Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: James Stegen
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 and models will be developed across a broad range...
Lead Institution: Colorado State University
Principal Investigator: Daniela Cusack
The specific aim of this experiment is to assess the effects of soil moisture, fertility and fungal symbiont on root exudate activity for an abundant tropical tree species (Tabebuia rosea). The project tracks the production and movement of root...
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 recover, and this results in changes to the patterns of...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Kevin Rosso
We propose to conduct the photodegradation on two dissolved organic matter (DOM) samples in the presence of hematite nanoparticles under solar light for the first time. This treatment will produce reactive oxygen species to abiotically oxidize...
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: 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: Pacific Northwest National Laboratory
Principal Investigator: Vijayakumar Murugesan
The specific aim of this project is to probe the structure-property relationships of energy storage materials based on multivalent ions (Mg2+, Ca2+ and Al3+) under dynamic electrochemical cycling conditions with a range of spatial (down to atomic)...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: James Stegen
We are developing predictive understanding of the processes that govern influences of hydrologic exchange flows on water quality, nutrient dynamics, and ecosystem health in dynamic river corridor systems. Exchange of water between rivers and the...
Lead Institution: Lawrence Berkeley National Laboratory
Principal Investigator: Eoin Brodie
The pathways of carbon transport and loss through and from soils--soil organic matter (SOM) depolymerization to dissolved organic carbon and mineralization to carbon dioxide (CO2)--are fundamentally driven by microbial activity, which is strongly...
