Collaborative Research: IPY, The Next Generation: A Community Ice Sheet Model for Scientists and Educators, with Demonstration Experiments in the Amundsen Sea Embayment Region

Johnson/0632161该奖项支持一个创建“社区冰盖模型(CISM)”的项目。拟议活动的学术价值在于，这种模型的开发将有助于推动冰盖建模科学的发展。开发该模型的目的是确保该模型是准确的、健壮的、有充分记录的、直观的和计算高效的。开发过程将强调软件设计的原则。将作出两项相辅相成的努力。其中一项将涉及在南极洲阿蒙森海湾地区进行新的预测模拟实验，目的是了解基础过程和冰盖动力学之间的相互作用如何导致冰盖的突然重新配置，以及这些重新配置如何影响其他地球系统。新的模拟物理将包括高阶应力项，允许适当地分辨冰流和陆架特征，以及相关的数值方法，允许更高和更低阶物理共存于一个模型中。拟议活动的更广泛影响涉及教育和公众宣传。该模型将在用户界面和设计方面提升到高标准，这将允许为K-12教育制作以探究为基础的极地和气候科学课程。冰川学研究方法的发展本身将意味着冰川学研究方式的巨大变化，消除了极地研究取得进展的许多障碍，例如重复工作、出版缺乏透明度、缺乏可供他人联系和参考的冰冻圈模型以及开始调查的共同起点。随着适当的接口的开发，将制定在教育中使用信息和通信技术的课程。参与这项资助的学生将被要求通过包括地方和州科学博览会在内的各种机制参与公共宣传。该模型也将作为培养“新一代”气候科学家的基础。该项目与国际极地年(IPY)相关，因为研究小组是多机构和多学科的，将把新的群体和新的专业带入极地研究领域，是一个更大的提案小组的一部分，其研究重点是南极洲阿蒙森海湾计划地区的研究。该项目的范围是国际化的，软件开发的性质是相当国际化的，英国和比利时坚定地承诺合作。此外，还将设立一个国际外部咨询委员会，用于指导发展，并作为国际年其他活动的纽带。

Johnson/0632161This award supports a project to create a "Community Ice Sheet Model (CISM)". The intellectual merit of the proposed activity is that the development of such a model will aid in advancing the science of ice sheet modeling. The model will be developed with the goal of assuring that CISM is accurate, robust, well documented, intuitive, and computationally efficient. The development process will stress principles of software design. Two complementary efforts will occur. One will involve novel predictive modeling experiments on the Amundsen Sea Embayment region of Antarctica with the goal of understanding how interactions between basal processes and ice sheet dynamics can result in abrupt reconfigurations of ice-sheets, and how those reconfigurations impact other Earth systems. New modeling physics are to include the higher order stress terms that allow proper resolution of ice stream and shelf features, and the associated numerical methods that allow higher and lower order physics to be coexist in a single model. The broader impacts of the proposed activity involve education and public outreach. The model will be elevated to a high standard in terms of user interface and design, which will allow for the production of inquiry based, polar and climate science curriculum for K-12 education. The development of a CISM itself would represent a sea change in the way that glaciological research is conducted, eliminating numerous barriers to progress in polar research such as duplicated efforts, lack of transparency in publication, lack of a cryospheric model for others to link to and reference, and a common starting point from which to begin investigation. As the appropriate interfaces are developed, a curriculum to utilize CISM in education will be developed. Students participating in this grant will be required to be involved in public outreach through various mechanisms including local and state science fairs. The model will also serve as a basis for educating "a new generation" of climate scientists. This project is relevant to the International Polar Year (IPY) as the research team is multi-institutional and multi-disciplinary, will bring new groups and new specialties into the realm of polar research and is part of a larger group of proposals whose research focuses on research in the Amundsen Sea Embayment Plan region of Antarctica. The project is international in scope and the nature of software development is quite international, with firm commitments from the United Kingdom and Belgium to collaborate. In addition there will be an international external advisory board that will be used to guide development, and serve as a link to other IPY activities.
