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...
This $157,585 federal Project Grant awarded by the National Science Foundation's Polar Programs (CFDA 47.078) will support collaborative research to disentangle the impacts of runoff and ocean terminus dynamics on the flow velocities of fast-flowing outlet glaciers in Greenland. The primary awardee, Morgan State University, will combine new field observations and satellite data analysis to address three key research questions: 1) How does runoff affect outlet glacier flow over timescales from...
This $127,350 project grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), will support collaborative research to improve modeling of terminus ablation for Greenland's outlet glaciers. The researchers will use machine learning to analyze glaciological observations and better understand the variables influencing the ice-ocean boundary. They will develop an equation to represent ice-ocean interactions in an ice sheet...
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...
The National Science Foundation awarded a $269,223 Project Grant to the University of Texas at Austin from the Polar Programs federal grant program (CFDA 47.078) to support research titled "Collaborative Research: Machine-Enabled Modeling of Terminus Ablation for Greenland's Outlet Glaciers." The research aims to improve projections of sea-level rise from Greenland through developing physics-based modeling of ice-ocean interactions at outlet glaciers using machine learning analysis...
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...
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...
The National Science Foundation (NSF) Division of Polar Programs awarded a $133,492 Project Grant to the University of Florida (UF), through its Division of Sponsored Research, to conduct collaborative research on quantifying the effect of moraine building on the stability of Greenland tidewater glaciers. The project aims to collect observations from the fronts of three Greenland outlet glaciers to determine if the deposition of sediment at the ice-ocean boundary is responsible for the...
This Project Grant award of $208,083 from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) supports a collaborative research project to investigate the melting of tidewater glaciers and its impact on sea-level rise. The primary objective is to use specialized underwater robots and sensors to directly measure the velocity, salinity, and temperature of the turbulent boundary layer at a near-vertical glacier face and relate these to observations of the subsurface ice morphology....
