Welcome to the Alaska Division of Geological & Geophysical Surveys

Our mission: Determine the potential of Alaskan land for production of metals, minerals, fuels, and geothermal resources, the locations and supplies of groundwater and construction material, and the potential geologic hazards to buildings, roads, bridges, and other installations and structures (AS 41.08.020).


  • New seismic and well data available: Harrison Bay 3D (MLUP/NS 03-004-03), Nanuq South 3D (MLUP/NS 03-004-02), and Storms 3D (MLUP/NS 04-006). See our data request form for more info.
  • Fees for services at the GMC are now effective as of November 9, 2017. Set by Director's Order, the fees will help offset operational costs at the Geologic Materials Center and solidify the facility's long-term viability.
