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 $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...
This three-year, $1.2 million Project Grant from the National Science Foundation Division of Earth Sciences aims to test the role of seasonality in abrupt climate change through reconstructing fluctuations of a late-glacial ice mass in eastern North America. Under the Geosciences program (CFDA 47.050), which supports basic research in atmospheric, earth, and ocean sciences, the University of Maine will collaborate with researchers to determine the signature of summer warming-driven ice retreat...
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 National Science Foundation (NSF) Polar Programs (CFDA 47.078) Project Grant award of $157,585 to Morgan State University will fund collaborative research to disentangle the effects of runoff and ocean terminus on the velocity variations of fast-flowing outlet glaciers. The research aims to identify the relative impacts of melt-driven and ocean-driven ice flow changes, which is essential for improving computer models used to forecast future ice loss from the Greenland Ice Sheet. The project...
The University of Montana was awarded a $1,199,063 project grant from the National Science Foundation Division of Polar Programs to conduct collaborative research on observing the transformation of the Greenland ice sheet firn layer. The grant was awarded on November 1, 2021 with a completion date of October 31, 2026. Under the NSF's Polar Programs, which aims to expand fundamental knowledge of polar regions through basic research best conducted in or related to the Arctic and Antarctic (CFDA...
This $325,213 Project Grant awarded by the National Science Foundation's (NSF) Division of Polar Programs (CFDA 47.078) to The Trustees of Columbia University in the City of New York will investigate the role of meltwater in governing the geophysical properties of deforming icy systems. The project aims to create new flow laws that explicitly incorporate the effects of meltwater on ice flow, which is a key factor in modeling glacial mass loss and sea level rise. The research will employ...
This Project Grant award from the National Science Foundation's (NSF) Computer and Information Science and Engineering (CISE) program (CFDA 47.070) provides $596,821 to the University of Washington to develop new mathematical models and simulation tools for studying the calving of icebergs from glaciers. The project aims to improve predictions of sea-level rise by advancing the understanding of glacier terminus evolution and iceberg calving, which is a critical but poorly modeled aspect of...
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...
This Project Grant award, provided by the National Science Foundation's (NSF) Polar Programs (CFDA 47.078), supports a scientific study to observe and measure the ice-ocean interface at a glacier in Greenland. The $160,021 award to Trustees of Tufts College will deploy advanced optical fiber instruments to measure acoustic and temperature data and better understand the effects of sub-glacial melt and discharge on glacial calving. The project aims to generate novel measurements using...
This Project Grant award from the National Science Foundation (NSF) Division of Polar Programs (CFDA 47.078) provides $623,881 to the University of Maine System (UMS) for the project "CAREER: IMPROVING ESTIMATES OF CHANGING FIRN MELTWATER STORAGE AND FLUX IN TEMPERATE GLACIER SYSTEMS." The goal is to quantify spatial and temporal variations in firn thickness, density, porosity, water content, and volume change across the Juneau Icefield in Southeast Alaska and Northwest Canada. This research will characterize meltwater storage and movement in firn on hourly-to-yearly and cm-to-km scales to improve understanding of the impacts of firn volume change on meltwater flux and downstream ecosystems. As part of the project, UMS will build an interactive educational video game for use in classrooms and a glacier visitor center, train over 500 students to use the game and contribute to its development, and support an annual culture camp with indigenous communities to collaboratively address environmental changes in the region.
