Project Grant 2445119
- 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's (NSF) Polar Programs (CFDA 47.078) awarded a $589,325 Project Grant to the University of California, Santa Barbara (UCSB) to study the role of microbes in inhibiting the release of methane, a potent greenhouse gas, from Antarctic methane seeps. The 2-year research project, titled "CAREER: Ecosystem Impacts of Microbial Succession and Production at Antarctic Methane Seeps", aims to advance the fundamental understanding of which microbes consume...
- 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 National Science Foundation (NSF) Project Grant award for $425,311 to the Carnegie Institution for Science supports collaborative research on how winter conditions affect the ecological function of seasonally-frozen lakes. The multi-year project (11/1/2023 - 10/31/2027) will develop a comprehensive, predictive model of year-round lake ecosystem dynamics by: Conducting detailed seasonal studies of water quality, plankton populations, food webs, and organic matter cycling in 12 lakes with...
- 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...
- 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...
- Northern Arizona University received a $387,675 project grant award from the National Science Foundation on April 1, 2021 to conduct research titled "COLLABORATIVE RESEARCH: MOVING BEYOND THE MARGINS: MODELING WATER AVAILABILITY AND HABITABLE TERRESTRIAL ECOSYSTEMS IN THE POLAR DESERT OF THE MCMURDO DRY VALLEYS." The research is funded through the NSF's Polar Programs (CFDA 47.078) and aims to strengthen fundamental knowledge and understanding of polar regions by encouraging basic...
- This National Science Foundation Project Grant of $181,600 supports research into the role of nutrient limitation and viral interactions on microbial community assembly in Antarctic cryoconite holes. Funded under the NSF's Polar Programs (CFDA 47.078) to strengthen fundamental polar science, the award will allow the University of Colorado Boulder to conduct experimental nutrient addition studies using cryoconite sediments collected across a gradient of viral diversity and nutrient levels in...
This Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) provides $794,401 to the University of California, Davis to characterize seasonal changes in benthic microbial mats in Lake Fryxell, McMurdo Dry Valleys, Antarctica. The project aims to study how these photosynthetic mats respond to the transition from winter darkness to spring/summer sunlight. Researchers will install temporary shades to extend winter-like conditions into spring, allowing them to sample and analyze changes in mat community composition, cell activity, and water chemistry during this critical transition period. This research will enhance understanding of the unique microbial ecosystems in permanently ice-covered Antarctic lakes and how they adapt to extreme seasonal variability.
