The Greenland Ice Sheet Monitoring Network (GLISN) is a broadband, multi-use seismological network, enhanced by selected geodetic observations, designed with the capability to allow researchers to understand the changes currently occurring in the Arctic, and with the operational characteristics necessary to enable response to those changes as understanding improves. GLISN was established through an international collaboration, with 10 nations coordinating their efforts to develop the current 32-station observing network during the last four years. This project will continue operations of six key stations of the network, as well as data quality control and data-management for the network. It will also improve the telemetry capability at remote stations to maximize the scientific utility of the data, reduce data latency, and reduce logistics costs. Continued leadership by IRIS in the management and coordination of the International GLISN effort will ensure continued return of high-quality data from the full 32-station network. Observations from the GLISN network will allow improved estimation of the Earth structure under Greenland, critical for reliable estimation, interpretation, and prediction of changes in ice mass, sea level, and the crustal stress state. These observations will also allow greatly improved analysis of deformation within the ice sheet and at its calving margins due to processes including discrete ice-loss events, melt-water drainage, crevassing, and basal sliding. Seismic analysis provides unique information about glacier dynamics and sub-glacial geology, complementing other remote-sensing and in-situ observations. GLISN science and outreach will leverage and enhance outreach and education programs undertaken by the IRIS Consortium and its community.

格陵兰冰盖监测网络（GLISN）是一个宽带，多用途的地震学网络，通过选定的测量观测来增强，其设计具有使研究人员能够理解北极中当前发生的变化，并且具有对这些变化的响应所必需的操作特征，以提高理解。 Glisn是通过国际合作建立的，在过去四年中，有10个国家协调他们为开发当前32座观察网络的努力。 该项目将继续对网络的六个关键站进行操作，以及网络的数据质量控制和数据管理。它还将提高远程站点的遥测能力，以最大程度地提高数据的科学效用，减少数据延迟并降低物流成本。艾里斯（Iris）在国际GLISN努力的管理和协调方面的持续领导将确保从完整的32个站网络中继续返回高质量数据。 GLISN网络的观察结果将允许对格陵兰岛下的地球结构进行改进，这对于可靠的估计，解释和预测冰块，海平面和地壳应激状态的变化至关重要。 这些观察结果还将大大改善冰盖内部变形的分析以及由于包括离散的冰损伤事件，融化水排水，裂缝和基础滑动的过程，其产犊缘。地震分析提供了有关冰川动力学和亚冰川地质学的独特信息，并补充了其他遥感和原位观察。 Glisn Science and Otercre将利用和增强Iris财团及其社区进行的外展和教育计划。
