Name: Changes in Permafrost Temperatures in Alaska, 1978–2020

Display Field: Site_Name

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This map shows the change in permafrost temperature per decade for long-term borehole sites in Alaska. As the circles get larger, the rate of warming per decade increases. The blue circle represents a cooling trend. Borehole measurement depths range from 49 to 85 feet.
