This project will help us better understand sea ice, which is a major component of our climate. Sea ice is composed of many individual pieces and this project will study how these ice pieces break and deform. The researchers aim to create a new sea ice model to accurately model the behavior of ice pieces and use it to explain observations. This project will not only enhance our scientific knowledge but also bring real-world data analysis and modeling techniques into classrooms, train new scientists, and provide valuable opportunities for students in oceanography by organizing educational summer programs. The project's outcomes will be shared with the broader scientific community to help them learn more about sea ice and the Earth’s climate.This project addresses the critical need to enhance our understanding and modeling of sea ice processes, which play a significant role in shaping our climate. Existing climate models, with their coarse resolution, oversimplify sea ice dynamics. However, when examined at smaller scales, sea ice reveals itself as a complex system of interacting ice pieces with varying sizes, thicknesses, and shapes. The primary objectives of this project are to refine the representation of small-scale sea ice processes and establish clear connections to large-scale sea ice dynamics. The study focuses on modeling the deformation and fractures of sea ice pieces through a synergistic combination of data analysis, advanced numerical modeling, and theory development. The research's innovative aspect lies in the creation of a fundamentally new sea ice model that explicitly captures the life cycle of individual sea ice pieces. Validation of the model will utilize satellite sea ice observations. This model will be used to explore how statistical characteristics of the sizes and thickness of ice pieces are influenced by their collision and deformation physics. This approach aims to discern the impact of small-scale processes, like collisions and fractures, on larger sea ice characteristics that are crucial for improving sea ice representation in climate models. This model will be publicly accessible to benefit the broader polar oceanography community. Beyond scientific advancements, the project has a significant educational component. It intends to integrate scientific data analysis and modeling techniques into graduate and undergraduate classrooms, offering a comprehensive graduate-level course on sea ice dynamics. The incorporation of contemporary research material into polar oceanography and climate dynamics classes further contributes to educational outreach. Additionally, the initiative includes an annual summer program, Data Science in Oceanography, designed to attract talented students to graduate programs in oceanography. This program aims to provide ocean education and research mentoring, particularly to students who might not otherwise have such opportunities. The project's broader impact extends to the training of new polar scientists, supporting a Ph.D. student and numerous summer undergraduate students engaged in research activities.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.

该项目将帮助我们更好地了解海冰，这是我们气候的主要组成部分。海冰由许多单独的作品组成，该项目将研究这些冰块如何破裂和变形。研究人员旨在创建一个新的海冰模型，以准确地对冰块的行为进行建模，并使用它来解释观察结果。该项目不仅可以增强我们的科学知识，而且还将将现实世界的数据分析和建模技术带入教室，培训新科学家，并通过组织教育夏季计划为海洋学的学生提供宝贵的机会。该项目的结果将与更广泛的科学界分享，以帮助他们更多地了解海冰和地球的气候。该项目解决了增强我们对海冰工艺的理解和建模的关键需求，这在塑造我们的气候方面起着重要作用。现有的攀岩模型，其粗分辨率过分简化了海冰动力学。然而，当在较小的尺度上检查时，海冰将自己显示为一个复杂的冰块，具有不同尺寸，厚度和形状的冰块。该项目的主要目标是完善小规模海冰工艺的代表，并与大型海冰动力学建立明确的联系。该研究重点是通过数据分析，高级数值建模和理论发展的协同组合来建模海冰碎片的变形和断裂。该研究在创建一种新的海冰模型的创新方面，该模型明确捕捉了单个海冰碎片的生命周期。该模型的验证将利用卫星海冰观测。该模型将用于探索冰块大小和厚度的统计特征如何受其碰撞和变形物理学的影响。这种方法旨在辨别小规模过程（如碰撞和裂缝）对更大的海冰特征的影响，这些特征对于改善气候模型中的海冰表示至关重要。该模型将可以公开访问以使更广泛的极地海洋学社区受益。除了科学进步之外，该项目还具有重要的教育成分。它打算将科学数据分析和建模技术整合到研究生和本科教室中，并提供有关海冰动力学的全面研究生课程。当代研究材料在极地海洋学和气候动态课程中进一步有助于教育外展。此外，该计划包括一年的夏季计划，《海洋学数据科学》，旨在吸引才华横溢的学生参加海洋学研究生课程。该计划旨在提供海洋教育和研究心理，特别是对于可能没有这种机会的学生。该项目的更广泛影响扩展到对新的极地科学家的培训，并支持博士学位。该奖项反映了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标准来反映了NSF的法定任务。
