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...
The National Science Foundation awarded a $495,219 Project Grant under the Geosciences program (CFDA 47.050) to the University of Alaska Southeast (UAS) to develop and apply computer models to assess glacier outburst flood hazards across northwest North America. The key focus is on studying the Ɂakʷ Tʻoʻwak Glacier (Mendenhall Glacier) in Juneau, Alaska, which poses an annual flood risk to the local community. The research will use field and remote sensing data to inform physically-based...
The University of Alaska Southeast received a $566,927 project grant award from the National Science Foundation Division of Polar Programs on July 15, 2021 for research titled "Collaborative Research: Glacier-Sediment Interactions During Onset of Tidewater Glacier Retreat." Under the award, the University will conduct research through June 30, 2025 to strengthen understanding of polar regions, as outlined in the National Science Foundation's Polar Programs (CFDA 47.078) grantmaking...
This $346,823 Project Grant award from the National Science Foundation (NSF) Division of Polar Programs, CFDA 47.078, supports research to advance understanding of meltwater flow through glacial firn on the Juneau Icefield in Alaska. The research team at the University of Colorado will: (1) measure changes in surface melt and firn properties critical to firn hydrology, and (2) apply novel water-isotope stratigraphy techniques to determine timing and variability of meltwater infiltration. This...
This $155,602 project grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), will fund research to improve understanding of outlet glacier dynamics in Greenland. The University of Alaska Southeast will collaborate with other researchers to analyze new field observations and satellite data on runoff-driven and terminus-driven velocity variations at a large marine-terminating outlet glacier. Multivariate statistical...
The National Science Foundation (NSF) awarded a $505,558 project grant under the Polar Programs (CFDA 47.078) to Oregon State University. The 3-year grant, which began on October 1, 2023, will support a collaborative research project to elucidate the ocean dynamics governing melt at glaciers using Lagrangian floats. The research aims to determine the physical processes causing melting at an Alaskan glacier that ends in a fjord, focusing on whether recirculating cells and waves below the...
The National Science Foundation's Polar Research (CFDA 47.078) program awarded the University of Washington a $327,580 project grant to elucidate the ocean dynamics governing melt at glaciers using Lagrangian floats. The 3-year grant, awarded on October 1, 2023, will develop instruments that drift in three dimensions to study the physical processes causing melting at an Alaskan glacier ending in a fjord. The project aims to determine whether recirculating cells and waves below the sea surface...
This $372,154 Project Grant awarded by the National Science Foundation's Biological Sciences program (CFDA 47.074) supports collaborative research on the bioavailability of organic matter released from retreating glaciers. The research, conducted by Florida State University, aims to investigate the sources and cycling of this glacial organic matter and its implications for downstream aquatic ecosystems and global carbon cycling. Key activities include using advanced analytical techniques such as...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $312,259 to the University of Alaska Fairbanks (UAF) to conduct collaborative research on the last interglacial period approximately 130,000 to 115,000 years ago, when temperatures were naturally warmer than today. The project aims to better understand when and how much the Greenland and Antarctic ice sheets melted during this period, as well as the climate conditions and ice dynamical...
This four-year, $565,121 project grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), will fund collaborative research at the University of Alaska Fairbanks to improve understanding of outlet glacier dynamics in Greenland. The researchers will combine new field observations at a large marine-terminating outlet glacier with satellite data analysis and numerical modeling to disentangle the relative influence of...
