Welcome to GRISO
The Greenland Ice Sheet has lost over 5000 Gt of ice over the last four decades causing global sea level to rise by more than 14 mm. A significant fraction of this ice loss is due increased ice discharge from marine terminating glaciers likely driven by changes in melting at the ice/ocean interface. In parallel, the anomalous discharge of freshwater and sediments from the Greenland Ice Sheet is impacting the regional climate, including its ecosystems, with potentially far-reaching global consequences. These changes have generated increased interest in the interactions of the ocean and its marine ecosystems, the glaciers, and the atmosphere at Greenland’s. The complexity of the processes involved, the inherently multidisciplinary nature of the problem and the challenges of obtaining measurements from this region, make Greenland ice sheet/ocean interactions a new research frontier that requires collaboration across disciplines and national boundaries, a suite of diverse approaches and the development of novel technologies
The GRISO Science Network is an international, multidisciplinary group of scientists interested in advancing collective understanding of problems related to Greenland ice sheet change, and its interaction with the ocean, the atmosphere and the marine ecosystems. It builds on activities initially led by the U.S. CLIVAR Working Group on Ice Sheet Ocean Interactions, and continued through a series of activities primarily funded by the National Science Foundation. Specific objectives of this group are:
- to facilitate the interaction of groups and disciplines working on different aspects of this problem
- to lead to sharing of, and easy access to resources, including data, infrastructure and personnel
- to lead efforts to inform scientists, policymakers and the public on the problem,
- to work towards implementing the recommendations identified in a number of community workshops and described in the reports.
