Albuquerque Seismological Laboratory
Sandia Park, New Mexico
Supporting Stations: Palmer Station, South Pole Station
Research Locations: Terra Lab / Seismic Vault, Quiet Sector
The Incorporated Research Institutions for Seismology (IRIS) is a university consortium sponsored by the NSF and dedicated to the operation of scientific facilities for the acquisition, management, and distribution of freely available seismic data. This project is a long-term study of seismicity and is part of IRIS’s 120-plus station Global Seismographic Network (GSN). Seismic stations at Palmer Station and at the Amundsen-Scott South Pole Station are named PMSA and QSPA, respectively. Recently, the South Pole seismic station was moved from the V1 vault (near the old dome site) to SPRESSO to reduce station-related "cultural" noise. The move has made QSPA the quietest seismic station in the entire GSN. Lower background noise levels will allow researchers to see smaller events from farther away and help identify and characterize Antarctic seismicity.
Field Season Overview:
Only routine maintenance will be performed this season. Research assistant training will be accomplished as required.
