The U.S. National Science Foundation's Seismological Facility for the Advancement of Geoscience (NSF SAGE) is a distributed, multi-user national facility that provides support for state of-the-art seismic research. It is operated by EarthScope Consortium. Its previous operator was the Incorporated Research Institutions for Seismology (IRIS), until its merger with UNAVCO to become EarthScope Consortium.[1][2] NSF SAGE is one of the two premier geophysical facilities in support of geoscience and geoscience education of the National Science Foundation (NSF).[3] The other premiere geophysical facility is NSF GAGE, the Geodetic Facility for the Advancement of Geoscience.
The services of the facility include support for the Global Seismographic Network (GSN), Data Services, and instrument support via the EarthScope Primary Instrument Center (EPIC), including magnetotelluric (MT) geophysical research.
