The intellectual merit of this project is embodied in the four closely linked leadership goals of this project which include: 1) producing and maintaining long-term and short-term integrated science and drilling technology plans in collaboration with the U.S. and international ice coring and drilling research communities, 2) providing field support with drilling equipment and expertise to support NSF-funded science, 3) identifying new technology needs and seeking funding for technology development and acquisition, and 4) enhancing communication and information exchange related to ice coring and drilling science and technology within the US and international ice science community. These goals relate to the importance of evidence from the polar ice sheets from ice cores, subglacial bedrock cores, and boreholes to access the subglacial aqueous environment, which has led to many important discoveries that have revolutionized climate science. These discoveries have also had important impacts on policy and thus also have societal relevance. Continued U.S. scientific leadership in this area depends critically not only on the support of scientists doing this research but also on the continued support of a dedicated facility to provide the field drilling support and accomplish engineering and technology development activities. This program and its education and public outreach activities will help to launch graduate students into promising careers, and the resulting scientific discoveries will benefit all citizens. Achieving the goals of this project will enable the U.S. ice science research community to realize implementation of their national and internationally-coordinated scientific goals, lead the world in ice science discoveries, nurture the education and development of the next generation of scientists and engineers, and help to communicate the importance of the discoveries to all.

Glacier ice can infiltrate several meters into these sediments, depending on the temperature and water pressure at the base of the glacier. To understand how ice infiltration into subglacial sediments affects glacier slip, the team will conduct laboratory experiments under relevant temperature and pressure conditions and compare the results to state-of-the-art mathematical models. Through an undergraduate research exchange between University of Wisconsin-Madison, Dartmouth College, and the College of Menominee Nation, Native American students will work on laboratory experiments in one summer and mathematical theory in the following summer. Ice-sediment interactions are a central component of ice-sheet and landform-development models. Limited process understanding poses a key uncertainty for ice-sheet models that are used to forecast sea-level rise. This uncertainty underscores the importance of developing experimentally validated, theoretically robust descriptions of processes at the ice-sediment interface. To achieve this, the team aims to build on long-established theoretical, experimental, and field investigations that have elucidated the central role of premelting and surface-energy effects in controlling the dynamics of frost heave in soils. Project members will theoretically describe and experimentally test the role of premelting at the basal ice-sediment interface. The experiments are designed to provide quantitative insight into the impact of ice infiltration into sediments on glacier sliding, erosion, and subglacial landform evolution.

These physical processes take place mainly on the Earth\u0027s dayside, diverting most of the energy along geomagnetic field lines toward both the northern and southern polar regions. Understanding this complex interaction process that couples both polar ionospheres is important for developing the physical models that can describe and predict space weather disturbances and help mitigate their impacts on humans\u0027 technological systems - from near-Earth space assets down to electrical grids and long pipelines. There is a strong need to collect sufficient geophysical data to investigate the above-mentioned processes, particularly from the southern hemisphere. With this award, the grantees will build and deploy additional ground-based observations platforms in the East Antarctic Plateau, enhancing capabilities of the existing meridional array of already deployed autonomous, low-powered magnetometers. This will make the southern array of magnetometers two-dimensional and geomagnetically conjugate to similar instruments deployed in Greenland and Svalbard, thus making possible a global view of the magnetospheric regions where natural, ultra-low frequency electromagnetic waves are generated. The project involves young scientists who will operate remote Antarctic magnetometers and analyze collected data to investigate space weather events and validate models. This project expands the Virginia Tech\u0027s partnership with the University of New Hampshire, New Jersey Institute of Technology, Polar Research Institute of China, and Technical University of Denmark.

Carefully controlled laboratory studies will be conducted at a variety of temperatures to empirically measure the mass transfer coefficient (the rate at which water moves from the solid to the vapor phase) for sublimating snow and to determine the time scale for isotopic equilibration between water vapor and ice. In addition the isotopic fractionation coefficient for vapor derived from sublimating ice will be determined and the results will be used to update existing models of mass transfer and isotopic evolution in firn. It is well known that water vapor moves through firn due to diffusion, free convection and forced convection. Although vapor movement through variably-saturated firn due to these processes has been modeled, because of a lack of laboratory data the mass transfer coefficient had to be estimated. Field studies have documented the magnitudes of post-depositional changes, but field studies do not permit rigorous analysis of the relative importance of the many processes which are likely to act in natural snow packs. The results of these laboratory investigations will be broadly applicable to a number of studies and will allow for improvement of existing physically-based models of post-depositional isotopic change, isotopic diffusion in firn, and vapor motion in firn. A major component of this project will be the design and fabrication of the necessary, novel experimental apparatus, which will be facilitated by existing technical expertise, cold room facilities, and laboratory equipment at CRREL. This project is a necessary step toward a quantitative understanding of the isotopic effects of water vapor movement in firn. The proposed work has broader impacts in several different areas. The modeling results will be applicable to a wide range of studies of water in the polar environment, including studies of wind-blown or drifting snow. The proposed collaborative study will partially support a Dartmouth graduate student for three years. This project will also provide support for a young first-time NSF investigator at the University of Vermont. Undergraduate students from Dartmouth will be involved in the research through the Women in Science Project and undergraduate students at the University of Vermont will be supported through the Research Experiences for Undergraduates program. The principal investigators and graduate student will continue their tradition of k-12 school outreach by giving science lessons and talks in local schools each year.
