Permafrost extends to specific depths in the Antarctic.
Multiple studies demonstrate that permafrost in Antarctica extends to measurable depths, such as tens of meters in the Dry Valleys and maritime Antarctic regions.
The retrieved papers include direct empirical measurements of permafrost depth and thermal properties at specific locations in Antarctica (such as Livingston Island and the McMurdo Dry Valleys), directly supporting the claim that permafrost extends to specific depths on the continent.

This study measures permafrost depth via boreholes on Livingston Island, showing it extends to several decametres in the maritime Antarctic.
