Ground temperature profiles from DVDP borehole 11 at Explorers Cove, McMurdo Dry Valleys, Antarctica (2020-2025, ongoing)

The Dry Valley Drilling Project (DVDP) drilled multiple boreholes throughout Antarctica’s McMurdo Dry Valleys in the early 1970s, several of which remain open and accessible. DVDP borehole 11, with a total depth of 327.86 m, is located adjacent to the Explorers Cove Meteorological Station (EXEM), operated by the McMurdo Dry Valleys Long Term Ecological Research program (MCM LTER). In January 2020, the MCM LTER instrumented this borehole with a string of thermistors to monitor ground temperatures through the permafrost. Sensors were installed at depths of 1, 2, 3, 4, 5, 10, 20, and 30 m, providing ongoing measurements of subsurface thermal conditions at Explorers Cove.
