Non-technical AbstractThe Antarctic ice sheets are a critical element of Earth’s climate system and are undergoing rapid but poorly quantified change. The East Antarctic Ice Sheet is the largest repository of fresh water on the planet and represents the greatest potential contribution to sea-level rise, yet little is known about its thermal and mechanical conditions, as well as its potential for ice-mass loss. It also contains the oldest atmospheric climate records on the planet (trapped as bubbles of ancient air in ice); exploration for and use of those records is key to reliable modeling of potential climate variations in the near- and mid-term future. Much has been learned over the past decades from satellite observation, but we need direct observation within the East Antarctic Ice Sheet to validate and understand the state of change. To address these problems, the US Rapid Access Ice Drill was developed as a new drilling technology capable of quickly penetrating to the glacial bed of Antarctic ice sheets, retrieving ice core and rock core samples, and providing boreholes for down-hole logging of physical properties in ice. It has been tested in the field in Antarctica and is now ready for scientific research. The Principal Investigators of this award will convene a workshop to bring together research scientists with relevant experience to guide how, when and where the Rapid Access Ice Drill will be used for exploration for the oldest ice, to validate airborne radar imaging of glacial layers, to observe the conditions at the base of the ice sheet, and to recover cores of subglacial rock samples for laboratory analysis. The workshop will emphasize participation by early-career researchers who represent the next generation of polar scientists to engage in Antarctic research at the critical boundary separating the ice sheet from the solid earth below.Technical AbstractThe Antarctic ice sheets are a critical element of Earth’s climate system and are undergoing rapid but poorly quantified change. The East Antarctic Ice Sheet is the largest repository of fresh water on the planet and represents the greatest potential contribution to sea-level rise, yet little is known about its thermal and mechanical conditions, as well as its potential for ice-mass loss. It also contains the oldest meteoric and atmospheric gas climate records on the planet; exploration for and utilization of those records is key to reliable modeling of climate variations in the near- and mid-term future. Exploration of the interior of the East Antarctic ice sheet has proceeded slowly but steadily over several decades, mainly through remote sensing technologies. Despite great progress, pressing questions remain about Earth's climate 1 m.y. ago, ice deformation, geothermal heat flow, basal material properties, and subglacial geology. These problems are best addressed by quickly penetrating to the glacial bed of Antarctic ice sheets, retrieving ice core and rock core samples, and providing boreholes for down-hole logging of physical properties in ice. This is made possible by the US Rapid Access Ice Drill, developed as a new drilling technology capable of direct access. It has been tested in the field in Antarctica and is now ready for scientific research. The Principal Investigators of this award will convene a workshop in 2024 to support research community use of the Rapid Access Ice Drill in Antarctica. Workshop participants will meet to consider how the drilling system can best be used to advance our understanding of current operative ice-sheet processes, past climate records, history of ice-sheet development, and the geological substrate to the East Antarctic ice sheet, all of which have societal relevance. Research scientists with relevant experience will meet to guide how, when and where the Rapid Access Ice Drill will be used for exploration for the oldest ice, to validate airborne radar imaging of glacial layers, to observe the conditions at the base of the ice sheet, and to recover cores of subglacial rock samples for laboratory analysis. The workshop will emphasize participation by early-career researchers who represent the next generation of polar scientists to engage in Antarctic research at the critical cryosphere-geosphere boundary.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

非技术摘要南极冰盖是地球气候系统的关键要素，并且正在经历快速但量化不佳的变化。南极冰盖是地球上淡水的最大仓库，代表了对海平面上升的最大贡献，但对其热和机械状况以及冰质量损失的潜力知之甚少。它还包含地球上最古老的大气登山者记录（被困在冰上的古代气泡中）；这些记录的探索和使用是对近期和中期未来潜在气候变化的可靠建模的关键。在过去的几十年中，从卫星观察中学到了很多东西，但是我们需要在东南极冰盖内进行直接观察，以验​​证和了解变化的状态。为了解决这些问题，美国快速进入冰钻是一种新的钻井技术，能够快速渗透到南极冰盖的冰川床，取回冰芯和岩石核心样品，并提供钻孔，以便在冰中进行物理特性的底部记录。它已在南极洲的田间进行了测试，现在已经准备好进行科学研究。该奖项的主要研究人员将召集一个研讨会，将研究科学家汇集在一起​​，以指导如何，何时及地使用快速进入冰钻，用于探索最古老的冰，以验证冰川层的空中雷达雷达成像，以观察冰盖的条件，并在冰盖的基础上恢复岩石岩石岩石样品的核心。研讨会将强调早期研究人员的参与，他们代表下一代极地科学家在关键边界进行南极研究，将冰盖与下面的固体地球分开。技术摘要南极冰盖是地球气候系统的关键要素，并且经历了快速但量化量很差的变化。南极冰盖是地球上淡水的最大仓库，代表了对海平面上升的最大贡献，但对其热和机械状况以及冰质量损失的潜力知之甚少。它还包含地球上最古老的气候气候记录；这些记录的探索和利用是近期和中期未来气候变化的可靠建模的关键。几十年来，对南极冰盖内部的内部探索已经缓慢而安静地进行，主要是通过遥远的技术。尽管取得了巨大进展，但关于地球气候1 M.Y.的紧迫问题仍然存在。 AGO，冰变形，地热热流，基本材料特性和冰川地质。最好通过快速渗透到南极冰盖的冰川床，检索冰芯和岩石芯样品，并提供钻孔以下降冰的物理特性，从而解决这些问题。美国快速访问冰钻使这成为可能，这是一种能够直接访问的新钻探技术。它已在南极洲的田间进行了测试，现在已经准备好进行科学研究。该奖项的主要调查人员将在2024年召开研讨会，以支持南极快速访问冰钻的研究社区的使用。研讨会的参与者将开会以考虑如何最好地使用钻井系统来促进我们对当前的冰片过程，过去的气候记录，冰盖开发历史以及对东南极冰盖的地质基材的理解，所有这些都具有社会相关性。具有相关经验的研究科学家将符合指导如何，何时何地使用快速进入冰钻，以探索最古老的冰，以验证冰川层的空中雷达成像，以观察冰盖底部的条件，并恢复冰层岩石样品的核心，以进行实验室分析。该研讨会将强调早期职业研究人员的参与，他们代表下一代极地科学家在关键的Cryosphere-Geosphere边界上从事南极研究。这项奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来通过评估来诚实地通过评估来诚实地支持。
