Alaska Geothermal Database

The Alaska Division of Geological & Geophysical Surveys (DGGS) completed a cooperative project with the National Geothermal Data System on thermal springs and related geothermal data of Alaska. The Alaska geothermal database modules include comprehensive information on thermal springs, including temperature and flow rates, direct use, aqueous spring chemistry, physical samples, volcanic vents, geothermal wells, borehole temperature data and geothermal references.
