DeForest
Phosphorus (P) is an essential nutrient for life, but its role in mediating important biogeochemical cycles is often overlooked or misunderstood due to the emphasis on carbon (C) and nitrogen (N) cycling in terrestrial ecosystem science, especially...
Lead Institution: University of Vermont
Principal Investigator: Aimee Classen
Soil carbon (C) feedbacks to the atmosphere remain one of the greatest areas of uncertainty in future climate predictions, largely due to an inadequate representation of three key factors in ecosystem models -- soil organic matter (SOM) chemistry,...
Lead Institution: Environmental Molecular Sciences Laboratory
Principal Investigator: Kirsten Hofmockel
Soil organic matter (SOM) is the largest active carbon reservoir in the terrestrial environment and significantly influences soil fertility, water quality, global C cycling and associated feedbacks to Earth's climate system. It is increasingly...
Lead Institution: Harvard University
Principal Investigator: Jeffrey Marlow
Methane is a singularly important molecule in the context of the United States' energy and environmental priorities. It represents a substantial energy source and potential feedstock for biofuel production schemes and is a strong greenhouse gas...
Lead Institution: Indiana University - Bloomington
Principal Investigator: Jonathan Raff
The overall goal of this proposal is to investigate how plant-microbe-mineral interactions drive emissions of reactive nitrogen from soils. Fluxes of reactive nitrogen oxides [NOy = NO + NO2 + HONO] from soil are poorly studied due to their highly...
Lead Institution: University of Michigan
Principal Investigator: Kerri Pratt
Single-particle microscopy will be used to characterize the chemical composition of individual Arctic atmospheric particles collected during two Department of Energy Atmospheric Radiation Measurement (DOE ARM) field campaigns as part of PI Pratt...
