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重要组成部分，正在经历快速但难以量化的变化。东南极冰盖是地球上最大的淡水储存库，是海平面上升的最大潜在贡献，但人们对其热力和机械条件以及冰块质量丧失的可能性知之甚少。它还包含地球上最古老的大气气候记录(被困在冰中的古代气泡中)；探索和使用这些记录是可靠地模拟近期和中期未来潜在气候变化的关键。在过去的几十年里，从卫星观测中学到了很多东西，但我们需要在东南极冰盖内进行直接观测，以验证和了解变化的状态。为了解决这些问题，美国快速进入冰钻作为一种新的钻探技术被开发出来，能够快速穿透到南极冰盖的冰床，提取冰芯和岩芯样本，并提供钻孔来记录冰中的物理性质。它已经在南极洲的野外进行了测试，现在准备进行科学研究。该奖项的首席调查人员将召集具有相关经验的研究科学家举办一次讲习班，指导如何、何时以及在哪里使用快速通道冰钻勘探最古老的冰，验证对冰川层的机载雷达成像，观察冰盖底部的条件，并回收冰川下岩石样品的岩芯用于实验室分析。研讨会将强调职业生涯早期的研究人员的参与，他们代表着下一代极地科学家，在将冰盖与下面的固体地球分开的临界边界上从事南极研究。技术摘要南极冰盖是地球气候系统的关键要素，正在经历快速但难以量化的变化。东南极冰盖是地球上最大的淡水储存库，是海平面上升的最大潜在贡献，但人们对其热力和机械条件以及冰块质量丧失的可能性知之甚少。它还包含地球上最古老的气象和大气气体气候记录；探索和利用这些记录是可靠地模拟近期和中期未来气候变化的关键。几十年来，对南极东部冰盖内部的勘探进展缓慢但稳定，主要是通过遥感技术。尽管取得了很大进展，但关于地球气候1英里的紧迫问题仍然存在。冰川变形、地热流动、基本物质性质和冰下地质。解决这些问题的最好办法是迅速渗透到南极冰盖的冰床，取回冰芯和岩芯样品，并提供钻孔，以便在井下记录冰的物理性质。这是由美国快速接入冰钻实现的，该钻探是作为一种能够直接进入的新钻井技术开发的。它已经在南极洲的野外进行了测试，现在准备进行科学研究。该奖项的首席调查人员将于2024年召开一次研讨会，以支持研究界在南极洲使用快速通道冰钻。讲习班与会者将开会审议如何最好地利用钻探系统来促进我们对当前有效的冰盖过程、过去的气候记录、冰盖发展的历史以及东南极冰盖的地质底物的了解，所有这些都具有社会意义。具有相关经验的研究科学家将开会指导如何、何时和在哪里使用快速通道冰钻勘探最古老的冰，验证机载雷达对冰川层的成像，观察冰盖底部的条件，并恢复冰川下岩石样品的岩心供实验室分析。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，在关键的冰冻圈-地圈边界从事南极研究。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
