Description :
Two 30-m deep permafrost temperature-monitoring boreholes were installed in bedrock, one at Marble Point and one in the Wright Valley, in the Ross Sea region of Antarctica. A soil climate-monitoring station in till is located near each borehole. The main aims of this paper are: (1) to describe the permafrost temperatures and active-layer thermal regime at these two sites in southern Victoria Land; and (2) to derive a climate change record over the last 10 years from the permafrost borehole temperature data and to compare this to measured ground temperatures.
