Borehole thermometry data from Rutford Ice Stream, West Antarctica, 2007
Borehole temperature measurements from the upper 300 m of Rutford Ice Stream. A string of thermistors was installed into a hot-water drilled hole in February 2005. The string comprised 10 calibrated thermistors at approximately 30 m spacing. The temperature measurements provided were taken in Februa...

Borehole temperature measurements from the upper 300 m of Rutford Ice Stream. A string of thermistors was installed into a hot-water drilled hole in February 2005.

Prior to deployment each thermistor had been calibrated. Wires to each thermistor extended down from the surface.
