- This Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), provides $210,495 to support research examining how microbial extremophiles in Antarctica respond to environmental changes in salinity. Led by researchers at the University of Tennessee, the grant will fund comparative analyses of gene expression patterns and secondary metabolite production in lab microcosm studies using microbial isolates previously...
- This Project Grant award from the National Science Foundation (NSF) Division of Polar Programs (CFDA 47.078) will fund research to constrain biomass mobilization within and out of Lake Fryxell in Antarctica's McMurdo Dry Valleys during a period of unprecedented ice thinning. The $159,765 award, effective September 1, 2023 through August 31, 2024, will support the University of New Mexico's efforts to 1) understand how changing regional climate and seasonal loss of lake ice cover will affect...
- The National Science Foundation Division of Polar Programs awarded a $137,045 Project Grant to the University of Tennessee under the Polar Programs federal grant program (CFDA 47.078) to conduct collaborative research investigating microbial degradation of complex organic matter in Antarctic benthic sediments from July 2022 to June 2025. The research aims to combine genomics methods with estimates of enzyme abundance and activity to determine rates of carbon degradation by microbes in...
- This $609,982 Project Grant from the National Science Foundation's (NSF) Polar Programs will support research into Antarctic marine nematodes and their host-associated microbiomes. Over a four-year period ending June 2026, the University of Georgia Research Foundation will conduct molecular analyses to better understand the biodiversity, evolution, and ecology of benthic meiofauna in Antarctic ecosystems. Researchers will use modern omics tools and classical taxonomy to determine if molecular...
- This National Science Foundation project grant award of $140,006 supports research into microbial degradation of complex organic matter in Antarctic benthic sediments. Funded under the Polar Programs federal grant program (CFDA 47.078), the award will allow Central Michigan University to investigate the role microbes play in degrading organic matter and releasing nutrients to the Southern Ocean. Over the two-year period from July 2022 to June 2025, the university will combine genomics methods...
- Grant Award Summary The Virginia Institute of Marine Science (VIMS) received a $362,817 Project Grant from the National Science Foundation's (NSF) Division of Polar Programs (CFDA 47.078) awarded July 1, 2025, with completion targeted for June 30, 2027. This collaborative research project focuses on decoding the microbiome diversity and potential function in the Antarctic pteropod Limacina rangii, a key planktonic species in the Southern Ocean food web. The primary products include genetic and...
- This $379,674 National Science Foundation Division of Polar Programs project grant will fund research into mixotrophic grazing strategies of Antarctic plankton as a means to meet nutritional needs in iron- and manganese-deficient conditions of the Southern Ocean. The University of Georgia Research Foundation, Inc. will conduct culture studies of microalgal isolates from the Southern Ocean to measure growth responses, consumption behavior, and cellular changes in iron and manganese limitation....
This two-year, $181,499 National Science Foundation Division of Polar Programs project grant will fund research into the role of nutrient limitation and viral interactions on microbial community assembly in Antarctic cryoconite holes. Cryoconite holes are sediment-filled melt holes in glacial surfaces that can support active microbial life in Antarctica's otherwise frozen landscape. The principal investigators at Arizona State University will conduct nutrient addition experiments using previously collected cryoconite sediments with varying viral and nutrient levels. This will test hypotheses about key limiting nutrients like phosphorus and how relaxing nutrient limitations impacts microbial and viral diversity, abundance, and infection dynamics. Results from these cryoconite microcosm studies could improve understanding of microbial-viral relationships under nutrient stress and inform forecasts of cryospheric environmental change impacts. By May 2024, the researchers aim to publish findings and share discoveries with K-12 and undergraduate students to advance the National Science Foundation's goal of expanding fundamental Antarctic science knowledge.
