Key activities include snow surveys, geophysical measurements, soil...
This $398,984 Project Grant award, provided by the National Science Foundation's Geosciences Program (CFDA 47.050), supports research to quantify the biophysical, physiological, and phenological impacts of increasing carbon dioxide (CO2) levels on vegetation and their effects on future climate change. The research utilizes the Community Earth System Model to examine the direct impacts of CO2 fertilization and stomatal closure, as well as the indirect effects of a longer growing season, on...
This $1.6 million Project Grant from the National Science Foundation Division of Environmental Biology was awarded on September 1, 2021 to Oregon State University with a completion date of August 31, 2025. The grant supports modeling of interactions between community forest dynamics, local livelihoods, and institutional changes under the Geosciences program (CFDA 47.050). The Geosciences program aims to expand fundamental earth science knowledge and understanding of the integrated Earth system...
This $249,742 Project Grant awarded by the National Science Foundation (NSF) Geosciences Program (CFDA 47.050) supports research by Portland State University to model the impacts of salt stress on coupled carbon and water dynamics in dryland critical zones. The key products and services to be delivered under this grant include: Conducting controlled greenhouse experiments and developing models to understand how factors like root/shoot water and salt storage, plant salt uptake, and...
This $270,754 Project Grant award from the National Science Foundation's (NSF) Biological Sciences program supports collaborative research to investigate the impacts of the ongoing megadrought in the American West on soil moisture, ecosystem carbon-water cycling, and remote sensing capabilities. The research team, led by the Trustees of Indiana University, will synthesize hundreds of long-term soil moisture measurements with remotely-sensed data and eddy covariance tower observations to...
Colorado State University was awarded a $199,724 Project Grant from the National Science Foundation under the Geosciences program (CFDA 47.050) for the period of July 1, 2021 through June 30, 2024. The grant will support collaborative research examining new roles for reactive oxygen species in mediating carbon fluxes at the terrestrial-aquatic interface. Specifically, the funding will enable investigation of how reactive oxygen species produced during microbial decomposition in soils and...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $305,824 to Oregon State University (OSU) to conduct collaborative research on how changes in land cover and climate are impacting grassland water and carbon cycles below-ground. The project will: 1) quantify how woody encroachment alters soil water flow and storage, 2) measure the impact on groundwater and stream hydrology, 3) quantify changes in subsurface carbon processes, and 4) model the impacts of climate changes on carbon sequestration as woody plants expand in grasslands. This interdisciplinary effort, running from September 2024 through August 2027, will train undergraduate/graduate students and a postdoctoral researcher to collect field data and develop numerical models to address these critical ecohydrological questions. The research aims to provide transferable knowledge on the impacts of climate and land cover disturbance in vulnerable grassland systems.
