Researchers from the Antarctic cryosphere and geosphere communities interested in using the RAID technology met for the 2nd RAID Science Planning Workshop, held in Herndon, Virginia from September 25-27, 2024. Goals of the workshop were to re-imagine how RAID can best be used to advance existing scientific questions and update the associated science planning needs for future drilling. The workshop brought together a multi-disciplinary group of scientists interested in using RAID, thereby growing participation of early-career polar researchers, promoting interdisciplinary research activities, and stimulating new cross-disciplinary research and proposal collaborations. A principal outcome of the workshop was development of a long-range science plan, embodied herein, that can provide scientific direction for future research that a platform like RAID can address. We identify critical science questions in four ice-sheet domains: (1) glaciology, glacial bed and sediment interface; (2) ice-core science and paleo-atmospheric records; (3) subglacial sampling, landscape history and bedrock evolution; and (4) borehole access and instrumentation. Potential drilling targets in East Antarctica are identified based on these science questions, principally in the corridor between South Pole and Dome A, the Wilkes Subglacial Basin, and the Aurora Highlands. To fully realize RAID\u2019s potential, a Heavy Science Traverse capability and resources to enable a high-altitude test season are crucial for demonstrating its capability on the Polar Plateau and establishing RAID as a long-term, interdisciplinary research facility.

The intellectual merit of this work is that the fabric and impurity content of the ice contain details on climate, volcanic activity and ice flow history. Such fabric measurements are currently taken by slicing an ice core into sections after it has started to depressurize which is an extremely time-intensive process that damages the core and does not always preserve the properties of ice in its in-situ state. In addition the ice core usually must be consumed in order to measure the components of the dust. The fabric measurements of this study utilize the concept that singly-scattered light in ice preserves most of its polarization when it is backscattered once from bubbles or dust; therefore, changes to the polarization of singly-backscattered light must originate with the birefringence. Measurements based on this concept will enable this program to obtain continuous records of fabric and correlate them to chronology and dust content. The project will also develop advanced borehole instruments to replace current logging tools, which require optical sources, detectors and power cables to be submerged in borehole fluid and lowered into the ice sheet at temperatures of -50oC. The use of telecommunications fiber will allow all sources and detectors to remain at the surface and enable low-noise signal processing techniques such as lock-in amplification that increase signal integrity and reduce needed power. Further, fiber logging systems would be much smaller and more flexible than current tools and capable of navigating most boreholes without a heavy winch. In order to assess fabric in situ and test fiber-optic borehole tools, field measurements will be made at WAIS Divide and a deep log will also be made at Siple Dome, both in West Antarctica. If successful, the broader impacts of the proposed research would include the development of new analytical methods and lightweight logging tools for ice drilling research that can operate in boreholes drilled in ice. Eventually the work could result in the development of better prehistoric records of glacier flow, atmospheric particulates, precipitation, and climate forcing. The project encompasses a broad base of theoretical, experimental, and design work, which makes it ideal for training graduate students and advanced undergraduates. Collaboration with schools and classroom teachers will help bring aspects of optics, climate, and polar science to an existing Middle School curriculum.", "east": -111.82, "geometry": ["POINT(-130.315 -80.535)"], "keywords": "Antarctica; Ash Layer; Borehole Camera; Glaciology; Ice Core Records; WAIS Divide; WAIS Divide Ice Core", "locations": "Antarctica; WAIS Divide", "north": -79.42, "nsf_funding_programs": null, "persons": "Talghader, Joseph", "project_titles": "Optical Fabric and Fiber Logging of Glacial Ice", "projects": [{"proj_uid": "p0000339", "repository": "USAP-DC", "title": "Optical Fabric and Fiber Logging of Glacial Ice"}], "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": -81.65, "title": "Optical Fabric and Fiber Logging of Glacial Ice (1142010)", "uid": "600172", "west": -148.81}]
