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...
The National Science Foundation (NSF) awarded the University of California, Davis a $605,073 Project Grant under the Polar Programs (CFDA 47.078) federal grant program to conduct research on the effects of environmental change on microbial self-organized patterns in Antarctic lakes. The 3-year project, running from March 2024 to February 2027, will advance understanding of the spatial structure and relationships of benthic microbial communities in Lake Vanda, Antarctica, and how they respond...
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...
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...
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 Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), provides $175,853 to support research examining mixotrophic grazing as a strategy for Antarctic plankton to meet nutritional requirements under iron and manganese deficiency conditions. The award to the Virginia Institute of Marine Science will fund one graduate student, two undergraduate summer interns, and two early career scientists to conduct...
The National Science Foundation awarded a three-year, $338,836 Project Grant to the University of Colorado Boulder under the Polar Programs federal grant program (CFDA 47.078). The grant will support collaborative research titled "Moving Beyond the Margins: Modeling Water Availability and Habitable Terrestrial Ecosystems in the Polar Desert of the McMurdo Dry Valleys." The research aims to strengthen fundamental understanding of the polar regions through expanding knowledge of water...
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...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) is for a collaborative research project that aims to constrain virus loss and investigate the flow of carbon and nitrogen through virovory, or the direct transfer of nutrients and energy up the food web through grazing on virus particles, in temperate marine ecosystems. The $1,153,105 award to the University of Maryland Center for Environmental Science will fund laboratory incubations and...
The National Science Foundation Division of Polar Programs awarded a $185,342 project grant to the University of Connecticut Office of Sponsored Programs to support research exploring links between iron and phosphorus nutrition of Antarctic marine phytoplankton. The award, made under the Polar Programs federal grant program (CFDA #47.078), will fund research from January 15, 2022 through December 31, 2023. The Polar Programs program aims to expand fundamental polar region knowledge and...
