A Workshop to Develop a Science and Implementation Plan For Projecting Future Sea-Level Rise from Land-Ice Loss

该奖项为将于2010年7月举行的“为预测未来海平面因陆地冰损失而上升制定科学和实施计划的研讨会”提供支持。 该研讨会将汇集多达46名来自不同领域的美国科学家（其中6名为研究生和博士后研究人员），包括建模，冰川学，海洋学，地质学和大气科学。研讨会的三个主要目标是：1）提供当前对冰盖动力学的科学认识的概述; 2）讨论如何提高我们对冰盖对气候变化的动态响应的认识和建模，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模拟策略。智力优势：我们从卫星图像中有充分的证据表明，陆地冰正在以比预期更快的速度消失，美国国家科学基金会有几个资助的项目开始解决陆地冰消失加速的原因，但还没有一个协调一致的努力，汇集了一个广泛的跨学科团队，以解决什么在未来五年里，我们应该把研究资金集中在哪里，以最好地理解为什么（过程）的问题。拟议的研讨会将向陆地冰损失社区，NSF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课题，以了解加速陆地冰损失的过程。更广泛的影响：现在认为，陆地冰损失造成了目前海平面上升的一半以上，预测显示，陆地冰损失的贡献只会增加。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。 这将需要跨部门的共同努力，而研讨会是朝着确定我们需要采取的路径迈出的一步。研讨会报告草案将在会议后两个月内完成，然后报告将分发给社区征求意见，并在几次科学会议上进行讨论，然后作为最终文件提交，以便广泛提供。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被选中。 NSF提供的资金将仅用于支持美国科学家。让早期的职业科学家和学生参与介绍和讨论南极科学的一个必要的跨学科、综合和真正尖端的领域，对培训下一代南极研究人员将是极其宝贵的。

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.
