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.

格陵兰岛的冰损失在过去二十年里翻了两番，目前占全球海平面上升的四分之一。冰损失是由于与空气和海洋温度上升相关的表面质量平衡和冰盖动力学的变化造成的。与之相关的淡水排放量的增加正在影响区域海洋，包括其生态系统，并有可能影响大规模的北大西洋环流。因此，格陵兰岛的变化正在对全球社会产生深远的影响，但造成这些变化的机制尚不清楚。特别是动态冰损失，很可能是由海洋终止冰川边缘的变化引发的，通过气候、冰盖和海洋模型中不存在或很少体现的冰/海洋/大气过程。格陵兰岛边缘海洋、冰川和大气的相互作用是一个新的研究前沿。所涉及的复杂过程包括地球系统多个组成部分的耦合、获取和集成来自该地区的不同数据以及对这样一个复杂系统进行建模的挑战。这些挑战使得这个问题只能通过将包括数据管理在内的多个学科结合在一起、协作探索不同的方法以及跨国界工作来解决。该项目建立一个网络，帮助在该领域工作的科学家共享数据并协作工作。该项目的目标是通过建立 GRISO（格陵兰冰盖海洋）科学网络，大幅加强多学科活动和协作 -一个由科学家和网络基础设施专家组成的国际、多学科、开放的网络。与会者对增进对格陵兰冰盖变化相关问题及其对区域和全球气候影响的集体理解有着共同的兴趣。 GRISO RCN 活动将汇集专注于格陵兰岛冰/海洋/大气/气候数据各个方面的科学家，并为富有成效的协作互动提供一个框架。具体目标包括两次研讨会和一系列综合工作。此外，利用现有基础设施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 以前 GRISO US CLIVAR 工作组发起的活动为基础，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。
