Questions addressing Arctic change span earthquakes, meteorology, climate, sea ice, glaciers, permafrost, and wildfire. Many change-based research questions require consistent and continuous long-term data. By co-locating a wide variety of geophysical instruments, the Alaska Geophysics Network lends itself to enhancing cross-disciplinary research. Our stations co-locate: a 3-component broadband seismometer (Nanometrics T120PH or Kinemetrics STS-4B/5A); a Vaisala WXT weather station; a MEMS state-of-health barometer; a NCPA infrasound sensor; a SETRA microbarograph; and an Onset HOBO soil temperature profile. The stations were originally part of 192 multi-sensor platforms installed across Alaska between 2014 and 2017 by the USArray seismic project, managed by the Incorporated Research Institutions for Seismology (IRIS) as part of the NSF EarthScope program. These stations vastly expanded the amount of data available in Alaska and marked the first time seismic instruments were installed in some remote locations. Following the commencement of the USArray project, the Alaska Earthquake Center adopted the best-performing stations to become part of our permanent monitoring network. Data collected by the Alaska Geophysics Network can help explore questions related to climate, earthquakes, landslides, glaciers, sea ice, weather, wildfire, and more. All data is available for public use. In this presentation, we show the extent of the network and data and examples of cross-disciplinary cryoseismology findings from the Alaska Earthquake Center using this data.
