NOAA Thermal Springs and Geothermal Gradient Data

Geothermal resource data includes a list of 1,700 thermal springs in 23 U.S. states and a map of 1,700 wells with heat flow measurements. The data was compiled by NOAA National Centers for Environmental Information and various researchers, with primary publications dated 1981 and 1982.

Use Cases

• Map thermal spring locations using state, latitude, and longitude fields.
• Analyze geothermal potential using maximum surface temperature in degrees Celsius and Fahrenheit.
• Correlate heat flow data with conductivity measurements from the geothermal gradient map.
• Identify natural hydrothermal features such as springs, pools, mud pots, and geysers from the thermal springs list.
• Cross-reference site data with USGS topographic map coverage information.

Strengths

• Contains 1,700 thermal spring locations.
• Includes 1,700 wells with heat flow data.
• Provides temperature data in both Fahrenheit and Celsius.

Limitations

• Data is from primary publications dated 1981 and 1982, with last update noted as 1985.
• Limited to 23 U.S. states, lacking global coverage.
• Does not include wells or mines except in specific supplemental cases.
