Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Fan Mei
We propose a combined experimental and modeling study to characterize the vertical profile of atmospheric aerosol collected via a tethered balloon system using multi-modal micro-spectroscopy techniques, advanced mass spectrometry platforms, and high...
Lead Institution: University of Florida
Principal Investigator: Hui-ling Liao
As the critical members of forest microbiome, ectomycorrhizal fungi (EMF) play important roles in forest ecosystems. EMF provide their tree hosts with macro- and micronutrients in exchange for photosynthetically fixed carbon (C) and can catalyze the...
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: 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: West Texas A&M University
Principal Investigator: Seong-gi Moon
Our current knowledge of aerosol-cloud interactions in the Arctic is inadequate for accurate modeling of northern high-latitude regions. To fill this gap, the field campaign was recently conducted in Ny-Alesund, Svalbard, during March 2-30, 2017 as...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Susannah Burrows
The atmospheric concentration of ice-nucleating particles (INPs) impacts the formation and development of cloud ice crystals, affecting cloud radiative properties and precipitation. However, predictive understanding of INP concentrations in the...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Kevin Rosso
Fe(III)-oxide nanominerals are ubiquitous primary sorbents of organic carbon, organic acid exudates, and toxic metals in terrestrial, aquatic, and subsurface ecosystems. In soil ecosystems, particularly in the rhizosphere, this co-association has...
Lead Institution: Purdue University
Principal Investigator: Alexander Laskin
Recent discovery of solid (glassy) atmospheric soil organic particles (ASOP), emitted through atmosphere-land-surface interactions in the area of Southern Great Plains (SGP) suggests that ASOP may have a regional-scale impact on the atmospheric...
Lead Institution: University of Illinois at Urbana-Champaign
Principal Investigator: Yi Lu
This proposal addresses a major under-explored area of research in our understanding of foundational principles for predictive biology central to energy production, i.e., the role of post-translational modifications in oxygen reduction reaction (ORR...
