Geodetic Facility for the Advancement of EarthScope The Geodetic Facility for the Advancement of EarthScope (GAGE) was a United States national facility that supported geodetic investigations across North America and provided instrumentation, data, and expertise for plate boundary, seismic, volcanic, and crustal deformation studies. GAGE served researchers by operating and maintaining geodetic networks, coordinating with observatories, and enabling projects that involved space geodesy, seismology, and geodynamics.
GAGE acted as a service and operations center serving programs such as EarthScope, Plate Boundary Observatory, UNAVCO, University of Nevada, Reno, and the National Science Foundation, while interfacing with institutions including Scripps Institution of Oceanography, Massachusetts Institute of Technology, California Institute of Technology, Lamont–Doherty Earth Observatory, and Jet Propulsion Laboratory. The facility provided access to instruments like Global Positioning System, Very Long Baseline Interferometry, Satellite Laser Ranging, and Interferometric Synthetic Aperture Radar through partnerships with agencies such as NASA, United States Geological Survey, NOAA, European Space Agency, and Canadian Space Agency. GAGE supported campaigns and long‑term monitoring that linked field observatories such as Yellowstone National Park, San Andreas Fault, Cascadia Subduction Zone, Long Valley Caldera, and Wasatch Fault Zone with modeling centers including Scripps Institution of Oceanography and Stanford University.
GAGE evolved from initiatives funded by the National Science Foundation and coordinated with the EarthScope program, beginning in the early 2000s with contributions from facilities like the Plate Boundary Observatory and projects at University of Colorado Boulder, University of California, Berkeley, University of Washington, and Pennsylvania State University. Early implementation drew on expertise from legacy projects such as the Global Geodetic Observing System and collaborations with International GNSS Service, Fédération Internationale de Géomètres, and observatories at Harvard University, Princeton University, Brown University, and Columbia University. Key milestones included deployment of continuous GPS stations tied to networks operated by IRIS (Incorporated Research Institutions for Seismology), upgrades coordinated with NASA Jet Propulsion Laboratory, and data stewardship practices influenced by Data Conservancy models and policies from Office of Science and Technology Policy.
GAGE managed a range of geodetic instrumentation: continuous GPS receivers, dual‑frequency antennas, geodetic monuments, borehole strainmeters, tiltmeters, and meteorological sensors, integrating measurements from VLBI sites, SLR arrays, and InSAR processing centers. Equipment acquisitions involved suppliers and laboratories such as Trimble, Topcon Positioning Systems, Leica Geosystems, JPL, and university labs at Massachusetts Institute of Technology and University of Texas at Austin. Field facilities included instrument pools, calibration labs, and mobile units deployed for rapid response to events like earthquakes recorded by Southern California Seismic Network, Alaska Earthquake Center, Pacific Northwest Seismograph Network, California Integrated Seismic Network, and volcanic unrest at sites monitored by the United States Geological Survey Volcano Hazards Program.
GAGE enabled research on tectonics, seismic cycle processes, magmatism, post‑glacial rebound, and anthropogenic deformation by supporting projects at Stanford University, University of California, Santa Cruz, Cornell University, University of Oregon, University of Alaska Fairbanks, University of California, Los Angeles, and international groups at University of Tokyo, ETH Zurich, Imperial College London, University of Cambridge, and University of Oslo. Studies used GAGE data to investigate the San Andreas Fault system, Cascadia Subduction Zone megathrust, Yellowstone caldera, Alaska subduction zone, Denali Fault, Wasatch Fault, Rio Grande Rift, and post‑seismic deformation following events such as the 2011 Tōhoku earthquake and tsunami and the 1994 Northridge earthquake. Modeling and assimilation work linked to centers like NASA Goddard Space Flight Center, National Center for Atmospheric Research, Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and Sandia National Laboratories advanced hazard assessment and geodynamic interpretation.
GAGE operated data systems that archived and distributed continuous geodetic time series, metadata, and campaign results through repositories and protocols used by IRIS, UNAVCO, International GNSS Service, DataCite, ORCID, and node services at DataONE and EarthCube. Data formats and standards aligned with initiatives from Open Geospatial Consortium, International Association of Geodesy, Committee on Earth Observation Satellites, and policies from the National Science Foundation and NASA. The facility supported tools for data discovery, visualization, and processing developed in collaboration with software projects at University of California, San Diego, Carnegie Mellon University, University of Michigan, and Princeton University.
GAGE partnered with federal agencies and research institutions including National Science Foundation, NASA, United States Geological Survey, NOAA, Natural Resources Canada, and international partners at European Space Agency, Geoscience Australia, and Japan Aerospace Exploration Agency. Academic collaborations included University of Nevada, Reno, Scripps Institution of Oceanography, Lamont–Doherty Earth Observatory, Stanford University, University of Colorado Boulder, University of Washington, and consortia such as IRIS and UNAVCO. Cooperative projects linked to programs like EarthScope, GEONetCast, Global Geodetic Observing System, and regional networks such as Pacific Northwest Seismic Network and Southern California Seismic Network.
GAGE engaged in outreach through training workshops, short courses, community meetings, and educational modules for students and professionals in partnership with UNAVCO, IRIS, American Geophysical Union, Seismological Society of America, Society of Exploration Geophysicists, and university extension programs at University of Nevada, Reno, University of Colorado Boulder, and California Institute of Technology. Public‑facing activities included presentations at conferences hosted by AGU Fall Meeting, EGU General Assembly, Seismological Society of America Annual Meeting, and contributions to resources used by teachers and students in association with Smithsonian Institution programs and national parks such as Yellowstone National Park and Yosemite National Park.
