| Description |
EarthScope, with funding from the National Science Foundation, provides overall guidance and oversight for the GSN as well as operations of the network code II stations. Additional stations under network codes IU, CU, and IC are operated by the USGS Albuquerque Seismological Laboratory (ASL), who also uses the guidance of the EarthScope GSN Advisory Committee (GSNAC). The remaining stations are designated affiliated stations, meeting the design goals of the GSN but operated outside the funding of NSF and USGS. Operations of the NSF-funded portion of the GSN transitioned from the University of California, San Diego/Project IDA to the EarthScope Consortium in September 2024. |
