Lead Institution: University of Georgia
Principal Investigator: Rebecca Abney
Prescribed burning has exponentially increased in the United States over the past five years due to growing research into its use for land management and recent changes in legislation. While the impacts of wildfire on soil organic matter (SOM)...
Lead Institution: University of Washington
Principal Investigator: Alexander Gagnon
The pace of skeletal growth in shells and bones during biomineralization is impacted by interactions between biologically produced organic compounds and the growing mineral. The organic component within biominerals is small, typically less than 5 %...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Fan Mei
The vertical distribution of aerosol strongly influences the radiative forcing of the aerosols. However, observational data is limited. Both satellite observation and ground-based measurements are not able to provide well-resolved vertical profiles...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Xiao-Ying Yu
We will use in situ chemical imaging enabled by the microfluidic reactor SALVI to study a NAVY bilgewater emulsion model. Our main objective is to understand the evolving oil-water liquid-liquid interface. Such fundamental understanding is...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Sebastien Kerisit
The presence of mineral surfaces and of microorganisms significantly impacts the nature and composition of mineral phases formed in biogeochemical systems. Despite the importance of these heterogeneous reactions, predictions of the fate of...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Kevin Rosso
Understanding aquatic chemistry, the natural cycling and fractionation of elements, and energy flow in soils almost always involves, by necessity, attention to the governing influence of electron transfer processes. Interaction of aqueous Fe(II)...
Lead Institution: University of Miami
Principal Investigator: Cassandra Gaston
Aerosols transported from Africa are thought to critically impact the biogeochemical cycling of iron (Fe) and phosphorus (P) in the Amazon and relieve nutrient limitations in this ecosystem. Spectroscopy and microscopy will be used to compare the Fe...
Lead Institution: Clemson University
Principal Investigator: Vidya Appukuttan Suseela
Fine roots of Plants represent a major contributor to soil organic carbon storage. Despite its fundamental role in global carbon cycling, we know little about the factors controlling the residence time of carbon in fine roots. Although leaf litter...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Joseph Ryan
This research is part of an international collaborative effort to address the wide diversity of environmental roles that radionuclides can play during their lifetime within corroding nuclear wastes and their transport through a geologic repository...
Lead Institution: University of Washington
Principal Investigator: Alexander Gagnon
The pace of skeletal growth in shells and bones is impacted by interactions between biologically produced organic compounds and the growing mineral. The organic component within biominerals is small, typically less than 5 % by mass, but crucial. It...
