Collaborative Research: A Field Campaign to Promote integration Between the Sea Ice Observational and Modeling Communities

如今，阿拉斯加北部海岸已经感受到海冰变化的影响，包括在阿拉斯加的巴罗，那里的许多当地居民的日常生活都围绕着海冰及其状况。这笔拨款将在巴罗开设一门课程，将模拟海冰的研究人员与实地研究海冰的研究人员聚集在一起。它将培养处于职业生涯不同阶段的研究人员，以建立跨学科的团队。课程的参与者将获得海冰观测和模型的加速课程，并与同事会面，以开展未来的跨学科合作活动。本课程将通过整合观测和建模工作来指导未来的海冰研究。该小组还将制定一份白皮书，说明北极系统科学与海冰有关的未来优先事项和活动；并在一次主要会议上举行一次会议，重点是在海冰观测和建模社区之间建立桥梁。该小组还将与当地的巴罗社区进行外展活动，包括社区对模型、预测能力和海冰未来前景的介绍。巴罗还为科学家们提供了一个绝佳的机会，让他们倾听和学习当地居民的意见，他们对海冰、正在发生的变化以及这些变化的影响有着深刻的了解。北极已经发生了巨大的变化，数值模型预测这种变化在可预见的未来还会继续。也许最显著的变化是海冰覆盖面积的减少，以及本世纪可能出现无冰的夏季。如果我们要预测和规划未来，了解海冰消失背后的机制及其对更大范围的北极和全球系统的影响至关重要。在这一领域取得进展的一个障碍是观测界和建模界之间的脱节。虽然有一个强大的研究小组观察北极海冰，另一个强大的研究小组对其进行建模，但这两个小组在很大程度上仍然是不同的。这笔拨款将用于资助一个为期一周的实地课程，介绍阿拉斯加巴罗的海冰观测和模型。巴罗可以很容易地到达各种海冰条件，有良好的后勤保障，而且是一个受北极海冰变化影响的社区。该课程将包括建模者和观察者，吸引来自不同职业阶段的研究人员。每天都有对近海海冰的实地观察，以及在大型模型中处理海冰的介绍和实践课程，提供运行模型和分析模型输出的实践经验。会议将讨论遥感工具和产品。额外的时间将用于讨论海冰研究的未来方向，以及如何更好地将模拟和观测结合起来。这是一个巨大的机会，可以提高我们观察和理解北极海冰覆盖正在发生的变化的能力，并通过观测和模型之间的更深层次的联系来预测未来的变化。这里提出的课程将弥补海冰研究界的一些知识空白。观测者将在大尺度模型中获得关于海冰处理问题的新见解，提高他们制定观测策略和网络的能力。建模者将对海冰的异质性复杂性及其对耦合相互作用的重要性有新的认识。这将产生更明智的方法来解决理解北极变化的问题，并改进研究海冰及其在北极系统中的作用的综合和综合方法。

The impacts of changing sea ice are being felt today on the shores of northern Alaska, including in Barrow, Alaska, where much of the local residents' everyday lives revolve around sea ice and its conditions. This grant will hold a course in Barrow to bring together researchers who model sea ice with those who study it in the field. It will entrain researchers at different stages of their careers, in order to build interdisciplinary teams. Participants in the course will receive an accelerated program on sea ice observations and models and meet colleagues for future collaborative interdisciplinary activities. The course will help direct future sea ice research by integrating observational and modeling efforts. The group will also develop a white paper on future priorities and activities in arctic system science as it relates to sea ice; and hold a session at a major meeting focused on building bridges between the sea ice observing and modeling communities.The team will also engage with the local Barrow community in outreach activities that will include community presentations on models, predictive capabilities, and the future outlook for sea ice. Barrow also provides an excellent opportunity for the scientists to listen and learn from local residents who have a tremendous understanding of sea ice, of the ongoing changes, and of the impact of those changes.The Arctic has undergone dramatic change and numerical models project this to continue for the foreseeable future. Perhaps the most striking change is the decline in sea ice cover and the possibility of ice-free summers within this century. Understanding the mechanisms behind sea ice loss and its consequences for the larger Arctic and global systems is of critical importance if we are to anticipate and plan for the future. One impediment to progress in this area is a disconnect between the observational and modeling communities. While there is a strong group of researchers observing arctic sea ice and another strong group modeling it, these two groups have remained largely distinct. This grant will support a field course for a one-week introduction to sea ice observations and models based in Barrow, Alaska. Barrow affords easy access to a range of sea ice conditions, excellent logistics, and is a community impacted by the changes in arctic sea ice. The course will include a mix of modelers and observers, drawing researchers from different career stages. Each day there will be field observations on the shorefast sea ice, as well as presentations about the treatment of sea ice in large-scale models and practical sessions to provide hands-on experience with running models and analyzing model output. There will be discussions of remote sensing tools and products. Additional time will be targeted for discussions about future directions of sea ice research and how to better integrate modeling and observations.There is a tremendous opportunity to improve our ability to observe and understand the ongoing changes in the arctic sea ice cover, and to project future changes through a deeper connection between observations and models. The course proposed here will remedy some of the knowledge gaps within the sea ice research community. Observers will gain new insight on the issues regarding the treatment of sea ice in large-scale models, improving their ability to formulate observation strategies and networks. Modelers will gain new appreciation for the heterogeneous complexity of sea ice and its importance for coupled interactions. This will result in better-informed methods to address questions of understanding arctic change and improved integration and synthetic approaches to studying sea ice and its role in the arctic system.
