Greenland ice loss quadrupled over the last two decades and presently accounts for one quarter of global sea level rise. The ice loss is due to changes in surface mass balance and ice sheet dynamics associated with rising air and ocean temperatures. The associated increasing freshwater discharge is impacting the regional ocean, including its ecosystems, and has the potential to impact the large-scale North Atlantic circulation. Thus, Greenland's changes are having far-reaching consequences for global societies, yet the mechanisms responsible for these changes are not well understood. Dynamic ice loss, in particular, was likely triggered by changes at the margins of marine-terminating glaciers, through ice/ocean/atmosphere processes that are either absent or poorly represented in climate, ice sheet and ocean models. The interaction of the ocean, the glaciers and atmosphere at Greenland?s margins is a new research frontier. The complex processes involved include the coupling of multiple components of the Earth system, the challenges of obtaining and integrating diverse data from this region, and of modeling such a complex system. These challenges make this a problem that can only be addressed by bringing together multiple disciplines, including data management, collaboratively exploring diverse approaches and working across national borders. This project establishes a network to help scientists working in this area to share their data and work collaboratively.The goal of this project is to substantially enhance multi-disciplinary activities and collaboration through the establishment of the GRISO (Greenland Ice Sheet Ocean) Science Network - an international, multidisciplinary, open network of scientists and cyberinfrastructure experts. Participants have a shared interested in advancing collective understanding of problems related to Greenland Ice Sheet change and its impact on regional and global climate. GRISO RCN activities will bring together scientists focused on all aspects of ice/ocean/atmosphere/climate data in Greenland and provide a framework for productive collaborative interaction. Specific objectives include two workshops, and a series of synthesis efforts. Additionally, a virtual data portal, leveraging existing infrastructure, will make interdisciplinary data submission and data availability easier and promote uniform and appropriate data management practices. The RCN builds on activities initiated by the former GRISO US CLIVAR Working Group and explicitly addresses priorities identified in a report from an international workshop held in 2013.

在过去的二十年中，格陵兰冰损失倍增了三倍，目前占全球海平面上升的四分之一。冰的损失是由于表面质量平衡的变化以及与空气和海洋温度升高有关的冰盖动态。相关的增加淡水排放量正在影响区域海洋，包括其生态系统，并有可能影响大型北大西洋循环。因此，格陵兰的变化对全球社会产生了深远的后果，但是对这些变化负责的机制却尚未得到充分理解。尤其是动态冰的损失可能是由于海洋终止冰川边缘的变化而引起的，这些变化是通过在气候，冰盖和海洋模型中不存在或不良代表的冰/海洋/大气过程。格陵兰岛边缘的海洋，冰川和气氛的相互作用是新的研究边界。所涉及的复杂过程包括地球系统多个组件的耦合，从该地区获取和整合多种数据的挑战以及对这种复杂系统进行建模的挑战。这些挑战使这一问题只能通过将多个学科汇总在一起，包括数据管理，协作探索各种方法并在国家边界工作。该项目建立了一个网络，以帮助在该领域工作的科学家共享他们的数据并进行协作。该项目的目的是通过建立Griso（Greenland Ice Speech Ocean）科学网络（一个国际，多学科的开放，开放的科学家和Cyber​​infrastructure Experts），从而实质上增强了多学科活动和协作。参与者对促进与格陵兰冰盖变化有关的问题及其对区域和全球气候的影响的集体理解具有共同的兴趣。 GRISO RCN活动将汇集到格陵兰岛冰/海洋/气氛/气候数据的各个方面的科学家，并为生产性协作互动提供框架。具体目标包括两个研讨会和一系列综合工作。此外，利用现有基础架构的虚拟数据门户将使跨学科数据提交和数据可用性变得更加容易，并促进统一和适当的数据管理实践。 RCN建立在前Griso US Clivar工作组发起的活动的基础上，并明确解决了2013年举行的国际研讨会报告中确定的优先事项。
