Permafrost ground temperature monitoring
Detailed Description
A scientist is holding the cable top at a recently relocated site for permafrost ground temperature monitoring in Utqiagvik, Alaska (part of USGS research at the Naval Arctic Research Laboratory from the 1950s to 1970s). The rest of the cable extends into the soil and contains thermistors that used resistivity to measure ground temperature at increments down to 100 ft depth. The USGS is currently digitizing these data and is restarting monitoring of some of the sites.
