This award provides support for "A Workshop to Develop a Science and Implementation Plan For Projecting Future Sea-Level Rise from Land-Ice Loss" to be held in July 2010. The workshop will bring together up to 46 U.S. scientists (with six of the slots reserved for graduate students and post-doctoral researchers) from many different fields including modeling, glaciology, oceanography, geology, and atmospheric science. The three overarching goals of the workshop are to 1) provide an overview of the current scientific understanding of ice-sheet dynamics; 2) to discuss ways to improve our understanding and modeling of the dynamic response of ice sheets to climate change, specifically by identifying the major sources of the uncertainties in developing sea level predictions; and 3) to identify the critical observational and modeling strategies need to reduce the uncertainties. Intellectual Merit: We have ample evidence from satellite imagery that land ice is being lost at a faster than expected rate, and the NSF has several funded projects that are beginning to address the reasons why land ice losses are accelerating, but there has not been a concerted effort to bring together a broad interdisciplinary team to address what (and where) we should be focusing our research dollars on in the next five years to best understand the why (process) question. The proposed workshop will deliver to the land ice loss community, the NSF, and other interested agencies a document summarizing and prioritizing the research topics that need to be addressed to understand the processes driving accelerated land ice loss. Broader Impact: Land ice loss is now thought to contribute more than half of the current sea level rise, and projections show the contribution of land ice loss is only going to increase. With 145 million people living on land only one meter above sea level, we must improve our predictions of sea level rise. This is going to take a concerted interagency effort, and the workshop is one step towards defining the path we need to take.A draft workshop report will be completed within two months of the meeting, and the report will then be circulated to the community for comment, and discussed at several scientific meetings before being submitted as a final document intended to be broadly available. Approximately half of the participants will be invited, and half of the participants will be selected via a competitive process. Funds provided by the NSF will only be used to support US scientists. Inclusion of early career scientists and students in the presentation and discussion of a necessarily interdisciplinary, integrated, and truly cutting edge area of Antarctic science will be extremely valuable in training the next generation of Antarctic researchers.

该奖项为将于 2010 年 7 月举行的“制定科学和实施计划以预测未来海平面因陆地冰损失上升而举办的研讨会”提供支持。该研讨会将汇集多达 46 名美国科学家（其中 6 名是美国科学家）。为来自建模、冰川学、海洋学、地质学和大气科学等许多不同领域的研究生和博士后研究人员保留的名额。研讨会的三个总体目标是：1）概述当前对冰盖动力学的科学认识； 2）讨论如何提高我们对冰盖对气候变化的动态响应的理解和建模，特别是通过确定海平面预测中不确定性的主要来源； 3）确定减少不确定性所需的关键观测和建模策略。学术价值：我们从卫星图像中获得充足的证据，表明陆地冰消失的速度比预期的要快，国家科学基金会有几个资助的项目正在开始解决陆地冰消失加速的原因，但还没有一个解决方案。齐心协力，聚集一个广泛的跨学科团队来解决我们在未来五年内应该将研究资金集中在什么（以及在哪里），以最好地理解为什么（过程）问题。拟议的研讨会将向陆地冰损失社区、国家科学基金会和其他感兴趣的机构提供一份文件，总结和优先考虑需要解决的研究主题，以了解加速陆地冰损失的过程。更广泛的影响：现在认为陆地冰损失占当前海平面上升的一半以上，并且预测显示陆地冰损失的贡献只会增加。由于有 1.45 亿人生活在海拔仅一米的陆地上，我们必须改进对海平面上升的预测。 这需要跨机构的共同努力，而研讨会是确定我们需要采取的道路的一步。研讨会报告草稿将在会议后两个月内完成，然后该报告将分发给社区以供参考。评论，并在几次科学会议上进行讨论，然后作为最终文件提交以供广泛使用。大约一半的参与者将被邀请，一半的参与者将通过竞争过程选出。 NSF提供的资金将仅用于支持美国科学家。让早期职业科学家和学生参与对南极科学必要的跨学科、综合和真正前沿领域的介绍和讨论，对于培训下一代南极研究人员来说非常有价值。
