The US National Science Foundation has decided to fund the Incorporated Research Institutions for Seismology (IRIS) for the 3-year development of a Greenland Ice Sheet Monitoring Network (GLISN).
The map shows the location of existing real-time broadband seismic stations (red)
joining GLISN with open data sharing and sites (green) where equipment, telemetry,
and infrastructure is being installed and upgraded in concert with GLISN partners.
To monitor glacial earthquakes and other seismic phenomena in the cryosphere in pursuit of an improved understanding of ice sheet dynamics, new broadband seismic stations (green circles in the map) with real-time telemetry will be installed on Greenland's perimeter and ice sheet. In addition, data will be contributed to GLISN from existing broad band seismic stations (red circles) in the Arctic in and around Greenland. NORSAR will provide data to GLISN from its stations in Spitsbergen and on the island of Jan Mayen. Altogether eight countries - Denmark, Canada, Germany, Italy, Japan, Norway, Switzerland and USA - cooperate in this endeavour. All data from GLISN will be freely and openly available to anyone in real-time and without restrictions. An announcement by IRIS on this new project can be found here.
NORSAR is enthusiastic about the opportunity to participate in this timely undertaking. The project has a potential for greatly advancing our understanding of seismic sources associated with movement and deformation of the Greenland ice sheet and of seismicity in adjacent areas of the Arctic. It will strengthen international cooperation in seismology, and we also see this project as an important contribution from seismology to research associated with global change.
