This $244,394 Project Grant award from the National Science Foundation's Biological Sciences (CFDA 47.074) Federal Grant Program supports collaborative research by the University of Alaska Southeast (UAS) to investigate the bioavailability of dissolved organic matter (DOM) released from glaciers. The research aims to determine whether modern microbial production on glacier surfaces or ancient carbon sources are the primary drivers of the high bioavailability of glacier DOM, which can impact...
This $300,785 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project to characterize the chemical composition and bioavailability of dissolved organic matter released by marine nitrifying microorganisms. The project aims to determine how this material contributes to carbon cycling in the deep ocean, which may help improve biogeochemical models and inform potential marine carbon dioxide removal activities. The research will...
This $199,879 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds research at the University of Alaska Southeast to evaluate how changing glaciers influence the movement of freshwater, nutrients, and minerals from coastal watersheds in Southeast Alaska to nearshore waters in the Gulf of Alaska. Under the award, set to run from January 1, 2023 to December 31, 2024, project personnel will sample rivers with glaciers throughout the year and intensely...
Florida State University was awarded a three-year, $142,382 Project Grant from the National Science Foundation under the Geosciences program (CFDA 47.050). The grant will support collaborative research investigating the source and flux of dissolved organic carbon released from methane seeps to the deep ocean. As part of the Geosciences program's mission to expand fundamental knowledge of the integrated Earth system through basic research, this project will enhance understanding of carbon cycling...
This five-year, $565,180 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports collaborative research on the impacts of global changes on glacial fjords, ecosystems, and communities in Greenland. The awardee, Bigelow Laboratory For Ocean Sciences, will partner with Pinngortitaleriffik / Gronlands Naturinstitut to study glacial fjords, ecosystems, and local communities in Greenland through 2026. The Geosciences program aims to expand fundamental knowledge...
The National Science Foundation awarded a $374,918 Project Grant under the Geosciences program (CFDA 47.050) to The Regents of the University of Colorado to study the role of Icelandic fjords in the global carbon cycle. The project aims to quantify the amount of organic carbon stored in Icelandic fjord sediments and investigate how climate change may impact carbon sequestration in these systems. Key research activities include analyzing sediment cores using geochemical and lipid biomarker...
This National Science Foundation Project Grant award of $360,269 will fund research into the chromatographic separation and degradation of dissolved and particulate organic matter in permeable shelf sediments. The award was made on June 1, 2022 to Florida State University's Sponsored Research Administration under the Geosciences program (CFDA 47.050) and is scheduled to be completed by May 31, 2025. The research will study how sandy sediments influence the carbon cycle through their ability to...
The National Science Foundation (NSF) Division of Earth Sciences awarded a $750,000 Project Grant to the Regents of the University of Colorado (UC Boulder) to study the groundwater connection between melting glaciers and mountain streams under the NSF's Geosciences program (CFDA 47.050). The project will characterize two glaciated watersheds in Colorado and Montana, analyze relevant environmental data, and conduct numerical modeling to understand how glacier meltwater affects aquifer...
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 $401,056 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will fund research examining the effects of terrestrial organic matter inputs on coastal mercury cycling, methylmercury production and bioaccumulation in the Gulf of Maine. Specifically, the grantee will study how climate change-driven increases in rainfall and river runoff influence the delivery of contaminants, organic matter and nutrients from land to coastal waters. Field surveys and shipboard...
